*Related Introduction*

According to the role of the secondary seal of the mechanical seal, the requirements for the material of the secondary seal:

① The material has good elasticity, especially requiring good restorability and small permanent deformation;

② It is not corroded by the fluid medium, and the expansion and contraction in the medium are not large;

③The friction coefficient is small and the wear resistance is good;

④ The use temperature range should be wide (not sticky, hardened and brittle, and lose elasticity at high and low temperatures);

⑤ It must have appropriate mechanical properties, such as tear strength and elongation, pressure resistance, etc., without significant deformation under pressure, and have excellent tear resistance, wear resistance and pressure resistance, etc.;

⑥ It is easy to process and can obtain high precision;

⑦ Good resistance to medium corrosion, dissolution, swelling, aging, etc., and should not pollute the medium.
