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. Its characteristics are: Wide hardness range. It has the elongation rate and resilience of rubber under high strength. The hardness range of polyurethane elastomers is Shore A10-D80. high strength. Their tear strength and load-bearing capacity are much higher than ordinary rubber at rubber hardness. Under high hardness, its impact strength and bending strength are much higher than those of plastic. Wear resistant. Its wear resistance is very good, generally in the range of 0.01-0.10 (cm3)/1.61km, which is about 3-5 times that of rubber. Oil resistant. Polyurethane elastomer is a highly polar polymer compound that has little affinity with non-polar mineral oil and is almost not corroded by fuel oil and mechanical oil. Good oxygen and ozone resistance. It has excellent shock absorption performance and can be used for shock absorption and buffering. In the mold manufacturing industry, it replaces rubber and springs. Has good low temperature performance; Radiation resistance. Polyurethane has good resistance to high-energy rays and still has satisfactory performance under a radiation dose of 10-10 Ge. Has good machining properties.
