- Dec 02, 2017 -

1. Suitable mechanical strength and hardness;

2. The material density is good, it is not easy to leak the medium.

Three. The compressibility and resilience are good, and the permanent deformation is small.

4. It has good corrosion resistance and can work in the medium of acid, alkali and oil for a long time, and its volume and hardness change little, and it is not attached to the metal surface.

5. Do not soften under high temperature, do not break down, do not harden at low temperature.

6. The friction coefficient is small, and the wear resistance is good.

7. Soft combination cover;

8. The processing and manufacturing profit is low, the price is cheap, and the use is convenient.

9. Good aging resistance and durability;
