Viton® (Vinylidene Fluoride – Hexafluoropropylene) Fluorocarbon
(Viton® is a brand name for fluoroelastomers manufactured by DuPont Dow Elastomers.) This fluoroelastomer provides chemical resistance to a wide range of chemicals, concentrations and temperatures involving mineral acids, salt solutions, chlorinated hydrocarbons and petroleum oils. Although its chemical compatibility to most acids is excellent it can be mechanically swollen by some. In such cases Plast-O-Matic uses a specially cured Viton® to reduce the swell factor encountered with standard Viton®-A.The maximum service temperature of Viton® is 300°F (149°C).
