        Tpu (thermoplastic polyurethane elastomer rubber)

        TPU (Thermoplastic polyurethanes) is a thermoplastic polyurethane elastomer rubber. (60HA-85HD), wear-resistant, oil-resistant, transparent, good elasticity, in the daily necessities, sporting goods, toys, decorative materials and other fields are widely used, Halogen-free flame retardant TPU can also replace the soft PVC to meet more and more areas of environmental requirements.

        The so-called elastomer refers to the glass transition temperature is lower than the room temperature, elongation at break> 50%, external recovery after recovery is better polymer materials. Polyurethane elastomers are a special category of elastomers. The polyurethane elastomers have a wide range of hardness and a wide range of properties. Therefore, polyurethane elastomers are a kind of polymer material between rubber and plastic.

        Can be heated plasticized, chemical structure is not or rarely cross-linked, the molecules are basically linear, but there is a certain physical cross-linking. This type of polyurethane is called TPU.
