Fluorine rubber seal ring is a kind of sealing ring made of vinyl fluoride and hexafluoropropylene copolymer. It has excellent flame retardant, air tightness, high temperature resistance, ozone resistance, weather resistance, oxidation resistance, mineral oil resistance, fuel oil resistance, aromatic resistance and many organic solvents and chemicals performance. These characteristics make the fluorine rubber seal ring has high stability and durability in high temperature environment.
According to the relevant information on the market, the use temperature range of fluorine rubber sealing ring under static seal is about -26 ° C to 282 ° C, although it can be used in a short time when the temperature is as high as 295 ° C, but when the temperature exceeds 282 ° C, its service life will be shortened. Under the dynamic seal, the temperature range of the fluorine rubber seal ring is -15 ° C to 280 ° C, and the low temperature can reach -40 ° C. In general, the high temperature resistance of fluorine rubber seals is very good.
It is worth mentioning that the fluorine rubber sealing ring also has a good performance in chemical corrosion resistance. In general, in terms of chemical acid and alkali corrosion resistance, fluorine rubber or EPDM O-type sealing rings are commonly used. In contrast, fluorine rubber has a wider range of applications in terms of chemical resistance and higher temperature resistance, up to 240 ° C, while EPDM rubber O-rings can only reach 150 ° C.
Fluorine rubber sealing rings have been widely used in many fields. In the chemical process and petroleum refining industry, fluorine rubber sealing rings are used in mechanical seals, pumps, reactors, agitators, compressor housings, valves, all kinds of instruments and other equipment. Fluorine rubber seals also play an important role in analytical and process instruments, such as diaphragms, diaphragms, column fittings, hoops, gaskets, etc. Semiconductor manufacturing, food, aviation and aerospace and other fields are also inseparable from the excellent performance of fluorine rubber seals.
Fluorine rubber sealing ring has been widely used in many fields because of its excellent high temperature resistance and chemical corrosion resistance. In the future development, fluorine rubber seals will continue to provide more stable sealing solutions for various industries.
