ACM
ACM, or acrylate rubber, is a synthetic rubber made by copolymerizing acrylate monomer with a small amount of cross-linking monomer.
Material Profile
Acrylate rubber (ACM) is a specialty synthetic rubber made by polymerizing acrylate as the main monomer. Its core strength lies in its excellent resistance to high temperatures and petroleum-based oils, and its ability to work stably in high-temperature oily environments up to about 150°C. ACM also has excellent ozone and weathering resistance. However, its disadvantages are also more obvious, mainly in the form of poor low-temperature resistance, lower elasticity, and a significant drop in performance in hot water or water vapor environments.
application scenario
Based on its high-temperature oil resistance, ACM is mainly used in transmission systems in the automotive industry. It is a commonly used material in the manufacture of oil seals, O-rings, gaskets and hoses in automobile automatic transmission and power steering systems, and can effectively prevent the leakage of high-temperature lubricating oil. ACM is also used as a sealing material in some industrial equipments which require heat and oil resistance but not low temperature and water resistance, in order to ensure the long term reliable operation of the equipments under harsh conditions.
