Transparency
TPU is better than TPE, TPE is better than TPV, and TPV has not been transparent in the market, but it is said that large companies in foreign countries have developed such products.
2. Weather resistance
TPV is superior to TPE, and TPE is superior to TPU.
3. Specific gravity
The specific gravity of TPE varies widely, from 0.89 to 1.3, TPV is around 0.98, and TPU is between 1.0 and 1.4 (reference: water specific gravity is 1).
4. Abrasion resistance
TPU is better than TPV, TPV is better than TPE, and there is also a high wear-resistant TPE, but it is still a bit different from TPU.
5. Oil resistance
TPU (good) is better than TPV (medium), TPE is not oil resistant.
6. Acid and alkali resistance (weak acid and weak base)
TPV is superior to TPE, and TPU is not resistant to acid and alkali.
7. Temperature resistance
The TPE is -60 ° C ~ 90 ° C, the TPV is -60 ° C ~ 130 ° C, and the TPU is -60 ° C ~ 80 ° C.
Application range of TPU, TPE and TPV
Application area of TPU
Automotive industry
Because TPU has good mechanical properties, it is resistant to oil, grease, high and low temperature, elastic and wear resistant. It has now been applied more and more to the automotive industry. For example, brake pipes, oil pipes, emergency airbags, interior trims, and the like.
2. Cable
TPU provides tear, abrasion and bending resistance. Resistance to high and low temperatures is the key to cable performance. In addition, it is resistant to chemicals, hydrolysis and microbial decomposition, and easy to process and dye. Therefore, high-grade cables such as control cables and power cables use TPU to protect the coated materials of complex cables and their applications are becoming more widespread.
3. Pipe
TPU has flexibility, crack resistance, good memory, and is not easy to twist and return to its original shape in a wide temperature range. It can be welded, oil-resistant, chemical-resistant, and grease-resistant, making it the latest generation of high-grade pipe, which can be made into oil pipes, water pipes, compressed air pipes, pneumatic components and air compressors.
4. Shoes and exercise equipment
TPU is the fourth generation of sole material after rubber, PVC and SBS. It has greater elasticity and better mechanical strength, and has better wear resistance, crack resistance, bendability and stronger friction. It has become a highly demanding special shoe sole and upper. Materials, such as football shoes, skate shoes, hiking shoes, work shoes, etc., can also be used for soccer, handball, basketball, volleyball spherical materials and auxiliary materials for various sports equipment.
5. Shaped materials
Since TPU materials can be processed into various shapes by plastic processing methods such as injection molding, extrusion, calendering, etc., various high-grade decorative lines of oil resistance, high temperature resistance, aging resistance and high mechanical properties are exerted by TPU materials and TPE materials. Application areas for superior performance. In particular, the high elasticity of thermoplastic elastomers is not affected by oil, high temperature water and harsh environment, and has become the material of choice for high-grade decorative lines, sealing strips, and soft and hard decorative strips.
TPV performance and application areas
The structural characteristics of TPV not only ensure its good thermoplastic rheology, but also easy to shape and process. It can be molded by injection molding, extrusion, calendering, etc., and its high elastic energy at normal temperature. It is suitable for the sealing of various industrial equipment. Parts, shock absorbers, protective baffles and various special purpose pipes, fittings, etc.
TPE performance and application areas
TPE has the ozone resistance, weather resistance, aging resistance of PVC, crosslinkability of NBR (nitrile rubber), and improved tensile strength, tensile stress, tear resistance, heat resistance and flame resistance. It also has comprehensive properties such as oil resistance, fuel resistance, chemical resistance and easy coloring. Moreover, the main material PVC is rich in source and low in price, so it is widely used in many fields.
Wire and cable
TPE can be used in the electric cable industry, and can compete with TPU and TPV in the fields of special cables and submarine cables.
2. Hose
TPE can be used as a hose material, especially oil resistant hoses and gas hoses. Direct extrusion molding, fast speed, small expansion ratio, smooth and black surface, good tube blank and easy to control. Products have been tested and used by customers and generally reflect better.
3. Rubber roller
The rubber roller is a rubber core which is processed by a certain process. Due to the slight elastic deformation of the rubber layer on the surface of the rubber roller, the product is subjected to a certain pressure, adapts to the needs of the processing technology, and does not cause excessive shear stress to damage the product, and has a wide range of uses. For a long time, rubber rollers have mostly used rubber as an outer covering material. TPE replaces rubber for the production of rubber rollers, especially for light-colored, colorful rubber rollers, such as latex gloves production lines, printing, printing and dyeing, rubber rollers required by the textile industry.
4. Sole material
Like the TPU, TPE is the latest generation of sole material. Not only oil resistance, solvent resistance, flex crack resistance and wear resistance, but also cheaper than TPU, it has become a shoe with high performance and price ratio.
5. Other
In addition, TPE can also be used in the production of foams, protective coatings, flame-retardant conveyor belts, various profiled materials, soft and hard-bonded decorative and high-grade decorative strips.
