Polyacrylate (ACM) is a class of copolymer of ethyl and acrylates. It is suitable for use in automotive automatic transmissions, steering systems, and other applications where petroleum and high temperature resistance are required. Polyacrylate also exhibits resistance to cracking when exposed to ozone and sunlight. It is however not recommended for applications where the elastomer will be exposed to brake fluids, chlorinated hydrocarbons, alcohol, or glycols. It also exhibits fair to low water resistance.

Polyacrylate is suitable for dynamic and static seal of o-rings in the environment containing the following chemicals: Air below 200 C, Aluminium Chloride, Ammonium Chloride, Animal Oil, ASTM Fuel A, ASTM Oil One, ASTM Oil Three, ASTM Oil Two, Automatic Transmission Fluid, Benzine (Ligroin), Bunker Oil, Butane, Butter, Calcium Chloride, Calcium Nitrate, Carbonic Acid, Castor Oil, Tung Oil China Wood Oil, Cod Liver Oil, Corn Oil, Coal Tar Creosote, Crude Oil (Asphalt Base), Dow Corning 550, Elco 28 Lubricant, Ethane, Freon 113, FREON R134A, Fuel Oil, Petroleum Base Grease, Helium, Heptane, Hexane, Iso Octane, Animal Fat Lard, Linsed Oil, Petroleum Base Lubricating Oils, MIL-F-25558 (RJ-1), MIL-R-25576 (RP-1), Type 1 Fuel MIL-S-3136, MIL-S-81087, Mineral Oils, Neatsfoot Oil, Gas Nitrogen, N-Pentane, Peanut Oil, Pine Oil, Potassium Nitrate, Potassium Sulfate, Transformer Oil Pyranol, RJ-1 (MIL-F-25558), RP-1 (MIL-R-25576), Silicone Grease, Silicone Oils, Silver Nitrate, Sodium Chloride, Soyabean Oil, Stoddard Solvent, Type A Transmission Fluid.

O-Ring material Polyacrylate is usually suitable for static seal in the environment containing Ammonium Nitrate, Argon, ASTM Oil Four, Borax Solutions, Cyclohexane, Diesel Oil, Di-ester Lubricant MIL-L-7808, Ethyl Acetoacetate, Ethylene, Freon 22, Hydrogen Gas, JP 3 MIL-J5624, JP 6 MIL-J5624, Methane, Methanol, MIL-F-25656, MIL-G-25760, MIL-H-5606, JP-5 JP-4 JP-3 MIL-J 5624, MIL-L-25681, Naphtha, Natural Gas, Oleic Acid, Cold Oxygen, Ozone, Petroleum Oil, Producer Gas, Rapeseed Oil, Red Oil, Turbine Oil, Turpentine.

O-Ring material Polyacrylate is sometimes ok for static seal but not for dynamic seal in the environment containing chemicals such as Dow Guard, Ethyl Chloride, Isopropyl Ether, Methyl Bromide, Phosphoric Acid, Radiation.
