With the improvement of the manufacture and technology of the products and the widening of the application field, the polyurethane material has gradually become the sixth largest synthetic material in the world (PE, PP, PVC, PS, PET, PU). At present, China has become the fastest developing market center of polyurethane in the world. Polyurethane products account for 30% of the total amount of the world. Some of China's polyurethane products such as PU leather, PU sole, polyurethane and TPU (thermoplastic polyurethane elastomer) have leaped the first place in the world. BASF, Bayer, Humtsman and other world-famous multinational companies have built the world-class polyurethane base raw material production base and the global polyurethane research center in China. Although the global financial crisis has a great impact on the polyurethane industry in developed countries such as Europe and America, the polyurethane industry will continue to develop steadily and promote the development of the global polyurethane industry under the incentive of domestic demand and other related policies.
