Si-TPV®3100-75A Thermoplastic Elastomer
describe:
SILIKE Si-TPV thermoplastic elastomer is a dynamic vulcanized thermoplastic silicone-based elastomer which made by a special compatible technology to help silicone rubber dispersed in TPU evenly as a 2~3 micron particles under microscope. Those unique materials combine the strength, toughness and abrasion resistance of any thermoplastic elastomer with desirable properties of silicone: softness, silky feel, UV light and chemicals resistance which can be recycled and reused in traditional manufacturing
processes.
