The physical properties of import DuPont fluorine fluorine rubber O-ring imported rubber O-rings: Viton is a copolymer of vinyl fluoride and hexafluoropropylene, because of its molecular structure and fluorine content of different fluorine rubber O-ring chemical resistance, heat resistance, low temperature 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. The main feature is the high temperature Viton and chemical resistant, and have a good anti-aging and anti-ozone performance, and very low permeability tolerance. Even under very poor working conditions, there is still a very good wear resistance. Fluorine rubber can withstand +200 degrees or below operating temperature, but also allows you to run a short time without oil case. Viton is resistant to oil, hydraulic oil, fuel, lubricants, inorganic acids, aliphatic hydrocarbons and aromatic hydrocarbons, etc., but in case there are esters, ethers, ketones, certain amines and hot water, hydrogen fluoride compound, You should not use fluorine rubber. In normal working conditions and operating temperature below +200 degrees, fluorine rubber is very stable and harmless. But the face of more than 300-degree heat, such as gas cutting gun fire, fluoro rubber will release harmful gases. Inhalation of these gases into the eyes or cause damage to human health. Viton seals Once heated to temperatures above 300 degrees, even after cooling process will be in danger, and therefore must not be any direct contact with the skin
