What is Viton® Rubber?
Viton® rubber is a high-performance fluoroelastomer polymer (FKM) that was first introduced to the aerospace industry in 1957. Its use quickly spread to other sectors, including automotive, chemical, fluid power, and appliances.<
Due to its high fluorine content, Viton® offers exceptional performance in extremely hot and corrosive environments. It provides superior resistance to aging, oxidizers, ozone, oils, and various chemicals. However, Viton® has limited applicability in low-temperature environments.
There are also multiple grades available for Viton® rubber, including copolymers and terpolymers. Common grades of Viton® include hexafluoropropylene, tetrafluoroethylene and vinylidene fluoride. Additonally, Viton® was also the first elastomer of its kind to earn ISO 9000 registration worldwide.
Viton® is a registered trademark of DuPont Performance Elastomers.
