Thermoplastic elastomers ( TEP) or thermoplastic elastomers (TPE, TPE, thermoplastic elastomer)- these are synthetic polymers, which at ordinary temperatures have the properties of rubber, and at elevated (120-200 ° C) - soften, like thermoplastics. Unlike rubbers, TPEs are processed into rubber products, bypassing the vulcanization stage.

The combination of these properties is due to the fact that TEP is a block copolymer, in the macromolecules of which elastic blocks (for example, polybutadiene) alternate in a certain sequence with thermoplastic ones (for example, polystyrene). The fields of application of thermoplastic elastomers are diverse.

It is a material that combines the properties of vulcanized rubbers at normal and low temperatures with the properties of thermoplastics at 120 ° C-200 ° C. TPE can be processed like plastics on standard equipment by means of molding, extrusion, injection molding with low process losses. At the same time, due to the absence of the need for vulcanization, it creates the possibility of multiple re-processing of waste in the manufacture of products.

The fields of application of thermoplastic elastomers are diverse. This is the automotive, cable industry, electrical, rubber, polymer industry, consumer goods and more.

Building materials (seals, including for windows, flexible roofs, asphalt), car parts (window seals, bumpers, interior parts), medical materials (storage and blood transfusion systems), tools (elastic pens, shockproof elements), shoes(sole), hygiene items (toothbrushes, shaving sets), household appliances (camcorders, cameras) and children's attributes (nipples and toys) - all these necessary goods are now made of TPE material, which confirms its safety and durability.

Shoes with a TEP sole has a number of indisputable advantages, such as durability, lightness, flexibility and ease of use. Inexpensive material is indispensable for both children's and adult shoes. It shows its best qualities both in winter and in summer, it allows you to feel comfortable on any irregularities in the road.

Advantages T ermoelastoplasts :
1. Excellent ozone and UV resistance;
2. High elasticity even at 60 ° С frost;
3. High strength and tensile strength;
4. High durability, over 30 years;
5. The color of the sealant is determined by the dyes. The intrinsic light color of thermoplastic elastomer allows the production of seals in different shades of color by adding colorants;
6. Chemically resistant to most chemicals;
7. Does not require special care and replacement;
8. The problem of blowing in the corners is reduced to zero, because when welding the frame, the seal is also welded.

By changing the formulations of thermoplastic elastomers, it is possible to regulate their basic physical and mechanical and consumer properties: hardness, elasticity, oil and petrol resistance, frost resistance, fire resistance, color. Products made of thermoplastic elastomers have a homogeneous structure.

But the most important thing is that it is the properties TEP guarantee the functioning of products without loss of operational properties for many years under the influence of constantly changing atmospheric factors (frost and heat, high and low humidity, etc.).

Thermoplastic elastomers are obtained by the methods used for the synthesis of polymers: polymerization (radical, cationic, anionic), polycondensation, mechanochemistry. processing of mixtures of polymers or a combination of different methods.

The greens love TPE because it is 100% recyclable, chlorine and sulfur free. New thermoplastic elastomers do not contain lead stabilizers and other heavy metals. Another positive property of the new thermoplastic elastomers, from the point of view of ecology, is the reduced migration of the plasticizer.

TEP-good dielectric, electrical cables, cords and other insulators are made from bliss.

It is also worth noting that thermoplastic elastomers are subdivided into several types, depending on which component is the basis of the thermoplastic elastomer. So, they are divided into:

The main components determine the characteristics of thermoplastic elastomers, as well as their area of ​​application. In this case, the main standardizing indicator of the TPE brand can be called hardness - usually it ranges from 25 Shore A to 60 Shore D. However, regardless of the type of thermoplastic elastomers, they are all stable in a wide temperature range, while In some cases, they are even superior in these characteristics to synthetic and natural rubbers.

Just like rubbers, thermoplastic elastomers allow you to add various mineral fillers or stabilizers with plasticizers to their composition. This allows you to control the properties of thermoplastic elastomers. So, they can possess:

• Good mechanical strength;
• High ability to resist UV radiation, ozone or moisture;
• High weather resistance;
• Good resistance to chemical attack, as well as high petrol and oil resistance;
• Excellent flexibility as well as toughness at high and low temperatures;
• High wear resistance;
• Improved properties at low temperatures;
• Durability;
• Impact resistance;
• Elasticity;
• High resistance to fatigue, etc.

In addition, thermoplastic elastomers have the ability to improve their strength characteristics over time, in contrast to rubbers, which lose elasticity, become brittle and brittle.

TPE retain elastomeric properties at temperatures from -65 ° C to + 150 ° C.

Thermoplastic elastomers are used in the following types of products:

Transition sleeves - transition sleeves are used to connect the drain to the sewer pipe.

Modern manufacturers regularly update the range of materials used to make shoe soles. One of the most recent solutions - thermoplastic elastomer, or TEP .

