Description: Viton was introduced in 1957 as a high-performance aerospace sealing elastomer. It is now also used in other industries including automotive, fluid power, appliance, and chemical industries. It is noted for its outstanding performance in very hot and extremely corrosive environments. Compounds of Viton remain elastic indefinitely at 204°C or when exposed intermittently to 260°C under laboratory conditions. Viton is generally serviceable down to -18 to -23°C, although special formulations permit static use down to -54°C (-65°F). Also, Viton has proven to be satisfactory for static seals under conditions approaching absolute zero. Viton has excellent resistance to oils, fuels, lubricants, and most mineral acids. It has extremely low permeability to a broad range of substances. It is resistant to aliphatic, aromatic hydrocarbons. It is extremely resistant to compression set, even at high temperatures. It has exceptional good resistance to atmospheric oxidation, sun, weather, fungus, and mold. It has good electrical properties in low voltage, low frequency applications and low burning characteristics.
