SILIKE Si-TPV is a patented dynamic vulcanized thermoplastic silicone-based elastomer made by a special compatible technology and dynamic vulcanized technology to help silicone rubber dispersed in TPU evenly as a 2~3 micron particles under microscope and forms a special island structure, solves the problem of TPU and silicone incompatibility. Its performance is far better than common thermoplastic vulcanizate (TPV) or other thermoplastic elastomer, with low hardness of silicone rubber, high and low temperature resistance, chemical resistance, high resilience and TPU outstanding mechanical strength, good biocompatibility, etc. It can be co-extruded with many thermoplastic engineering plastics like PC, ABS, PVC and double-color injection molding. It is widely used in many fields such as smart watch band, wrist band, phone cases, wires, plastic wraps,etc. It gives good coating and high body feeling performance, and wont need softening oil, solves precipitation problem from the source.