Shoe sole made of thermoplastic rubber; fundamentally new material for shoe soles:

So, TEP sole - what is it? This material is created on the basis of thermoplastic rubber, which combines the best properties of thermoplastics and elastic rubber. Plastic and wear resistant thermoplastic elastomer Is the best solution for making soles for both winter and summer footwear. It copes well with high loads, allowing the boots to last for more than one year, tolerates high and low temperatures well, and is resistant to chemicals.

Winter summer

The thermoplastic elastomer is easy to correct. The addition of polymers to the formula of the material in certain proportions makes it possible to create a TEP sole with varying degrees of elasticity for any season or load. Thus, technologists practically reach perfection - the most frost-resistant shoes for severe frosts or wear-resistant summer models that do not hinder movement and are practically weightless. Sole TEP, reviews of which are overwhelmingly positive, is an undoubted advantage of shoes.

Combined outsole

On the basis of thermoplastic elastomer and polyurethane, shoe soles are made with marking TPU... The combination of durable and frost-resistant TPE and light and soft PU makes the material especially valuable. The TPE / PU outsole combines all the advantages of both materials, in addition, it is available in any color: from standard black to hot pink, blue and light green colors. This is especially important in the production of bright and beautiful children's shoes. Saturated colors do not fade in the sun, do not fade and last for many years.

The main advantages of polymer soles

The class of soles, which include certain polymers, has a number of indisputable advantages. It:

Main advantages

TEP sole - what is it? Surely this question was asked by every buyer of footwear created using a material that combines the most modern technologies and the ideas of each of us about comfortable, comfortable and durable footwear. Thermoplastic elastomer has a number of characteristics that speak in favor of the choice boot, moccasins or boots made of such material. Sole TEP, reviews of which are mostly positive, pleases almost everyone. Buyers note:

Winter shoes with TPE-sole

When choosing winter shoes, safety becomes one of the most important conditions. You need to feel confident even in the most unfavorable weather conditions. That is why it is important to know whether the TPE sole is slipping or not. Does not slip! Equipped with a raised protector, it avoids injury even in ice.

Another plus that speaks in favor of choosing winter shoes with a TEP-sole is frost resistance. The elastic material feels great in the most severe frosts, without cracking even at a temperature of -45 degrees. The TEP sole helps to keep the feet warm and dry in winter. You will be as comfortable as possible even when walking for hours in the snow or going to work on the autumn slushy streets. Shoes with TPE sole - a guarantee of your safety and confidence in any weather.

Summer and demi-season models

Choosing winter shoes, buyers ask: "Does the TEP sole slip or not?" But when choosing models for other seasons, the first place comes to the question of the wear resistance of shoes or boots in conditions of constant contact with the asphalt surface. TEP sole - what is it and how does it behave in summer? It is very flexible, so it absolutely does not hinder the movements of the foot. Light and beautiful shoes will last for more than one season, without losing its original attractiveness, brightness and other properties.

The lightness of shoes with TPE soles is due to the fact that only the outer layers of the material are monolithic. The inner layers are porous, which means they are practically weightless. TPE (thermoplastic elastomer-sole) absorbs well when walking, allowing you to feel comfortable even with intense loads or uneven surfaces.

Children shoes

Most often in children boot or shoe sole - rubber or TEP... By opting for the latter option, you choose lightness, flexibility, frost resistance and durability. A small child is able to run a lot of kilometers in a day, which means that his legs should not get tired or sweat under any load. The most active baby will feel comfortable and cozy in high-quality shoes with thermoplastic elastomer soles, of course, provided that the size and top of the boots are properly selected or boot... Bright models will appeal to any fashionista or fashionista.

TEP sole material - what is it? How safe is it for a child of a given age? Does it cause allergic reactions? Such questions are asked by young mothers in many forums. Indeed, on how comfortable the child will be, it directly depends on how correctly the foot will be formed in the future. Reading reviews about children's shoes from TEP, one can come to the conclusion that it is absolutely safe and comfortable for any age, does not hinder movement, does not deform and does not cause any inconvenience during operation. Kids feel great in shoes with TEP-soles and on a walk in the winter park, and when playing on the children's summer playground. Legs don't slip shoes does not hinder movement, does not weigh down the leg.

TEP sole is an affordable solution!

Thermoplastic elastomer is inexpensive, so it is available for the budget of any family shoes, in which there is a TEP sole. The price of cozy and warm felt boots for a child, for example, is about 1000 rubles. The advantage of such shoes is not only in savings when buying, but also in the possibility of long-term use, as they are worn felt boots really long without deformation at low temperatures and constant loads. Moreover, the quality of the material is much higher than its cost. Today, many global footwear manufacturers opt for thermoplastic elastomers. This allows you to significantly reduce the cost of products, and therefore attract new grateful buyers. This is especially true for children's shoes, which have to be bought more often than adults, and the price really matters.

Other types of sole materials

Among the most popular materials used for the production of soles of children's and adult shoes today are the following: rubber, leather, rubber, polyvinyl chloride. Each has a number of advantages and disadvantages. For example, a leather sole allows the foot to breathe, but it does not boast of wear-resistant properties. Besides leather- quite an expensive option, often used for luxury footwear. For everyday socks usually use shoes with a more practical sole, which is no less beautiful and safe.

