Fluoroelastomers (Viton)
Fluoroelastomers refer to a family of synthetic rubber compounds specifically designed to have superior resistance to oils, gasses, and chemicals at higher temperatures. Often sold under the Chemours’ trademarked name of Viton, these materials are used to mold parts or as roller covers for use in specific high heat environments. Fluoroelastomers have excellent resistance to certain oils and hydrocarbons but very poor performance when exposed to ketones and alcohol. Like HNBR, fluoroelastomers are expensive but often the only material to handle certain demanding conditions.
