The Characteristics of Polyurethane Sheet

The Characteristics of Polyurethane Sheet

1. Wide range of hardness. It still has the elongation and resilience of rubber at high hardness. The hardness range of the polyurethane sheet is Shore A10-D80.

2. High strength. Their tear strength, tear strength and load-carrying capacity are much higher than general purpose rubbers at rubber hardness. At high hardness, its impact strength and flexural strength are much higher than those of plastics.

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 board 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 oxygen and ozone resistance.

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 and drilling are acceptable).
