ACM Polyacrylate ASTM D 2000, SAE J200 Type/Class: DF
ACM or simply acrylate rubber consists of a polymerized ester and a curing monomer. Ethyl acrylate rubber has a good resistance to heat and mineral oil; on the other hand butyl acrylate has a better cold flexibility. Polyacrylate has a good resistance to mineral oil, oxygen and ozone even at high temperatures. The water compatibility and cold flexibility of ACM are significantly worse than with NBR.
|Heat Resistance||Shortened lifetime up to approximately 350°F (177°C).|
|Cold Flexibility||Down to approximately –5°F (–21°C).|
