TPU (Thermoplastic polyurethanes) is a 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, sporting goods, toys, decorative materials and other fields. It has no halogen resistance. Burnt TPU can also replace soft PVC to meet environmental protection requirements in more and more fields.
The so-called elastomer refers to a polymer material with a glass transition temperature lower than room temperature, an elongation at break >50%, and good recovery properties after external force is removed.
Polyurethane elastomer is a special category of elastomers. Polyurethane elastomer has a wide hardness range and a wide performance range. Therefore, polyurethane elastomer is a type of polymer material between rubber and plastic. It can be heated and plasticized, and has no or little cross-linking in its chemical structure. Its molecules are basically linear, but there are certain physical cross-links. This type of polyurethane is called TPU.