Used in the manufacture of soles and natural wood or plywood. Such material is as environmentally friendly as possible. However, it wears out rather quickly, is easily exposed to moisture and chemicals.

Rubber is a cheap material, but rather capricious, reacting negatively to the effects of low and high temperatures. Moreover, such shoes slips heavily, which is unacceptable in our harsh winter and traditionally slippery roads.

Another thing is the material of the TPE sole. What is it? This is a combination of all the qualities necessary for durable and comfortable footwear. Comfortable, lightweight and high-quality sole will make any model truly beloved and regularly worn.

Environmental friendliness

Above, we talked about what characteristics the TEP sole has. What it is? These are quality, lightness, durability, etc. However, the advantages do not end there. Today, when every schoolchild is aware of environmental problems, concern for nature comes first. Thermoplastic elastomer is one of the few modern materials that can be recycled, which means it does not pollute the environment. This property of the material will surely attract the attention of everyone who cares about the health of their own and future generations. By choosing shoes with TPE outsole, you choose high quality and environmental friendliness at the most affordable price.

Disadvantages of TPE-soles

Despite the many indisputable advantages, there are also some disadvantages. This is the inability of the material to withstand temperatures above +50 and below -45 degrees. Of course, in the face of everyday socks such characteristics are not very important. Agree, the weather rarely surprises with such phenomenal temperatures. However, for example, for an employee of the metallurgical industry who visits hot workshops every day, such a sole will not work.

Considering that extreme temperatures are rare, this disadvantage can be considered insignificant and does not play a big role in the choice. Shoes with a thermoplastic elastomer sole - this is an excellent option for everyone who wants to purchase a high quality product at an affordable price!

Different groups of TPEs are formed on the basis of the chemical difference of the constituent polymers. Several groups are based on a polymer consisting of macromolecules that combine rigid and elastic blocks. These are block copolymers, including thermoplastic styrene elastomers (SBS), thermoplastic urethanes ( TPU), copolyesters COPE), copolyamides (COPA).
Other groups are compounds of rigid and elastic polymers that are compatible enough to provide bonding. They include thermoplastic compounds of polyolefin elastomers (TPO) and polypropylene with polyvinyl chloride / butadiene-nitrile rubber compounds (PVC / BNK). Another group unites separate rigid and elastic polymers that have entered into chemical reactions to enhance mechanical properties, especially at the cross-linking sites of the elastomer phase. TPEs with a crosslinked elastomer phase are thermoplastic vulcanizates (TPVs) and generally have the mechanical properties of the thermoplastic rubber class. The sharp quantitative growth of products in these areas continues, especially for thermoplastic vulcanizates (TPV).

Thermoplastic elastomers: latest developments

Materials (edit)
New developments are being implemented in many types of TPEs. Below is a summary of each technology. The list is categorized by TPE types.

Thermoplastic Styrene Elastomers (SBS)
SBS falls into two general categories: saturated and unsaturated polymers. Unsaturated SBS, including styrene-butadiene block copolymers and styrene-isoprene-styrene block copolymers, are materials with a low melting point, they are more susceptible to thermal degradation, have low chemical resistance, and are more economical. Saturated SBS, mainly styrene-ethylene-butylene-styrene block copolymers, have a high melting point, high resistance to thermal degradation, and increased chemical resistance. Recent developments in SBS include very soft formulations with gel properties and low Shore A 5-10 hardness. Also recently introduced classes of SBS with optical transparency. SBSs have been developed to react as TPVs to give them higher shape memory and sealing characteristics, increased chemical resistance and higher temperature of use.

Polymer mixtures TEP
The most common polymer mixtures of TPEs are thermoplastic polyolefin elastomers (TPO), which are a mixture of a ternary copolymer of ethylene, propylene and diene with polypropylene. They have been used commercially for several years, but they continue to develop actively due to their cost effectiveness. Thanks to the development of reactor olefins, which increase efficiency and, apparently, economy, new TPO developments are being introduced. Organometallic catalytic polymerization of olefins led to the development of polymer molecules with desired properties. Some of them are more similar to block copolymers, due to the control of the copolymerization of ethylene and propylene with other diene olefins. The development of new olefinic polymers, including elastic polyolefin elastomers (POEs) and semi-rigid polyolefin plastomers (EPPs), has opened up a range of new tailored products, especially TPO products.

Thermoplastic vulcanizates (TPV)
The developments in the field of TPV continue to actively develop, therefore, the growth rates of TPV are leading among all types of TPE. TPV's largest development is based on blends of ethylene-propylene-diene-polypropylene terpolymer (DPE / PP).
The latest advances in crosslinking chemistry have been leveraged to provide improved TPR properties. The DPE / PP grades in multicomponent molding are usually associated only with olefins. This barrier has been overcome by the development of grades that bind perfectly to polyamides, especially nylon 6, and grades that bind to acrylonitrile butadiene styrene copolymers (ABS copolymer), polyester and other technical thermoplastics. Figure 1 shows a photograph of the effective application of the DPE / PP TPV technology in the manufacture of pens stapler. Recently, the range of the most flexible materials DPE / PP TPV has expanded to 25 Shore A.

