The basic requirements for sealing materials are as follows:

• Have certain mechanical properties, such as tensile strength, elongation, etc.;
• Appropriate elasticity and hardness, small compression set;
• High temperature and low temperature resistance, no decomposition or softening at high temperature, and no hardening at low temperature;
• It is compatible with the working medium, without swelling, decomposition, hardening, etc.;
