1. High strength. Under the hardness of rubber and plastic, their tensile strength and bearing capacity are much higher than those of general rubber. Under high hardness, the impact strength and bending strength are much higher than those of plastics.
2. Wear resistant. Its wear resistance is very outstanding, generally in the range of 0.01-0.10 (cm3) / 1.61km, about 3-5 times of rubber.
3. Oil resistant. Polyurethane elastomer is a kind of strong polar polymer compound, which has little affinity with non-polar mineral oil and is hardly eroded in fuel oil and machine oil.
4. Good resistance to oxygen and ozone.
5. It can be used as shock absorber and buffer.
