ACM

 Acrylic rubber (hereinafter referred to as ACM) is an elastomer obtained by copolymerization of acrylic ester as the main monomer. Its main chain is a saturated carbon chain and the side groups are polar ester groups. Due to its special structure, it has many excellent characteristics, such as: heat resistance, aging resistance, oil resistance, ozone resistance, UV resistance, etc., its mechanical properties and processing properties are better than fluorine rubber and silicone rubber, and its heat resistance, aging resistance and oil resistance Better than nitrile rubber. ACM is widely used in various high-temperature and oil-resistant environments, and has become a sealing material that has been developed and promoted by the automotive industry in recent years, especially for high-temperature oil seals, crankshafts, valve stems, cylinder gaskets, hydraulic oil pipelines, etc., used in automobiles. Almost all demand depends on imports.
