HTPVSi is a kind of silicone rubber thermoplastic elastomer which is easy to process and shape. Compared with ordinary thermoplastic elastomer, HTPVSi has more excellent coating and unique human aesthetic touch, and has excellent mechanical properties, wear resistance, high and low temperature resistance. Performance characteristics: good mechanical properties, wear resistance, high and low temperature resistance, processability and silky touch, recyclable, green environmental protection. Excellent adhesion to polar substrates such as PC, ABS, nylon or non-polar substrates such as PE and PP.
