Polyurethane Elastomer

Since the early 1980s, polyurethane elastomers have been transformed from military use to military and civilian use, and have been mainly used for civilian use. The varieties and brands of products have been increasing, and the scale of production has been expanding. It has played a role in various sectors of the national economy and people's clothing, food, housing and transportation. increasingly important role.

Polyurethane elastomer is a variety of polyurethane synthetic materials. Because its structure has two segments, soft and hard, it can be molecularly designed to endow the material with excellent properties such as high strength, good toughness, wear resistance, and oil resistance. It has both The high elasticity of rubber has the rigidity of plastic, which is called "wear-resistant rubber".

Polyurethane elastomers can be molded by plasticizing, kneading and vulcanization processes (refer to MPU) like general-purpose rubbers; they can also be made into liquid rubber, cast molding or spraying, potting, centrifugal molding (referring to CPU); Pellet material, like ordinary plastic, is formed by injection, extrusion, calendering, blow molding and other processes (referring to CPU). Molded or injection molded parts can also be processed by cutting, grinding, drilling and other machining within a certain hardness range. The diversity of processing makes the applicability of polyurethane elastomers very wide, and the application fields continue to expand. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound permeability, strong adhesion, excellent biocompatibility and blood compatibility. These advantages are the reason why polyurethane elastomers are widely used in military, aerospace, acoustics, biology and other fields.
