ACM or simply acrylate rubber consists of
a polymerized ester and a curing monomer. Ethyl acrylate rubber
has a good resistance to heat and mineral oil; on the other
hand butyl acrylate has a better cold flexibility. Polyacrylate
has a good resistance to mineral oil, oxygen and ozone even
at high temperatures. The water compatibility and cold flex¬ibility
of ACM are significantly worse than with NBR.
Heat resistance
• Shortened lifetime up to approximately 177°C (350°F).
Cold flexibility
• Down to approximately -21°C (-5°F).
Chemical resistance
• Mineral oil (engine, gear box, ATF oil).
• Ozone, weather and aging resistance.
Not compatible with:
• Glycol based brake fluid.
• Aromatics and chlorinated hydrocarbons.
• Hot water, steam.
• Acids, alkalis, amines.
