Fluorine rubber sealing material can be made into a variety of uses of gaskets, valve sealing gaskets, ○ sealing ring, V-ring, leather bowl, oil seal and corrugated joint pipe. These products can withstand temperatures above 200 ℃ and do not deform in various oil media. Fluorine rubber sealing materials are mainly used in the automotive and aerospace fields in China, At present, the main products of fluorine rubber material used in domestic automobile parts are engine crankshaft front oil seal, crankshaft back oil seal, valve cylinder oil seal, engine diaphragm, engine cylinder liner water ring, refueling hose, fuel hose, oil filter single valve, refueling cap ○ ring, transmission and reducer oil seal and so on. Fluorine rubber, silicone rubber, acrylic rubber and heat-resistant elastomer have become the development trend and mainstream of automotive rubber materials in the future. Many automotive parts use fluorine rubber with better performance to replace traditional materials.
Fluorine rubber seals used for automotive engine sealing, can work in 200 ℃ ~ 250 ℃ for a long time, the working life can be the same as the engine repair life; Used in chemical industry, can seal inorganic acid (such as 140 ℃ 67% sulfuric acid, 70 ℃ concentrated hydrochloric acid, 90 ℃ 30% nitric acid), organic solvent (such as chlorine hydrocarbon, benzene, high aromatic gasoline) and other organic matter (such as butadiene, styrene, propylene, phenol, 275 ℃ fatty acid, etc.); For deep well oil production, can withstand 149 ℃ and 420 atmospheric pressure harsh working conditions; When used for superheated steam seals, it can work in 160 ~ 170 ℃ steam medium for a long time. In the production of monocrystalline silicon, fluorine rubber seals are commonly used to seal special media at high temperature (300 ℃) - trichlorohydrosilicon, silicon tetrachloride, gallium arsenide, phosphorus trichloride, trichloroethylene and hydrochloric acid at 120 ℃.
