TPU (Thermoplastic polyurethanes) is called thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type. It has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency, and good elasticity. It is widely used in daily necessities, sporting goods, toys, decorative materials, etc. Halogen-free flame-retardant TPU can also replace soft PVC to meet environmental protection requirements in more and more fields. The so-called elastomer refers to the polymer material with glass transition temperature lower than room temperature, elongation at break>50%, and better recovery after external force is removed. Polyurethane elastomer is a relatively special category of elastomers. Polyurethane elastomers have a wide range of hardness and performance. Therefore, polyurethane elastomers are a type of polymer material between rubber and plastic.
