FPM-Viton® O-Rings, elasticity and resistance
FPM-Viton® O-Rings are sealing rings for high temperature applications and/or in contact with agressive chemical products. Among the whole synthetic rubbers, FPM-Viton® is the most resistant to halifatic, aromatic and chlorinated hydrocarbons.
Viton® is a Chemours’ trademark and is a thermopolymer of hexafluorpropilene, with fluoride of vynilidene, tetrafluoroethylene and etherperfluor methyl Vynil. Its international abbrevation is FPM or FKM (Fluorocarbone monomer).

|FPM||50 – 90||-20 to +200/+220|
Properties and advantagesFPM-Viton® O-Rings offer great resistance to:
- Ozone, weather and UV rays
- Acids, alcalyse, oils et greases
- This kind of seals offers very good compression set values at high temperature
- In addition, they do not spread flame so that they are auto-extinguishable
- Esthers and ketones
Viton® is a fluoroelastomer obtained from the derivation of synthetic rubber and fluoropolymer elastomer. O-Rings made of this material provide enhanced resilience and increased resistance to aggressive fluids.
