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 seals material is as follows:
1. Has a certain mechanical properties such as tensile strength, elongation, etc.
2. The elasticity and appropriate hardness, compression permanent deformation small.
3. The high temperature and low temperature resistance, high temperature decomposition, softening, low temperature not hardening.
4. To adapt themselves to the working medium, do not produce swelling, decomposition, hardening, etc.
5. The oxygen resistance and aging resistance, durable.
6. Wear resistance, no corrosion metal.
7. Forming easily, the price is low.