Rice. 1. Soft pens staplers made of thermoplastic vulcanizate.

For cheaper applications with less stringent technical requirements, TPV (r-TPV) based on recycled materials have been introduced, where the rubber phase is cross-linked recycled rubber. In the rubber phase, as a rule, natural or styrene-butadiene rubber is used, therefore the upper limit temperature for the use of the material coincides with the limit temperatures of natural and styrene-butadiene rubber. Several new types of TPR have also recently been introduced, including TPR with a silicone rubber phase. It is called thermoplastic silicone vulcanizate (TPSiB). This soft, velvety material can be used at a constant temperature of 140-150 ° C.
Although TPR materials with higher water resistance have already been introduced, such as nitrile rubber (NBR), combined with NBR / PP TPV with the nitrile rubber phase in PP, their use was limited to a maximum temperature of 150 ° C or a practical limit of 125 ° C. New TPVs with high water resistance and an increased temperature limit of 177 ° C are introduced with an acrylate rubber (AEM) phase and a technical thermoplastic phase. They are designated as AEM TPV.

Thermoplastic polyurethanes ( TPU )
Block copolymers TPU are the very first TPE products to be used commercially. New developments continue to be introduced. Latest commercial developments TPU have increased heat resistance. New classes with increased softness up to 20 Shore A.

Copolyester TPR (COPE)
Copolyesters COPE remain an important technical grade of TPE, which is also gaining more and more commercial development. New COPE classes are being introduced to meet specific technical requirements. It is important to note that in recent years, classes with increased elasticity and resistance to fatigue during deformations have been introduced.

Properties
TPEs have the same basic properties as thermoset rubbers (natural rubber, neoprene rubber, DPE rubber, etc.). TPE and thermoset rubbers are classified according to their ability to withstand temperatures and resist hydrocarbon fluids (oils, slurries, fuels, etc.) These properties are generally presented in the diagram, where the ranges of properties of TPE or rubber are indicated. These new developments of TPEs are presented in Figure 2 by different classes of TPEs, and Figure 3 shows thermoset rubbers.

Rice. 2. Thermal stability of TPE to the action of oils.

Rice. 3. Temperature resistance of thermosetting rubbers to the action of oils.

These classes of TPE are classified by performance characteristics, the most important of which is hardness or elasticity. Hardness is usually indicated by Shore A or Shore D. The approximate commercially available hardness range for different TPEs is shown in Figure 4. The extended hardness range for several grades is highlighted in color.

Rice. 4. Range of hardness for different classes of TPE.

The cost of TPE products depends on several factors, including the economy of plastics processing and the cost of the material. The relative priority of the different classes depending on temperature / oil resistance is shown in Figure 5; the latest TPE classes are highlighted in color.

Rice. 5. Comparison of the dependence of the cost and operational characteristics of the TEP classes.

Application
The performance characteristics of various classes of TPEs allow them to be used commercially in most areas of industry. The latest developments in TPV and TPSiV are highly oil resistant materials that meet the temperature requirements for a wide range of technical applications such as engine hood seals, shrouds and hoses.

Rice. 6. Soft pens made of copolymer of ethylene-propylene-diene and polypropylene (DPE / PP TPV) for kitchen measuring cups and spoons

COPE, with its lower hardness and increased dynamic elasticity, is the preferred material for high elasticity products such as car pads. The softness of the materials DPE / PP TPV determines their use as holders and handles for household items, including tools and utensils. Dishes requires compliance with food contact regulations, therefore, there are special TPVs in commercial use that meet the requirements for household utensils and liners for food containers. Figure 6 shows a set of kitchen household items with colored TPV handles.
The latest polyolefin elastomers POE and POP have opened up new possibilities for use in large-scale applications and as components of TPEs. Some of these will prove useful for automotive interiors and other soft resilient surfaces where a PVC compound will be used.
The new R-TPE formulations are very economical and are tailored for low oil and heat resistance applications: automotive mud flaps, pad fencing, rugs at the entrance and sound-absorbing pads. Due to their cost effectiveness, they replaced plasticized rubber protective coatings.

Recent developments in the field of thermoplastic elastomers ( TEP) have led to a significant improvement and expansion of operational characteristics. The improvements have overcome some of the limitations of using TPE for technical applications with new TPV and TPSiV. Soft materials can be produced from embedded developments of SBS or soft TPV. The surface quality of vehicle interiors and possibly exterior components will be greatly improved by the use of low hardness metallocene olipheins, POE, and semi-rigid POPs. These materials will also prove useful as raw materials for manufacturers developing specialized TPEs for various TPE classes. COPE is soft and resistant to dynamic bending, allowing for the development of automotive pads and related technical devices. Finally, as an alternative to plasticized rubber and thermoplastic rubber, there will be economical, easy-to-manufacture R-TPE based on recycled products.

Thermoplastic rubber, EVA, PVC, thermoplastic elastomer or polyurethane? Shoes with soles from which material to give preference?

