Explanation

Also known as acrylic rubber, it refers to rubber composed of acrylate homopolymer or elasticity copolymer containing a small amount of monomer with crosslinking active group. polyacrylate rubber has excellent oxidation resistance and ozone resistance due to its saturated main key structure. At the same time, it contains polar side groups, so it has excellent resistance to swelling of hydrocarbon oil. This kind of rubber is usually used at temperatures ranging from -17 ° C to 204 ° C, and performs well at high temperatures. Compared with acrylonitrilebutadiene rubber, natural rubber, and general-purpose butadiene rubber, its performance is slightly different. However, polyacrylate rubber is inferior to other types of rubber in some aspects, such as its tensile properties, processing properties, cold resistance and water resistance are relatively poor, and vulcanization is relatively difficult. Therefore, it is more suitable for manufacturing rubber parts that require high temperature and oil resistance, pipes and container linings that are exposed to oil for a long time, and rubber parts exposed to ozone and harsh weather.
