TPU (Thermoplastic polyurethanes), thermoplastic polyurethanes, the oligomer is a polyol soft segment and a diisocyanate - linear block copolymer chain extender hard segment constituted.
　　In recent years, due to the continuous development of new products, the amount of the thermoplastic elastomer TPU is continuing to increase, in order to create a low-cost plastic processing industry, industry of new high value-added opportunities.
　　TPU (thermoplastic polyurethane) because of its superior performance and environmental concept increasingly popular. Currently, any local use of PVC, TPU can become the alternative to PVC.

　　TPU film is based on the TPU pellets were salivation, blown film, calendering or coating made of a thin film, with good elasticity, toughness, abrasion resistance, cold resistance, nontoxic superior characteristics. It was first widely used in sports shoes: shoe soles and on the trademark decoration, balloon, air, oil and other packages. Then there are the women sandals, women's underwear by popular wind blowing, that is highly transparent TPU films or direct cut, or screen printing color, or fitting into a folder mesh cloth and other decorative effect.
