Viton
VITON®
Denver Rubber Company holds an extensive inventory of Viton Rubber, known as fluoroelastomer rubber, a brand of synthetic rubber and fluoropolymer elastomer commonly used in O-rings and other molded or extruded goods. The name is a registered trademark of DuPont Performance Elastomers L.L.C. Categorized under the ASTM D1418 and ISO 1629 designation of FKM. This class of elastomers is a family comprising copolymers of hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), terpolymers of tetrafluoroethylene (TFE), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialties. The fluorine content of the most common Viton grades varies between 66% and 70%.

TYPES OF VITON RUBBER
COMMERCIAL VITON
Made with a smooth or Nylon Fabric finish, this material offers a range of resistances from oils, fuels, lubricants, mineral acids, oxidation, and weather to fungus and mold. This Viton material has great resistance to many aliphatic hydrocarbon fluids acting as solvents and exceptional compression set attributes at temperatures from -20°F to +400°F that embrittle other non-fluorinated elastomers.
