Advantages of Polyurethane Lining

Advantages of Polyurethane Lining

Polyurethane lining has the following advantages:

1. It has good resilience performance, so it has less damage to the grinding medium.

2. Wide range of hardness. It still has the elongation and resilience of rubber at high hardness, and the hardness range of polyurethane elastomer is Shore A10-D95.

3. A very good feature is that its purity is very high, it does not contaminate the sample, and the wear is very, very small. Even if there is such a small amount of wear, it can be completely burned off in the later heat treatment and will not remain in the material.

4. The surface finish of polyurethane is one of the best among all materials. The non-stick wall of polyurethane depends on the elasticity and smoothness of its surface. The material cannot adhere to its surface, so as to obtain precise grinding.

5. Wear-resistant. Its wear resistance is very outstanding, generally in the range of 0.01-0.10(cm)/1.61km, which is about 3-5 times that of rubber.

6. Polyurethane oil resistant. 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.

7. Polyurethane has good oxygen and ozone resistance 

8. Excellent vibration absorption performance, can be used for vibration reduction and buffering. In the mold manufacturing industry, it can replace rubber and springs.

9. Has good low temperature performance.

10. Radiation resistance. Polyurethane has good resistance to high-energy rays, and still has satisfactory performance under the radiation 

dose of 10-10 g.
