1. the main features Fluorine rubber is mainly used in cars and motor vehicle industry, because of its high temperature resistant, oil resistant and medium resistance is excellent, it’s mainly produce the oil seal and O ring. 2. performance Fluorine rubber with high chemical stability, which is one of the best elastomer medium resistance of all kinds.26 type fluorine rubber oil resistant base oil, double ester oils ethers, silicon oil, oil, silicate inorganic acid resistance, resistance to most organic and inorganic solvents, drugs, etc, is not only resistant to low molecular, ether, ester, ketone amine and ammonia, hydrofluoric acid, chlorosulfonic acid, phosphoric acid type of hydraulic oil.23 type fluorine rubber dielectric properties similar to 26 type, and even more unique, its strong oxidation resistance of the inorganic acid such as fuming nitric acid, sulfuric acid performance is better than 26 type, 98% HNO3 at room temperature the macerate in 27 days its volume expansion is only 13% ~ 15%. 3. the main usage Fluorine rubber seals for the engine sealing, can work under 200 degree centigrade ~ 250 degree centigrade in the long-term, short-term work under 300 and, its working life can be the same as the life of the engine repair, a total of 1000 ~ 5000 flight hours (5 ~ 10 years);When used in the chemical industry, can seal inorganic acid (such as 67% of sulfuric acid under 140 degree centigrade, 140 degree centigrade concentrated hydrochloric acid, and degree centigrade the nitric acid of 30%), organic solvents, such as high aromatic hydrocarbons, chlorinated hydrocarbons, benzene, gasoline) and other organic matter (such as propylene, butadiene, styrene, phenol, under the 275 degree centigrade of fatty acids, etc.);When used in deep well drilling, can work under 149 degree centigrade and 420 atmospheres of harsh conditions;When used in superheated steam seal, but in 160 ~ 170 degree centigrade steam medium to medium to work.Commonly used in the production of monocrystalline silicon, fluorine rubber seals to seal of high temperature (300 degree centigrade) under the special medium - chemical hydrogen silicon, silicon tetrachloride, gallium arsenide, phosphorus trichloride, trichloroethylene and 120 degree centigrade of hydrochloric acid, etc.
