Polyacrylate Rubber (ACM) appears as a light-colored to amber elastomer. Key features include exceptional resistance to hot oils and transmission fluids, excellent heat aging properties, good resistance to ozone and weather exposure, low-temperature flexibility, and good compression set characteristics. ACM finds specialized applications in automotive transmission seals, engine gaskets, o-rings, oil seals, and industrial components.
ACM competes with FKM fluoroelastomers and HNBR. The industry is trending toward developing grades with improved low-temperature performance and processing characteristics. Various subtypes exist based on the acrylate monomer composition and crosslinking systems, including diamine-cured types, soap-cured versions, and other specialty versions.
