Description:
Even in the harshest environments, subjected to temperature extremes and harsh chemicals, Viton fluoroelastomers perform extremely well. With that in mind, this rugged rubber is ideally suited for applications requiring hard-wearing Bush. Viton might just be the most durable and high-performance rubber material that you’ve never heard of. Here, 360 Industrial Products Co. gives the full lowdown on this impressively versatile fluoroelastomer.
Viton® is a synthetic rubber and fluoropolymer elastomer, commonly used in Bush and other molded or extruded products. This family of elastomers comprises copolymers of terpolymers of tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialty polymers. Viton has become the most commonly associated name with this fluoropolymer family. There are four families of Viton polymers, and the fluorine content of these most popular Viton grades varies between 66 and 70%. The main grades are A (Dipolymers of VF2/HFP), which has a fluorine content of 66%; B (Terpolymers of VF2/HFP/TFE), which commonly used for seals or bush and contains 68% fluorine; F (Terpolymers of VF2/HFP/TFE), which is used in oxygenated automotive fuels and has 70% fluorine content; and finally specialty types (such as GLT, GBLT, GFLT & Viton Extreme), which are used in automotive and oil exploration applications.
The advantage:
Compared to most other elastomers, Viton is better able to withstand high temperature, while simultaneously retaining its good mechanical properties. Oil and chemical resistance are also essentially unaffected by elevated temperatures. Compounds of Viton remain substantially elastic when exposed to laboratory air oven aging up to 204°C or to intermittent exposures up to 316°C. Viton grades also resist degradation from a wider variety of chemicals and fluids – including oils, fuels, lubricants, and most mineral acids – than any other non-fluorinated elastomer. In layman’s terms, that means it provides the best fluid resistance of any commercial rubber. With its low permeability to such a broad range of substances, Viton is known to deliver exceptionally good performance in oxygenated automotive fuels. The rugged characteristics Viton don’t stop there, however. Because they also display good resistance to compression, even at temperatures that would make other non-fluorinated elastomers brittle. It is also especially resistant to atmospheric oxidation, sun, climatic conditions, fungus, and mold. Furthermore, Viton has good electrical properties (in low voltage, low-frequency applications) and low burning characteristics.
