Ethylene acrylate rubber (AEM) is divided into binary rubber and ternary rubber. Binary rubber is composed of ethylene (E)/methyl acrylate (MA), while ternary rubber is composed of E/MA/monomer (CS) providing vulcanization position. Binary rubber can only be vulcanized with peroxide, while ternary rubber can be vulcanized with amine vulcanizing agents due to the presence of a third monomer that provides the vulcanization position. When used for continuous vulcanization of cables using high-pressure steam, ternary rubber can also be vulcanized with peroxide. Ethylene acrylate rubber has excellent high-temperature and heat-resistant mineral oil, hydraulic oil, weather resistance, and low-temperature performance, but is not resistant to low aniline oil and polar solvents.
