Acrylate rubber (ACM) is an elastomer obtained by copolymerization of acrylic ester as the main monomer. Its main chain is a saturated carbon chain, and its side groups are polar ester groups. Due to its unique structure, it has many excellent properties, such as heat resistance, aging resistance, oil resistance, ozone resistance, UV resistance, etc. Its mechanical and processing properties are superior to fluororubber and silicone rubber, and its heat resistance, aging resistance, and oil resistance are superior to nitrile rubber. ACM is widely used in various high-temperature and oil-resistant environments, becoming a sealing material that has been developed and promoted by the automotive industry in recent years. It is mainly used as various heat-resistant and oil-resistant sealing rings, gaskets, and oil seals for automobiles and locomotives.
