Performance requirements of sealing materials2021-01-04 The performance of sealing materials is an important factor to ensure effective sealing. The selection of sealing materials is mainly based on the working environment of the sealing element, such as temperature, working pressure, working medium used and movement mode Wait. The basic requirements for sealing materials are as follows: 1. Have certain mechanical properties, such as tensile strength, elongation, etc.; 2. Appropriate elasticity and hardness, small compression set; 3. High temperature and low temperature resistance, no decomposition under high temperature, Softening, not hardening at low temperature; 4. Compatible with the working medium, no swelling, decomposition, hardening, etc.; 5. Good oxygen resistance and aging resistance, durable; 6. Wear resistance, no corrosion of metals; 7. Easy to form and process, low price;
