Polyurethane elastomer is a new polymer synthetic material between rubber and plastic. It has the high strength of plastic and the high elasticity of rubber. Features include:
It still has the elongation and resilience of rubber under high hardness. The hardness range of polyurethane elastomer is Shore A10-D80.
At the hardness of rubber, its breaking strength and load-bearing capacity are much higher than ordinary rubber. At high hardness, its impact strength and bending strength are much higher than those of plastic. Its wear resistance is very excellent, generally in the range of 0.01-0.10 (cm3)/1.61km, which is about 3-5 times that of rubber.
Polyurethane elastomer is a highly polar polymer compound with little affinity for non-polar mineral oils and is almost non-corrosive in fuel and machinery oils. Good oxygen resistance and ozone resistance.
It has excellent vibration-absorbing properties and can be used as a vibration-absorbing and buffering material. In the mold manufacturing industry, it replaces rubber and springs. It has good low temperature performance. Polyurethane has good resistance to high-energy rays and still has satisfactory performance under a radiation dose of 10-10ge. Good machining properties.
