Acrylic rubber is a type of synthetic rubber containing acrylonitrile. The chemical name of this rubber is Alkyl acrylate copolymer. The outstanding property of this rubber is its resistance to hot oil and to oxidation. These Rubber is suitable for continuous use at temperatures up to 150 degree celsius and at intermittent exposure up to about 180 degree celcius. It has however poor resistance to water or moisture. ACM rubber is usually not suitable for use much below -10 degree celsius and also has poor resistance to acids and bases. Acrylic rubber is widely used in automotive transmissions and hoses.
