Fluoroelastomers (FKM/FFKM)

Advantages of fluoroelastomer(FKM)

What's the fluoroelastomer(FKM)?

Fluoroelastomer is one of the newest and most promising members of the elastomer family.
Fluoroelastomer  resist a wide variety of corrosive fluids at elevated temperatures while retaining their mechanical properties.Other important features of Fluoroelastomer include resistance to weathering ozone,oxygen and flame...good tensile strength,resilience,low compression set.Because it has above excellent propertiews,fluoroelastomer is widely used in automobile,aerospace,aircraft,chemical processing,petrochemical and power supply industries.

  • Heat Resistance over 250℃ even up to 275℃
  • Solvent resistance,the widest applicable field
  • Acid resistance & low permeability
  • Flame Retardant & self extinguished
  • Oil resistance, the best among the elastomers
