TPU (Thermoplastic polyurethanes) name for a thermoplastic polyurethane elastomer rubber. Divided into polyester and polyether type of points, it is a wide range of hardness (60HA-85HD), abrasion resistance, oil resistance, transparency, flexibility, and in the areas of daily necessities, sporting goods, toys, decorative materials are widely used, Halogen-free flame retardant TPU can also replace the soft PVC to meet increasing environmental requirements in many fields.

It refers to the so-called elastomer glass temperature below room temperature, elongation at break> 50%, after removal of the external force better resilience polymer material. Polyurethane elastomer is an elastomer in a rather special category, polyurethane elastomer hardness range is very wide, very wide range of properties, so the polyurethane elastomer is between a class of rubber and plastic polymer materials.

Heatable plastics, chemical structure with little or no cross-linking molecule is substantially linear, but it has certain physical crosslinking exist. Such polyurethane called TPU
