Acrylic rubber

Acrylic rubber, known by the chemical name alkyl acrylate copolymer (ACM) or the tradename HyTemp, is a type of rubber that has outstanding resistance to hot oil and oxidation. It belongs to specialty rubbers. It has a continuous working temperature of 150 °C (302 °F) and an intermittent limit of 180 °C (356 °F). ACM is polar and lacks unsaturation. It is resistant to ozone and has low permeability to gases.^[1] Its disadvantage is its low resistance to moisture, acids, and bases. It should not be used in temperatures below −10 °C (14 °F).

It is commonly used in automotive transmissions and hoses.^[2] It is also used in shaft seals, adhesives, beltings, gaskets and O-rings.^[3][4] It is used in vibration damping mounts due to the damping properties.^[1]