Leather

A material used to make shoe soles since time immemorial. Shoes with leather soles look great and breathe perfectly. The leather sole is available in one, two or even three layers. It is most often used in the production of high-quality luxury footwear.

The wear resistance of the leather is rather low, and therefore prophylaxis should be installed on the sole made of such material. It is especially important to have prophylaxis in winter shoes, since without it there will be a leather sole.

Wet leather is prone to deformation, so it is better to refuse to wear shoes with leather soles in rainy weather. The leather sole needs constant care with the use of special impregnations and sprays.

Tunit

This material also has another name - leather fiber, which is a mixture of rubber and leather fibers.

Outwardly, no different from leather, tunite soles surpass them in their performance. They do not get wet and are abrasion resistant. Reliable adhesion to the ground provides them with a relief pattern, which is much easier to perform on tunit than on skin.

Nevertheless, in the cold season, tunite soles do slip, so they are most often used for the production of summer and demi-season shoes.

Thermoplastic elastomer (TPE, TRP)

Thermoplastic elastomer is considered an all-weather material. It combines elasticity and strength. Resistant to wear and tear. TPE outsole features excellent cushioning and high traction.

Features of the manufacturing technology make it possible to make the outer surface of thermoplastic elastomer products monolithic, ensuring their strength, and the inner space - porous, due to which the TPE soles have high thermal insulation properties.

Another important point is that thermoplastic elastomer products do not pollute the environment, since they can be recycled and reused.

Polyurethane (PU, PU)

Due to its porous structure, polyurethane has a relatively low weight, has good shock absorption properties and thermal insulation. Polyurethane soles are flexible and wear resistant at the same time.

Polyurethane also has disadvantages: soles made of this material slide on snow and ice at low temperatures, and in the case of active use of shoes with polyurethane soles at air temperatures below -20 0 C, fractures often form in the places where the sole is bent.

Thermopolyurethane (TPU, TPU)

The above disadvantages are devoid of thermopolyurethane. The high-quality traction of the TPU soles provides a deep tread that can be molded thanks to the high density of the material. TPU soles are resistant to wear and deformation, they are not afraid of punctures and cuts.

The high density of thermopolyurethane is not only its advantage, but also a disadvantage, since TPU soles are not distinguished by high elasticity and thermal insulation properties, and they weigh decently.

The current situation is corrected by using a combined sole in the production of winter footwear, the layer in contact with the surface of which is made of thermopolyurethane, and the upper one is made of polyurethane.

Ethylene vinyl acetate (EVA, EVA)

The main advantage of EVA products is their lightness and elasticity. EVA soles are most often equipped with summer, indoor, children's and beach shoes. They are also used in the production of sports shoes as inserts that absorb impacts and evenly distribute the load over the entire foot.

During operation, the porous structure of EVA becomes denser and over time, EVA soles lose their shock-absorbing properties.

In winter shoes, ethylene vinyl acetate is not used due to poor adhesion to the surface and the instability of the material to low temperatures.

Polyvinyl chloride (PVC, PVC)

PVC differs from other materials in its increased wear resistance and high resistance to aggressive environments. If rubber is added to PVC, it becomes immune to the effects of engine oils and gasoline on it.

The cost of PVC is lower than all other materials used to make shoe soles.

The use of polyvinyl chloride is limited by its low frost resistance, therefore, the scope of its use is summer and demi-season shoes.

Rubber

Previously, rubber occupied a leading position among the materials for the production of footwear. And there were reasons for this, since this material is resistant to wear and deformation, is not afraid of temperature extremes, and is both durable and flexible at the same time.

Rubber is not afraid of either high or low temperatures, does not slip on ice.

At the same time, rubber soles have a decent weight and considerable cost, therefore, recently they are being replaced by products from lighter and cheaper materials.

Thermoplastic rubber (TPR, TPR)

This type of material for shoe soles is one of the varieties of synthetic rubber.

Thermoplastic rubber has high shock-absorbing properties, the absence of through pores in it makes this material waterproof, and the soles made of it differ from other products in their low weight.

TPR also has disadvantages: in frosty weather it slips, and its thermal insulation properties leave much to be desired.

Let your shoes, regardless of the sole material, be durable, comfortable and practical! Good luck with your choice!

Many people know that when choosing a shoe, the material of its manufacture plays a decisive role in making a decision. However, often only the upper is taken into account, and the sole is not paid attention to. This is not entirely true, because it is this part of the shoe that is most affected. The foot and the weight of a person presses on her from above, and the earth seeks to demonstrate its superiority from below. Therefore, the material of manufacture of this part must be reliable and comfortable to use. Consider the advantages and disadvantages of the materials used in the manufacture of shoe soles.

Polyurethane soles

Advantages: Polyurethane has good performance properties: it weighs little, since it has a porous structure, it resists abrasion well, is flexible, has excellent shock absorption and good thermal insulation. Soles made of polyurethane are lightweight and flexible, therefore they are used in footwear where these characteristics are of particular importance.

