(1) Elasticity and reincarnation;

(2) Appropriate mechanical strength, including expansion strength, elongation, and tear resistance.

(3) Stable performance, not easily bloating in the medium, and small shrinkage effect (scorched ear effects).

(4) Easy processing and forming and maintaining precision size.

(5) Do not corrode contact surface, non -pollution medium, etc.

1. Within the work pressure and a certain temperature range, the sealing ring should have good sealing performance, and it can automatically improve the sealing performance with the increase of pressure.

2. The friction between the sealing ring device and the motion parts should be small, and the friction coefficient should be stable.

3. The sealing ring has strong corrosion resistance, is not easy to aging, has long working life, good abrasion resistance, and can automatically compensate to a certain extent after wear.

4. The structure is simple, the use and maintenance of the sealing ring, and the advantages of the fluorine rubber sealing ring to make the sealing ring have a longer life.
