hard urethane 95A rubber roller wheels Factory direct sales
Polyurethane elastomer is a new type of polymer composite material between rubber and plastic. It has both the high strength of plastic and the high elasticity of rubber.
DECAI urethane rubber roller wheels features:
1. Wide range of hardness. It still has the elongation and resilience of rubber at high hardness. The hardness range of polyurethane elastomers is Shore A10-D80.
2. High strength. Their tear strength and load-carrying capacity are much higher than general-purpose rubbers at rubber hardness. At high hardness, its impact strength and bending strength are much higher than that of plastic.
3. Wear-resistant. Its wear resistance is very outstanding, generally in the range of 0.01-0.10 (cm3)/1.61km, which is about 3-5 times that of rubber.
4. Oil resistance. Polyurethane elastomer is a kind of strong polar polymer compound, which has little affinity with non-polar mineral oil, and is hardly corroded in fuel oil and mechanical oil.
5. Good resistance to oxygen and ozone.
6. Excellent vibration absorption performance, can be used for vibration reduction and buffering. In the mold manufacturing industry, it can replace rubber and springs.
7. Has good low temperature performance.
8. Radiation resistance. Polyurethane has good resistance to high-energy rays, and still has satisfactory performance under the radiation dose of 10-10 g.
9. Has good machinability. (turning, milling, grinding, drilling can be used)
