VITON Rubber Material Characterization

Viton, also known as Fluorinated Hydrocarbon Rubber, is a high-performance synthetic rubber and a type of fluororubber. It is a copolymer of hexafluoropropylene (HFP) and vinylidene fluoride (VDF). Synthetic rubber is an artificially synthesized high-elasticity polymer, primarily derived from coal, petroleum, and natural gas.

There are many varieties of synthetic rubber, and it can be synthesized to meet various specific performance requirements. Consequently, the global production of synthetic rubber has far exceeded that of natural rubber. Viton was developed by DuPont and is now owned by Chemours Company. It is distinguished by its excellent resistance to high temperatures, chemicals, and oils, making it an indispensable material under extreme conditions.

Viton fluororubber exhibits high chemical stability, making it one of the best media-resistant elastomers available today. Its high-temperature resistance is comparable to that of silicone rubber, arguably the best among elastomers. Viton can operate at temperatures ranging from 200°C to 250°C for extended periods, and it can even withstand higher temperatures for short durations.

This type of fluororubber has exceptional resistance to various types of oils and chemicals, including gasoline, diesel, and other petroleum products. It also demonstrates good stability under conditions of UV light, oxygen, and ozone, making it less prone to aging.

Viton fluoroelastomers are 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.
