Polyurethane elastomer is a new type of polymer material between rubber and plastic, high strength, it has both plastic and has the high elasticity of rubber
.,0.01-0.10(cm³)/1.61km,3-5.
Wear-resisting. The wear resistance is very outstanding, generally in the 0.01-0.10 (cm ³)/1.61km range,is about 3-5 times of rubber.
.,,.
Oil resistant. Polyurethane elastomer is a kind of strong polar polymer compound, and the affinity of non-polar mineral oil in small, fuel oil and lubricating oil is almost not affected by erosion.
