Fluoroelastomer Rubber
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, unsuitable for use with phosphate esters and ketones and have poor low temperature capabilities.
Typical applications include accumulator bladders, diaphragms, gaskets, O-rings and seals operating in especially harsh environments.
Viton® is a registered trade mark of DuPont Performance Elastomers.
