The performance of the sealing material is an important factor to ensure an effective seal, the choice of sealing materials, the sealing elements of the work environment, such as temperature, pressure of work, the use of media and sport. The basic requirements of the sealing material is as follows:
With certain mechanical properties such as tensile strength, elongation, etc.;
Elasticity and hardness appropriate, compression permanent deformation is small;
(3) high temperature and low temperature, high temperature does not decompose, softening, hardening at low temperatures;
Compatible with the working medium, does not produce swelling, decomposition of sclerosis;
Resistance to oxygen and resistance to aging, durable;
Wear-resistant, non-corrosive metal;
Ease of forming, low prices;
