??What are the requirements for mechanical seal performance

??Performance of the sealing material is an important factor to ensure effective sealing, choose the sealing material, the sealing member is mainly based on the work environment, such as temperature, pressure of work, the working medium and the use of movement and so on. The basic requirements for the sealing material is as follows:

??1. With certain mechanical properties such as tensile strength, elongation and the like;

??2. appropriate elasticity and hardness, compression set is small;

??3. The high and low temperatures, does not decompose at high temperatures, softening, hardening at low temperatures;

??4. working medium and adapt, no swelling, decomposition, hardening;

??5. oxygen resistance and good resistance to aging, durable;

??6. wear-resistant, non-corrosive metal;

??7. Ease of forming, low prices.
