Viton® Fluoroelastomer Fluorocarbon

Viton® (Fluoroelastomer / Fluorocarbon)

Fluoroelastomers or Fluorocarbons, widely known as Viton®, are among the most suitable rubbers for continuous use at temperatures of 200°C, and up to 300°C for short periods. Various grades are available depending upon whether compression set, flexibility (as in diaphragms) or chemical resistance is the prime concern. Fluoroelastomers have excellent resistance to ozone and weathering, oils and most chemicals. They are, however, very expensive, and unsuitable for use with phosphate esters and ketones and have poor low-temperature capabilities.

Viton® is a registered trade mark of DuPont Performance Elastomers

Die-Cut Products stocks a broad spectrum of sponges & rubbers for your custom fabrication needs. This includes both solid rubbers as well as open-cell and closed-cell sponge rubbers. All materials are available with full cure date, shelf life, and supplier test reports right from the mill. Need RoHS-compliant material? We offer that too!

Benefits of Viton Rubber & Sponge

Fluorocarbons are highly resistant to swelling when exposed to gasoline, as well as resistant to degradation due to exposure to UV light and ozone. When exposed to low temperatures, fluorocarbon elastomers can become quite hard (-4 °F) but can be serviceable at low temperatures, although FKM compounds are not recommended for applications requiring good low-temperature flexibility.

Fluorocarbons exhibit low gas permeability, making them well-suited for hard vacuum service, and many formulations are self-extinguishing. FKM materials are not generally recommended for exposure to hot water, steam, polar solvents, low molecular weight esters and ethers, glycol-based brake fluids, or hot hydrofluoric or chlorosulfonic acids. Viton has good compression set resistance.

Typical temperature range for Viton is +5°F to +390 °F