Disadvantages: The porous structure of polyurethane is also a kind of reverse side of the coin. For example, it makes the polyurethane sole have poor grip on snow and ice, so winter shoes with PU soles are very slippery. Also, the disadvantage is the high density of the material and the loss of elasticity at low (from -20 degrees) temperatures. This results in fractures in places where the sole is bent, the rate of appearance of which depends on the characteristics of the operation of the shoe, in particular, on the person's gait, the degree of his mobility and other factors.

Thermopolyurethane (TPU, TPU) soles

Advantages: TPU has a high enough density, so that it can be made of soles with deep tread, which provide excellent traction. Also, the advantages of TPU are high wear resistance and resistance to deformation, including cuts and punctures.

Disadvantages: The high density of thermopolyurethane is at the same time its disadvantage, because because of this, the weight of the thermopolyurethane sole is quite large, and the elasticity and thermal insulation leave much to be desired. To improve these characteristics, TPU is often combined with polyurethane, thereby achieving a reduction in sole weight, increasing its thermal insulation and elasticity. This method is called two-composition casting, and it is quite simple to recognize it: the sole made using this technology consists of two layers, and the upper layer is made of polyurethane (PU), and the lower one, in contact with the ground, is made of thermopolyurethane.

Thermoplastic elastomer soles (TPE, TRP)

Advantages: This material can be considered all-season. It is durable, elastic, frost and wear resistant. TPE provides good shock absorption and traction. Thanks to the technology of manufacturing the sole from TPE, its outer layer is monolithic, which provides it with strength, and the inner volume is porous and retains heat. Thermoplastic elastomer is recyclable, which means that its use in soles saves resources and does not pollute the environment.

Disadvantages: At high and very low temperatures (over 50 degrees and below -45 degrees), TPE loses its properties, therefore it is used only in everyday shoes.

Polyvinyl chloride (PVC, PVC) soles

Advantages: PVC soles resist abrasion well, are resistant to aggressive environments and are easy to manufacture. They are often used in indoor and children's shoes.

Disadvantages: PVC is used only in the production of casual shoes for autumn or spring, because this material has a large mass and low frost resistance, not withstanding temperatures below -20 degrees. In addition, PVC soles do not adhere well to leather uppers, so quality leather shoes with PVC soles are difficult and expensive to manufacture.

Ethylene vinyl acetate (EVA, EVA) soles

Advantages: EVA is a very light material with good shock-absorbing properties. It is used mainly in children's, home, summer and beach shoes, and in sports shoes - in the form of inserts, because it is able to absorb and distribute shock loads.

Disadvantages: Over time, EVA soles lose their cushioning properties. This is due to the fact that the pore walls are destroyed, and the entire mass of the EVA becomes flatter and less elastic. Also, EVA is not suitable as a material for winter shoes, since this material is very slippery and not resistant to frost.

Thermoplastic rubber (TPR, TPR) soles

Thermoplastic rubber is a shoe rubber made from synthetic rubber, which is stronger than natural rubber, but no less elastic. However, modern technologies make it possible with the help of various additives to increase its flexibility. Thanks to its qualities, such a sole relieves stress from the spine during long-term use.

Advantages: Thermoplastic rubber has a low density and, accordingly, less weight than other materials. There are no through pores in it, so moisture does not pass through it. However, there are surface pores in the TPR, and they provide high thermal protection. In addition, TPR, like other porous rubbers, is an elastic material that provides good shock absorption properties. Thanks to this characteristic, shoes with TPR soles relieve unnecessary stress on the legs and spine.

Disadvantages: The low density of the material can be not only an advantage, but also a disadvantage. In the case of TPR, it leads to the fact that the outsole of this material does not have particularly outstanding thermal protection properties. In addition, in wet and frosty weather, the thermoplastic rubber outsole is highly slippery.

Leather soles

Advantages: Leather soles are used in all types of footwear, including children's, home and fashion footwear of all seasons. Shoes with leather soles look great and allow the foot to breathe, as they are a natural membrane.

Disadvantages: When worn in wet weather, the leather sole can deform, and caring for it involves the constant use of special sprays and impregnations. Leather has a low wear resistance, therefore, it is recommended to install prophylaxis on leather soles, and it is mandatory for winter shoes, otherwise the sole will slide on ice and snow and deform even faster without it.

Tunit soles

Tunit is a rubber containing leather fibers, therefore the second name of this material is "leather fiber".

Advantages: In appearance, hardness and plasticity, tunite soles are similar to leather ones, but they behave better in operation: they hardly wear off and do not get wet. These soles are easy to emboss, giving them slightly more traction than leather.

Disadvantages: But even despite this, shoes with tunite soles are very slippery due to the high rigidity of the material. Therefore, tunit is used in the manufacture of only summer and spring-autumn shoes of the adhesive fastening method.

Wood soles

Advantages: Wood is an environmentally friendly and highly hygienic material, and wooden soles have an original look. However, recently, instead of wood, plywood has been used more often for making shoes. It can be made of birch, oak, beech or linden wood and, as a material, is easier to machine, molds well and is inexpensive. Cork soles are also popular. When dealing with them, one must understand that cork, due to its natural softness, cannot serve as the main material for the manufacture of soles, therefore, cork is used only for decorative covering.

