What is Viton®? General Properties, Compatibility & More
Viton® is a specific brand of synthetic rubber and fluoropolymer elastomer that is commonly used to manufacture chemical resistant o-rings, seals, and gaskets. The material is categorized as an FKM material under ASTM D1418 and ISO 1629 standards. Viton® is known for its high density—over 1,800 kg/m3—which is significantly higher than most other types of rubber, which generally top out at approximately 1,520 kg/m3.
Viton® sealing products are resistant to high temperatures, petroleum products, solvents, and a wide range of chemicals. In general, this material is compatible with hydrocarbons, but incompatible with acetones, ketones, steam, hot water, and organic acids.
Viton® Fluorocarbon Options
The Viton® family of fluorocarbon materials is comprised of copolymers of HFP (hexafluoropropylene) and VDF or VF2 (vinylidene fluoride); terpolymers of TFE (tetrafluoroethylene), VDF (vinylidene fluoride), and HFP (hexafluoropropylene); and PMVE (perfluoromethylvinylether) containing specialty additives. Most grades of Viton® include 66-70% fluorine content.
A (Dipolymers of VF2/HFP)
Type A Viton® polymers are used for general purpose o-rings, gaskets, and seals, including automotive and aerospace applications. These materials feature 66% fluorine content.
B (Terpolymers of VF2/HFP/TFE)
Type B Viton® polymers are formulated for use in chemical processing plants, power/utility applications, and the like. These materials include 68% fluorine content.
F (Terpolymers of VF2/HFP/TFE)
Type F Viton® o-rings, seals, and gaskets are highly resistant to oxygenated automotive fuels, concentrated aqueous inorganic acids, water, and steam. Fluorine content of these materials is roughly 70%.
Specialty Viton® Materials
Specialized types of Viton® include GLT, GBLT, GFLT, and Viton® extreme (copolymers of TFE/propylene and ethylene/TFE/PMVE). These materials are ideal for automotive applications, oil exploration, special sealing requirements, and ultra-harsh environments.
