Viton® is commonly called Fluoro-elastomer/Viton (FPM) and is well known for its excellent (400°F/200°C) heat resistance.

Viton® is perfect for gasket cutting, flat seals, door seals and industrial applications. This is a high tech elastomer designed for extreme heat, oil and chemical resistance. Viton® resists aliphalactic aromatic and halogenated hydrocarbons, concentrated acids, alkalis, animal and vegetable oils.

Viton® offers excellent resistance to aggressive fuels and chemicals and has excellent mechanical properties. This material is also resistant to abrasion and cuts. With a broad spectrum of applications in the automotive, chemical processing and industrial markets, Viton® satisfies many performance specifications. Suitable applications for Viton® include:

  • High temperature gaskets
  • O-rings
  • Lathe cut gaskets and seals

Viton® Restrictions:

Viton® is not generally resistant to ketones, low molecular weight esters (such as ethyl acetate), or nitro containing compounds. Products are not usually serviceable below 15°F.

Viton®B 68% Flourine-Better Chemical Resistance

Acid Resistant Viton®
Viton®B has better resistance and retains flexibility better after dry heat aging than Viton®A. It is recommended for applications requiring maximum retention of elastic properties combined with good mechanical properties. Viton®B is specified by the FSA to resist sulfur dioxide in power generating factory systems.

Chemical Resistance
Viton®B offers superior resistance to both diluted and concentrated aggressive acids. Thermodyn’s exclusive B compound TH-66070-B* made of Viton®B is resistant to various mineral.