Disadvantages: Wooden soles are tough, wear out quickly and have poor water resistance. A lot of material is consumed in the manufacture of such soles. Cork coverings are prone to chips and defects due to the softness of the material.

Rubber soles

Previously, it was the most common, because it showed itself well. However, the mass production forced manufacturers to use other materials that are more profitable from an economic point of view.

Advantages: This material is slip-resistant, durable, frost-resistant. Attaches well to leather upper.

Disadvantages: the multicomponent composition of the rubber sole and the complexity of the connection of the components, a large number of manufacturing operations in the manufacture of the material. At the same time, rubber soles are heavy and very easily soiled. Therefore, the cost of the material is quite high. It was this factor that forced manufacturers to use alternative materials.

This is what the most common shoe sole materials look like. Unfortunately, the ideal does not exist, however, certain species, with proper use, can manifest themselves exclusively on the positive side.

The main condition for light gait all day long is the right footwear. Going to the store, we definitely pay attention to the design of the boots, we are attentive to the choice of leather or suede, we measure the height of the heel, but we do not always look at the sole and the material from which it is made. And the quality of shoes depends a lot on this.

For example, shoes with TEP-soles have a number of indisputable advantages, such as durability, lightness, flexibility and ease of use. Inexpensive material is indispensable for both children's and adult shoes. It shows its best qualities both in winter and in summer, it allows you to feel comfortable on any irregularities in the road.

What is TPE?

Modern manufacturers regularly update the range of materials used to make shoe soles. One of the most recent solutions is thermoplastic elastomer, or TEP.

So, TEP sole - what is it? This material is created on the basis of thermoplastic rubber, which combines the best properties of thermoplastics and elastic rubber. Plastic and wear-resistant thermoplastic elastomer is the best solution for the manufacture of soles, both winter and It perfectly copes with high loads, allowing boots to last for more than one year, tolerates high and low temperatures well, and is resistant to chemicals.

Winter summer

The thermoplastic elastomer is easy to correct. The addition of polymers to the formula of the material in certain proportions makes it possible to create a TEP sole with varying degrees of elasticity for any season or load. Thus, technologists practically reach perfection - the most frost-resistant shoes for severe frosts or wear-resistant summer models are produced that do not hinder movement and are practically weightless. The TEP sole, reviews of which are overwhelmingly positive, is an undoubted advantage of the shoe.

Combined outsole

TPU-marked shoe soles are made on the basis of thermoplastic elastomer and polyurethane. The combination of durable and frost-resistant TPE and light and soft PU makes the material especially valuable. The TPE / PU outsole combines all the advantages of both materials, in addition, it is available in any color: from standard black to hot pink, blue and light green colors. This is especially important in the production of bright and beautiful children's shoes. Saturated colors do not fade in the sun, do not fade and last for many years.

The main advantages of polymer soles

The class of soles, which include certain polymers, has a number of indisputable advantages. It:

• Increased elasticity at the highest temperatures. The material does not shrink under the influence of sunlight, does not fade or deform.
• Excellent thermal stability at low and very low temperatures. In shoes with a TEP sole, you will be comfortable even in severe frosts, which winter often "pampers" us with.
• Resistance to acids, alkalis, various microorganisms. This is especially important in megalopolises, whose roads in winter turn into a crazy cocktail of salts and chemical elements that can ruin the most expensive and high-quality shoes.
• Good electrical insulating properties. They are important for those who work with electrical equipment.
• Increased strength and tear resistance. Even under aggressive conditions, the material will not crack or burst. In shoes with TEP-soles, you can walk on any surface: it is not afraid of gravel, sand or paving stones.

Main advantages

TEP sole - what is it? Surely this question was asked by every buyer of footwear created using a material that combines the most modern technologies and the ideas of each of us about comfortable, comfortable and durable footwear. Thermoplastic elastomer has a number of characteristics that speak in favor of the choice of boots, moccasins or boots from such a material. The TEP sole, reviews of which are mostly positive, pleases almost everyone. Buyers note:

• Exceptional lightness, which allows the leg to not get tired.
• The flexibility you need to move around comfortably.
• High wear resistance, which makes the shoes truly durable.
• Resistant to high and low temperatures
• Safety and environmental friendliness.

Winter shoes with TEP-soles

When choosing winter shoes, safety becomes one of the most important conditions. You need to feel confident even in the most unfavorable weather conditions. That is why it is important to know whether the TPE sole is slipping or not. Does not slip! Equipped with a raised protector, it avoids injury even in ice.

Another plus that speaks in favor of choosing winter shoes with a TEP-sole is frost resistance. The elastic material feels great in the most severe frosts, without cracking even at a temperature of -45 degrees. The TEP sole helps to keep the feet warm and dry in winter. You will be as comfortable as possible even when walking for hours in the snow or going to work on the autumn slushy streets. Shoes with TPE soles are a guarantee of your safety and confidence in any weather.

