FPM (named DIN/ISO) or FKM (ASTM) is a material characterized by a good resistance to the high thermal and chemical products, but has limited resistance to cold.

 Thermal operating range: -20°C to +200°C (with peaks at 250°C)

Hardness: 60 to 90 Shore A

Good resistance to:

• • oils and greases
  • gas
  • ozone and U-V
  • hydrocarbons
  • alphatic and aromatic solvents
  • acids

Low resistance to:

• • alkalis
  • brake fluids
