Viton* fluoroelastomer

Performance of Viton™ fluoroelastomer

Viton™ consists of several standard and specialty types of polymers based on their composition and fluorine content.

The types differ primarily in the end-use performance of parts made from Viton™. Each differs in its ability to resist permeation and volume increase, and resist attack and property degradation caused by the chemicals and fluids.

The latest types of Viton™ made with Advanced Polymer Architecture (APA) are indicated by an "S."

The choice of the most appropriate Viton™ product to use for any given end-use application will be determined by the end-use service, and in particular, whether the finished part must provide:

  • Resistance to amines or caustics
  • Resistance to hydrocarbon fluids
  • Flexibility at low temperature (ability to maintain a seal at low temperature)

The end-use performance capabilities of the various types of Viton™ differ primarily in terms of these three factors.
