Jing'an District fluorine rubber o-ring Business Which is better? Shanghai gifted professional production of fluorine rubber sealing O-ring | fluorine rubber seal | oil seal | TC oil seal | silicone waterproof seal, and so on. It refers to a carbon atom of the main chain or side chain of a polymer containing a synthetic elastomer fluorine atoms, such rubber with special rubber incomparable advantages in general, it has many excellent performance, widely used in petrochemical, chemical, automobiles, machinery, light industry, requires a demanding critical parts. 1, high temperature performance: long-term use at 250 ℃, short-term use at 300 ℃, the anti-aging, excellent weathering performance. 2, chemical resistance: the stability of organic liquids, acids, alkalis, oil and other chemicals are superior to other rubber. 3, resistant to hot water, and steam performance: excellent recipe fluorine rubber, for hot water, high temperature steam has excellent stability. 4, flame resistance, high vacuum performance: it comes in contact with fire can burn, but after leaving the flame self-extinguishing, are self-extinguishing rubber, it has excellent resistance to vacuum. Viton O-ring is a circular cross-section of the rubber ring. It is mainly used for static seals and reciprocating seals. The use of speed range is generally 0.005 ~ 0.3m / s. Seal for rotary motion, the only low-speed rotary sealing device. Hydraulic excavators central rotary joint distribution valve seals institutions. General O-rings are used infrequently in rotary motion sealing device. O-rings are generally mounted on the outer or inner circle cross-section from the seal rectangular groove.
