Apply to become a distributor, can purchase from one piece TPU (Thermoplastic Polyurethane) is referred to as thermoplastic polyurethane elastomer rubber. It is mainly divided into polyester type and polyether type. It has a wide hardness range (60HA-85HD), is wear-resistant, oil-resistant, transparent, and has good elasticity. It is widely used in daily necessities, sports goods, toys, decorative materials, and other fields. Halogen-free flame-retardant TPU can also replace soft PVC to meet the requirements of more and more fields. The so-called elastomer refers to having a lower glass transition temperature than room temperature and high elongation at break50%, a high molecular material with relatively good resilience after external force removal. Polyurethane elastomers are a special category among elastomers. Polyurethane elastomers have a wide range of hardness and performance, making them a type of polymer material that lies between rubber and plastic. It can be heated and plasticized without or with few crosslinks in its chemical structure; its molecules are basically linear but exhibit certain physical crosslinking. This type of polyurethane is called TPU. null null
