Viton Extreme

Viton Extreme offers more universal chemical resistance than either standard grades of Viton. or TFE/P Elastomers. In addition, Viton Extreme tm offers similar base resistance to VTR 7430.

Viton Extreme was originally developed to resist Sour (H2S) petroleum environments that are commonly found in the oil field. However, it has become widely used in the Chemical Processing, Petroleum Refining, Semiconductor and Chemical Transportation industry.

Today's blended fuels with additives and oxygenates such as MTBE, TAME, ETBE and alcohols offer difficult sealing solutions that Viton Extreme can solve without the cost of high performance perfluoroelastomers (Kalrez).
