product description

Advantages of silicone products with silicone O-rings:
1. The sealing ring has outstanding sealing function within the operating pressure and a certain temperature range, and can actively improve sealing function with the addition of pressure.
2. The friction between the sealing ring equipment and the moving parts should be small, and the friction coefficient should be stable.
3. The sealing ring has strong corrosion resistance, is not prone to aging, has a long service life, good wear resistance, and can actively compensate for wear to a certain extent.
4. The structure of the sealing ring is simple, and it is convenient to use and protect fluorine rubber. The fluorine rubber sealing ring has good corrosion resistance, which makes the sealing ring have a longer lifespan.
Knowledge of silicone products:
Silicone rubber refers to rubber whose main chain is composed of alternating silicon and oxygen atoms, with two organic groups usually connected to the silicon atoms. Ordinary silicone rubber is mainly composed of siloxane chains containing methyl groups and a small amount of vinyl groups. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve the temperature and oil resistance of silicone rubber.
Because silicone has the advantages of high temperature resistance, oil resistance, high vacuum resistance, acid and alkali resistance, and resistance to various chemicals, it has been widely used in modern aviation, missiles, sailing, rockets, world flight, ships, atomic energy and other top-level technologies, as well as in industries such as sedans, shipbuilding, chemical machinery, petroleum machinery, telecommunications, instruments, etc.
