EPDM (Ethylene Propylene, EPM) Not FDA

EPDM is a copolymer of ethylene and propylene. Ethylene propylene diene monomer (EPDM) is produced using a third monomer and is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base. Heat resistance-Up to 300°F (149°C) (max. 400°F (204°C) in water and/or steam).
Cold flexibility-Down to approximately –70°F (–57°C).

Chemical resistance:

  • Hot water and steam up to 300°F (149°C) with special compounds up to 400°F (204°C)
  • Glycol based brake fluids up to 300°F (149°C)
  • Many organic and inorganic acids
  • Cleaning agents, soda and potassium alkalis
  • Phosphate-ester based hydraulic fluids (HFD-R)
  • Silicone oil and grease
  • Many polar solvents (alcohols, ketones, esters)
  • Ozone, aging and weather resistant.

Not compatible with:Mineral oil products (oils, greases and fuels).
