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 fluorine content of different fluorine rubber O-ring chemical resistance high temperature resistance, low temperature type are different. Fluorine rubber English name FKM, DuPont produced fluorine rubber material named viton referred VT. Wall top companies in the fluorine rubber compound choice is Japanese gold DuPont, because compound selected good, 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 has well represented. Fluorine rubber O-ring common color is brown, black. There are green, you can make other colors. Black VITON75 Viton O-ring Temperature range: static sealing: low temperature -26 ℃, 275 ℃ high temperature dynamic seal: low temperature -15 ℃, high temperature 200 ℃ high temperature VITON fluorocarbon material advantages and disadvantages of -O-ring (for in a variety of demanding industrial applications) elastomers: Viton bisphenol or a peroxide vulcanizing fluorine rubber O-ring has strong high temperature and low temperature (-40-240oC) performance good oil characteristics very good resistance to media performance, especially for Freon, acids, alkalis all good resistance to corrosion carbohydrates (oil, grease, solvents) fluoro rubber has low gas permeability in a high pressure resistance performance chemicals has a very strong anti- compression permanent deformation, tear strength, abrasion resistance O-ring imported high temperature VITON Applications: Commonly used in cars, aircraft engine seal, 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 seals and fuel instructors inner plastic, etc., fluorine rubber seals can only be used under high vacuum conditions.
