TPE, TPV and TPU belong to the same category, collectively known internationally as thermoplastic elastomer, abbreviation: TPE

　　As for the usual TPE, it is made of SEBS, SBS + PP + naphthenic oil + calcium carbonate + additives blend, also known as environmentally friendly soft plastics in the industry; TPV is PPEPDM as the main base material of elastomer, dynamic vulcanization; TPU, also known as polyurethane, there are polyester and polyether type two.

　　TPE, TPV TPU material comparison of the three.

　　1, transparency, TPU is better than TPE, TPE is better than TPV, TPV in the market has not yet appeared transparent, but it is said that a large foreign company has developed this type of product.

　　2, weather resistance, TPV is better than TPE, TPE is better than TPU.

　　3, specific gravity, the specific gravity of TPE varies greatly, from 0.89 to 1.3, TPV in about 0.98, TPU in 1.0 to 1.4 (reference: the specific gravity of water is 1).

　　4, wear resistance, TPU is better than TPV, TPV is better than TPE, there are also highly wear-resistant TPE, but there is still a bit of a gap with TPU.

　　5, oil resistance, TPU (good) better than TPV (medium), TPE is not oil resistant.

　　6, acid and alkali resistance (weak acid and alkali), TPV is better than TPE, TPU is not acid and alkali resistance.

　　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.
