First, let's look at polyurethane rubber. Polyurethane rubber is a kind of polymer material formed by the interaction between polyurethane prepolymer and rubber molecular chain. It has excellent properties such as adjustable hardness, wear resistance, oil resistance, high temperature resistance and high elasticity, so it has a wide range of applications in various fields.
Polyurethane rubber has extremely high strength and elasticity. Compared with traditional natural rubber, polyurethane rubber has much higher strength and elastic modulus, which makes it maintain good shape and performance even under high load.
Polyurethane rubber has excellent oil resistance. The carbamate group contained in its molecular structure makes it have good resistance to non-polar solvents, so it can maintain good stability in various oils and lubricants.
In addition, polyurethane rubber also has excellent high temperature resistance. It has a wide range of heat-resistant temperatures and can maintain its physical properties at high temperatures, so it is widely used in sealing and shock absorption in high temperature environments.
So, in what fields has polyurethane rubber been applied? In fact, it has a wide range of applications. In the field of sporting goods, polyurethane rubber is used to manufacture the soles of various sports shoes to provide good elasticity and cushioning effect. In the field of medical equipment, polyurethane rubber is used to manufacture various medical pipes, seals, etc., to provide good biocompatibility and durability.
In the field of transportation, polyurethane rubber is widely used in the manufacture of various seals, shock absorbers, etc., to improve the performance and stability of equipment. In the electronic and electrical field, polyurethane rubber is used to manufacture various cable insulation layers, battery seals, etc., to provide good electrical performance and durability.
