Viton (FKM, FPM, VITON)

  • Fluorocarbon(FPM,FKM,VITON)
  • Fluorocarbon is a well-known high performance rubber,and especially it has excellent resistance to high temperature,ozone,weather,oxygen,mineral oil,fuels,hydraulic fluids,aromatics and many organic solvwents and chemicals.Now we can supply parts made by.
  • Fluorine Content
  • Viton system gum like general type(A-TYPE,66% fluorine),middle fluorine content type(B-,GBL-TYPE,67-68.5% fluorine),high fluorine content type(F-,GF-TYPE,70% fluorine),improving low temperature flexibility type(GLT-GFLT)and excellent resistance to more chemicals and solvents-Viton ETP Extreme.We also can supply excellent acid and alkali resistance parts made by VITON TBR.
  • Cure system-Bisphenol-Cured vs.Peroxide-Cured
  • ●Standard FKM compounds are Bisphenol cured.FKM compounds with peroxide-cured possess better acid solution resistance than the bisphenol cured,and can replace litharge-cured applied in acid solution.In Some lubricants adding a few organic amide or amine,choosing peroxide curing system Viton will be better than bisphenol curing system
  • Other Common Variations
  • ●FKM can also be submitted for approval to Underwriters Laboratories(UL)for use in applications as prescribed in UL157.
  • ●FKM has excellent resistance to high temperature,oil,solvent,flame,chemical and weather,and it is usually applied in automotive,chemical processing,aerospace and many industrials
  • ●Viton GLT is broadly used in thermal range of -40℃to +250℃ and it has outstanding resistance to aggressive HTS-type oils which are comminly used in aerospace industry.
  • ●Viton ETP is usually applied in chemical industrial
  • ●In some fuels adding several methanol,viton F and B-type are more usable than A-type especially F-type.If it requires lower temperature,GFLT and GBLT will be available
  • ●Viton TBR 605C (TFE/propylene polymer)is better base and steam resistant than other general vitons.It can be use in amine,amide and some bases.