Summer and demi-season models

Choosing winter footwear, buyers ask: "Does the TEP sole slip or not?" But when choosing models for other seasons, the first place comes to the question of the wear resistance of shoes or boots in conditions of constant contact with the asphalt surface. TEP sole - what is it and how does it behave in summer? It is very flexible, so it absolutely does not hinder the movements of the foot. Lightweight and beautiful shoes will last more than one season without losing their original attractiveness, brightness and other properties.

The lightness of shoes with TPE soles is due to the fact that only the outer layers of the material are monolithic. The inner layers are porous, which means they are practically weightless. TPE (thermoplastic elastomer-sole) absorbs well when walking, allowing you to feel comfortable even with intense loads or uneven surfaces.

Children's shoes

Most often, children's boots or shoes have a sole - rubber or TPE. By opting for the latter option, you choose lightness, flexibility, frost resistance and durability. A small child is able to run a lot of kilometers in a day, which means that his legs should not get tired or sweat under any load. The most active baby will feel comfortable and cozy in high-quality shoes with thermoplastic elastomer soles, of course, provided that the correct size and good top of the boots or boots are used. Bright models will appeal to any fashionista or fashionista.

TEP sole material - what is it? How safe is it for a child of a given age? Does it cause allergic reactions? Such questions are asked by young mothers in many forums. Indeed, on how comfortable the child will be, it directly depends on how correctly the foot will be formed in the future. Reading reviews about children's shoes from TEP, one can come to the conclusion that it is absolutely safe and comfortable for any age, does not hinder movement, does not deform and does not cause any inconvenience during operation. Kids feel great in shoes with TEP-soles and on a walk in the winter park, and when playing on the children's summer playground. Legs do not slip, shoes do not hinder movement, do not weigh down the leg.

TEP sole is an affordable solution!

Thermoplastic elastomer is inexpensive, so footwear with a TEP sole is available for the budget of any family. The price of cozy and warm felt boots for a child, for example, is about 1000 rubles. The advantage of such shoes is not only in savings when buying, but also in the possibility of long-term operation, since felt boots are worn for a really long time, without deforming at low temperatures and constant loads. Moreover, the quality of the material is much higher than its cost. Today, many global footwear manufacturers opt for thermoplastic elastomers. This allows you to significantly reduce the cost of products, and therefore attract new grateful buyers. This is especially true for children's shoes, which have to be bought more often than adults, and the price really matters.

Other types of sole materials

Among the most popular materials used for the production of soles of children's and adult footwear today are the following: rubber, leather, rubber, polyvinyl chloride. Each has a number of advantages and disadvantages. For example, a leather sole allows the foot to breathe, but it does not boast of wear-resistant properties. In addition, leather is a rather expensive option, often used for luxury footwear. For everyday wear, as a rule, shoes with more practical soles are used, which are no less beautiful and safe.

Used in the manufacture of soles and natural wood or plywood. Such material is as environmentally friendly as possible. However, it wears out rather quickly, is easily exposed to moisture and chemicals.

Rubber is a cheap material, but rather capricious, reacting negatively to the effects of low and high temperatures. In addition, such shoes slip a lot, which is unacceptable in our harsh winter and traditionally slippery roads.

Another thing is the material of the TPE sole. What is it? This is a combination of all the qualities necessary for durable and comfortable footwear. Comfortable, lightweight and high-quality sole will make any model truly beloved and regularly worn.

Environmental friendliness

Above, we talked about what characteristics the TEP sole has. quality, lightness, durability, etc. However, the advantages do not end there. Today, when every schoolchild is aware of environmental problems, concern for nature comes first. Thermoplastic elastomer is one of the few modern materials that can be recycled, which means it does not pollute the environment. This property of the material will surely attract the attention of everyone who cares about the health of their own and future generations. Choosing shoes with TPE soles, you choose high quality and environmental friendliness at the most affordable price.

Disadvantages of TPE-soles

Despite the many indisputable advantages, there are also some disadvantages. This is the inability of the material to withstand temperatures above +50 and below -45 degrees. Of course, in terms of everyday wear, such characteristics are not very important. Agree, the weather rarely surprises with such phenomenal temperatures. However, for example, for an employee of the metallurgical industry who visits hot workshops every day, such a sole will not work.

Considering that extreme temperatures are rare, this disadvantage can be considered insignificant and does not play a big role in the choice. Shoes with TPE soles are a great option for everyone who wants to purchase a high quality product at an affordable price!

It is very difficult, without preparation, to make the right choice in the variety of assortment of a sex shop. A beginner, first time getting into an intimate store, inevitably gets lost among the different-sized boxes with bright pictures, dildos, vaginas and other products.

To begin with, we would like to talk about the materials used for the production of sex products.

Manufacturers take into account the fact that their products come into contact with the most delicate and delicate parts of the human body, and this imposes increased requirements on the materials used. Besides the fact that they must be harmless to health, they must also be tactilely comfortable and visually attractive.

So, the following materials are mainly used in the production of sex products:

Most economical material - polyvinyl chloride(PVC) - smooth, harsh, cold to the touch, but elastic. PVC is used by domestic sex toy manufacturers. The quality of polyvinyl chloride depends on the technology of its production and is determined by the degree of elasticity, smell and strength during operation.
