TPE TPV TPU belongs to the same category and is collectively referred to as thermoplastic elastomer in the world. The English abbreviation: TPE is a plastic raw material.
As for the commonly mentioned TPE, it is made of SEBS/SBS+PP+ naphthenic oil + calcium carbonate + additives. It is also called environmentally friendly soft plastic in the industry; TPV is an elastomer with EPDM as the main substrate, which is dynamically vulcanized. TPU, also known as polyurethane, is available in both polyester and polyether.
Comparison of the three:
1, transparency, TPU is better than TPE, TPE is better than TPV, TPV has not appeared transparent in the market, but it is said that large foreign companies have developed such products;
2, weather resistance, TPV is better than TPE, TPE is better than TPU;
3, specific gravity, TPE specific gravity varies widely, from 0.89 to 1.3, TPV is around 0.98, TPU is between 1.0 and 1.4 (reference: water specific gravity is 1);
4, wear 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 little 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 weak base), TPV is better than TPE, TPU is not resistant to acid and alkali;
7, temperature resistance, TPE is -60 degrees Celsius ~ 90 degrees Celsius, TPV is -60 degrees Celsius ~ 130 degrees Celsius, TPU is -60 degrees Celsius ~ 80 degrees Celsius.
