Viton fl uoroelastomers are used in critical automotive applications
– FLUOROELASTOMERS – PROVEN PERFORMANCE
How innovative fl uoroelastomers are allowing for uninterrupted supply to customers in the face of an evolving regulatory landscape
F
luoroelastomers are used in a wide variety of high- performance applications for their long-term
reliability and resistance to elevated temperatures and aggressive chemical changes. Chemours’ range of Viton fl uoroelastomers was fi rst introduced in 1957 to meet the high demands of the aerospace industry, and for the next 65 years became known for their outstanding temperature and chemical resistance. In 2001, Chemours developed specialty types of Viton fl uoroelastomers called Viton APA, leading to a step-change in processing and end-use performance. Today, the materials are widely used in the automotive industry and are regarded as a leading sealing technology for emerging markets such as advanced electronics, semiconductors and electric vehicles (EV). Most recently, the company unveiled its newly introduced Viton FWRD APA fl uoroelastomers, which enable customers to maintain uninterrupted supply, despite evolving regulations.

VITON FWRD APA FLUOROELASTOMERS Viton APA fl uoroelastomers dramatically improve processing characteristics, such as fl ow, cure and mould release. Because good physical properties and low compression set can be achieved without post-curing, unique production opportunities, such as over-moulding onto plastic inserts or carriers, are realised. Moreover, engineers and parts manufacturers specify Viton APA fl uoroelastomers for the most demanding applications due to their ability to maintain performance at high and low
temperatures and their exceptional chemical resistance. Responding to shifts in the
industry, Chemours has innovated its manufacturing process to eliminate the use of a fl uorinated surfactant, producing Viton FWRD APA fl uoroelastomers without sacrifi cing performance. With the growing emphasis on
sustainable transportation options, peak performance is required in newer, extreme environments, and Viton fl uoroelastomers continue to deliver peak performance under the most challenging conditions.
