The basic requirements of mechanical seal materials:

The basic requirements of mechanical seal materials are mainly reflected in their material properties. The performance of the sealing material is an important factor to ensure effective sealing. The selection of the sealing material is mainly based on the working environment of the sealing element, such as the use temperature, working pressure, applicable working medium and movement mode. 368 mechanical seal

The basic requirements for sealing materials are as follows:

①Have certain mechanical properties, such as tensile strength, elongation, etc.;

②Appropriate elasticity and hardness, small compression set;

③ High and low temperature resistance, no decomposition and softening at high temperature, and no hardening at low temperature;

④ Compatible with the working medium, without swelling, decomposition, hardening, etc.;

⑤ Good oxidation resistance and aging resistance, durable;

⑥ Wear-resistant, non-corrosive to metals;

⑦Easy to shape and process, low price.　　991.html,
