Viton® consists of essentially several standard and specialty types of polymers based on their composition and flourine content. The types differ primarily in the end-use performance of parts made from Viton®. Each type differs in its ability to: resist permeation and volume increase, 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 type of Viton® 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 capability of the various types of Viton® differ primarily in terms of these three factors.
