What is the difference between TPV and TPE

What is the difference between TPV and TPE?

Since TPE is a new type of environmentally friendly elastomer, many users are confused when they search for information on Baidu. What is the difference between TPE and TPV? TPE and TPV are both environmentally friendly and non-toxic thermoplastic elastomer materials. The following is a discussion of the differences between them by the author of Su Bo.

is the general term for thermoplastic elastomers. TPV is only one of TPE, which includes TPV, SEBS, TPO, POE, etc. TPE is a material made of SEBS as a base material and other mixtures. It has the high elasticity of rubber and the thermoplastic material of plastic. It is soft to the touch, weather-resistant, fatigue-resistant and temperature-resistant, with excellent processing performance and no need for vulcanization.

Thermoplastic vulcanizate (Thermoplastic Vulcanizate in English), referred to as TPV, is also called polyolefin alloy thermoplastic elastomer, an elastomer mixed with PP + EPDM. TPV is an environmentally friendly, low-carbon composite material that has the characteristics of rubber (high elasticity, compression permanent deformation, etc.) and the processing characteristics of plastic (simple process). It has good elasticity and resistance to compression deformation, and its environmental and aging resistance are equivalent to that of EPDM. Its oil and solvent resistance is comparable to that of general-purpose chloroprene rubber.

Differences between TPE and TPV:

1. TPV is a thermoplastic dynamically vulcanized rubber, while TPE is a thermoplastic elastomer. However, unlike SEBS-based elastomers, TPV is classified as a rubber elastomer.

2. TPV has better heat resistance than TPE. Generally, TPE can withstand high temperatures between 130 and 150 degrees Celsius! If it is higher, it will age and crack! ! It is recommended to use it below 120 degrees Celsius! ! TPV can be used normally at -60℃ to +135℃. When not under load, the high temperature resistance can reach +150℃

3. TPV has better aging and weather resistance than TPE, and the material of TPV sealing strip has a longer service life.

The hardness range of TPE is 0A-120A, and the hardness range of TPV is 25A-120A (70D). Compared with TPV, TPE has a wide range of hardness and hardness, and can reach a minimum of 0A ultra-softness, so ultra-soft TPE is often used in the adult products industry.
