Product Tips:
Polyurethane is a new polymer synthetic material different from rubber and plastic. It not only has the high strength of plastic but also the high elasticity of rubber. Its characteristics are very remarkable, for example, it has a wide range of hardness, and it still has the elongation and resilience of rubber at high hardness. The strength of polyurethane is also very high. Under the hardness of rubber, their breaking strength and load-bearing capacity are much higher than that of general-purpose rubber. Under high hardness, its impact strength and bending strength are much higher than plastics.
Polyurethane elastomer can be made into liquid rubber, casting and compression molding (referring to CPU). Molded parts can also be machined for cutting, grinding, drilling, etc. within a certain hardness range. The diversity of processing makes the applicability of polyurethane elastomers very wide, and the application fields continue to expand.
