Fluoro Elastomer rubber or Viton is based on hexafluoropropylene vinylidene fluoride. The polymer has high resistance to heat with a temperature range of -40° C to + 250° C. It has also possesses a good flame resistance and are usually self extinguishing. FKM’s have excellent resistance to oxygen, ozone and natural weathering and also have outstanding resistance to compression, especially at elevated temperatures. Its resistance to most solvents and chemicals give long service life as it has excellent resistance against huydrocarbons, aliphatics, aromatic and chlorinated chemicals and resistance to acids and alkalis including oxidants. However, they have poor performance against ethers, ketones and bases.
