EPM is a copolymer of ethylene and propylene.
Ethylene¬propylene-diene rubber is produced using a third
monomer and is particularly useful when sealing phos¬phate-ester
hydraulic fluids and in brake systems that use fluids having
a glycol base.
Heat resistance
• Up to 150°C (302°F) (max. 204°C (400°F))
in water and/ or steam).
Cold flexibility
• Down to approximately -57°C (-70°F).
Chemical resistance
• Hot water and steam up to 149°C (300°F) with
special compounds up to 204°C (400°F).
• Glycol based brake fluids up to 149°C (300°F).
• 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).
