Mechanical seal on the material performance requirements

The performance of the mechanical seal material is an important factor to ensure the mechanical seal. Mechanical seal material selection, mainly according to the mechanical seal components work environment, such as using temperature, working pressure, the working medium used as well as the movement way and so on. The basic requirements of mechanical seal material is as follows: 1. Has certain mechanical properties such as tensile strength, elongation, etc. ; 2. Flexible and appropriate hardness, compression permanent deformation small; 3. Not resistant to high temperature and low temperature, high temperature decomposition, softening, low temperature not hardening; 4. To adapt themselves to the working medium, do not produce swelling, decomposition, hardening, etc; 5. Oxygen resistance and aging resistance, durable; 6. Wear resistance, no corrosion metal; 7. Easy to forming, the price is cheap.
