Polyacrylate (ACM)
ACM (acrylic rubber) has good resistance to mineral oil, oxygen and ozone. Water compatibility and cold flexibility of ACM are significantly worse than with nitrile.
Heat resistance
• 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
Not compatible with:
• Glycol based brake fluid (Dot 3 and 4)
• Aromatics and chlorinated hydrocarbons
• Hot water, steam
• Acids, alkalis, amines
