Beijing specializing in the production of high temperature of 300 degrees perfluorinated O-ring

The physical properties of OTP import fluorine rubber O-ring: Fluorine rubber is a copolymer of vinyl fluoride and hexafluoropropylene, because of its molecular structure and the fluorine content of different fluorine rubber O-ring chemical resistance, resistance high temperature resistance, low temperature are different. Fluorine rubber English name FKM, DuPont produced fluorine rubber material called viton named VT. Wall top companies in the fluorine rubber compound choice is Japanese gold DuPont, a good choice because the rubber, so Wal-top O-ring quality has been very stable, and has been recognized by customers. Overall performance fluorine rubber is very good, whether in oil, high temperature, wear resistance, corrosion resistance has well represented. Fluorine rubber O-ring common color is brown, black. There are green, other colors can also be made. Black VITON75 Viton O-ring temperature range: static sealing: low temperature -26 ℃, 275 ℃ high temperature dynamic seal: low temperature -15 ℃, temperature 200 ℃ temperature VITON fluorocarbon material disadvantages -O-ring (for in a variety of demanding industrial applications) elastomers: Viton or peroxide-cured bisphenol fluorine rubber O-ring has a strong high temperature and low temperature (-40-240oC) performance has good oil characteristics very good resistance dielectric properties, especially freon, acids, bases having all good resistance to corrosion carbohydrates (oil, grease, solvent) fluorine rubber has a low gas permeability in the high-pressure chemical resistant properties has a very strong anti- compression permanent deformation, tear resistance, abrasion resistance temperature VITON O-ring imported application: commonly used in automotive, aircraft engine seals, long-term use at 250 ℃, very suitable for the engine power output shaft seal, can also be used for engine valve stem seals, cylinder liner seals, clutch seals, seal air filter, fuel pump and fuel instructors inner plastic seals, etc., fluorine rubber seals can only be used under high vacuum conditions.
