[0002] Thermoplastic elastomer refers to a type of elastomer that has the elasticity of rubber at room temperature and can be plasticized and molded at high temperatures. It is a general term for materials such as TPR, TPU, TPV, TPEE, TPO, and TPAE.

[0003] When recycling thermoplastic elastomer materials, it is necessary to crush the thermoplastic elastomer materials. Thermoplastic elastomer materials are a type of thermoplastic soft rubber materials that have rubber elasticity and can be directly processed and molded without vulcanization.
