Introduction of Polyurethane |

Polyurethane synthetic material is one of the materials with the fastest growing speed in recent decades. Its industrialized production is carried out mainly through the reaction between organic polyisocyanate and polyols. Polyurethane products with different performances and manifestations can be achieved by selecting different numbers and types of functional groups, and adopting different synthesizing technologies, from very soft foam to extremely rigid foam, from highly wearproof elastomer, painting and coating with high glossiness, to highly elastic synthetic fibers, highly anti-bending synthetic leather, highly cohesive adhesive, and so on. Thus, a new-type synthetic material series with great varieties and excellent performance is gradually formed. With the continuous expansion of production application, this kind of polymer has become an essential material for applications from aviation aircraft to industrial and agricultural production, from recreation and sports facilities to daily necessities such as clothing, food, shelter, traveling etc. Currently, the adoption of polyurethane materials is very popular among developed countries in Europe and the U.S. The consumption of polyurethane in China is also increasing rapidly. With its excellent performance and environmental protection and safety features, polyurethane is playing a more and more important role in such areas as building, vehicle, aviation, medical treatment etc.
