Chi Mei thermal plastic elastomer is a copolymer of styrene, and bitadiene. its linear and radical molecular has made it the characteristic of general rubber. Such as elasticity, adn physial charater but without vulcanizatiun. And its middle section is rubber phase, which contributes excellent elasticing, flow ability during processing, cold-resistane and can be injected like thermal-plastics. It is widely appied on sole,toys,asphale modifier instrument handle, and adhesives.
