Let's take a closer look at the material requirements of the mechanical seal.

1. The material has good compactness and is not easy to leak the medium;

2. Have proper mechanical strength and hardness;

3. Good compressibility and resilience, and small permanent deformation;

4. Does not soften and decompose at high temperatures, does not harden and does not crack at low temperatures;

5. Good corrosion resistance, can work for a long time in acid, alkali, oil and other media, its volume and hardness change is small, and it does not adhere to the metal surface;

6. Small friction coefficient, good abrasion resistance;

7. Has the softness combined with the sealing surface;

8. Good aging resistance and durable;

9. Convenient processing and manufacturing, cheap price and easy material collection.
