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 temperature, the working pressure, the working medium used, and the movement mode. 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 permanent deformation;

3. High temperature 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 oxygen resistance and aging resistance, durable;

6. Wear-resistant and non-corrosive to metals;

7. Easy to shape and process, low price;
