TPE:thermoplastic elastomer is also called TPR:thermoplastic rubber. Because it can be processed like plastic at high temperature, and at room temperature, it shows the unique high elasticity of rubber. Compared with rubber, it does not need time-consuming and energy-consuming vulcanization process, and the processing cost is significantly reduced. It is generally believed that the thermoplastic elastomer is a phase separation system. At room temperature, one of the phases is a hard polymer (hard segment). With the characteristics of easy processing, light specific gravity, recyclable and environmental protection and halogen free, it can be processed in the traditional thermoplastic forming machinery, no special equipment and skills are required; The other phase is rubber phase (soft segment). Make it a substitute of traditional rubber and PVC.
