ETHYLENE ACRYLIC RUBBER
|Ethylene Acrylic, or AEM, rubber is generally used in applications requiring a tough rubber that combines good oil resistance, with heat resistance greater than nitrile or chloroprene, at a cost well below that of silicone or fluorocarbon rubbers. Good low temperature properties are imparted by the ethylene content, while the acrylate provides a considerable degree of oil resistance. Ethylene Acrylic rubber is highly saturated, and as a result exhibits excellent resistance to ozone and weathering. Ethylene Acrylic compounds are well suited for applications requiring continuous exposure to hot (300°F) aliphatic hydrocarbons, including most common automotive lubricants and hydraulic fluids. Water and ethylene glycol resistance is good, but softening can occur after long term exposure above 200°F. AEM's good dampening characteristics make it well suited for vibration mounts, pads, and isolators.|
|Medium density copolymer of ethylene and methyl acrylate. May also contain a small amount of a third monomer containing carboxylic acid to provide active cure sites in the polymer chain.|
