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 and an intermittent limit of . ACM is polar and lacks unsaturation. It is resistant to ozone and has low permeability to gases. Its disadvantage is its low resistance to moisture, acids, and basess. It should not be used in temperatures below .

It is commonly used in automotive transmissionss and hoses. It is also used in shaft seals, adhesives, beltings, gaskets and O-rings. It is used in vibration damping mounts due to the damping properties.
