Features of heavy-duty polyurethane coated wheels
1. Hardness range. It still has the elongation and resilience of rubber under high hardness. The hardness range of polyurethane elastomer is Shore A10-D80.
2. High strength. Their tear strength, tear strength and load-carrying capacity are much higher than general rubber under the hardness of rubber. Under high hardness, its impact strength and bending strength are much higher than plastic.
3, wear resistance, its wear resistance is very outstanding, generally in the range of 0.01-0.10 (cm3) / 1.61km, about 3-5 times that of rubber.
4. Oil resistant. Polyurethane elastomer is a kind of strong polar polymer compound, and it has little affinity with non-polar mineral oil, and it is hardly corroded in fuel oil and machine oil.
5. Good resistance to oxygen and ozone.
6. Excellent vibration absorption performance, which can be used for vibration reduction and buffering. In the mold manufacturing industry, it replaces rubber and springs.
7. It has good low temperature performance.
8. Radiation resistance. Polyurethane has good resistance to high-energy rays and still has satisfactory performance under 10-10 Ge radiation doses.
9. It has good machinability (car, milling, grinding, drilling all possible).
