Acrylate rubber

Chemical Name: Alkyl acrylate copolymer
ASTM D1418: ACM
ASTM D2000 / SAE J200: DF, DH, EH
ISO/DIN 1629: ACM

Polyacrylates or simply acrylate rubbers are copolymers having two major components: the backbone (monomeric acid ester of alkyl or alkoxy) and the reactive cure site. ACMs have good resistance to high heat and oil which is better than NBRs. It also good resists oxygen and ozone even at high temperature, but is with poorer water and low temperature flexibility compared to NBRs. Special ACM can improve low temperature flexibility to -40°C (TR10 value) without reducing oil and heat resistance.
