Polyacrylate (ACM) compounds retain their properties when sealing petroleum oils at continuous temperatures as high as 350ºF (175ºC). Polyacrylate seals are used extensively in automatic transmission and other automotive applications.
Polyacrylate materials provide excellent weather resistance, but only fair resistance to water when submersed for extended periods. Polyacrylate also provide fair compression set resistance as well as low temperature performance
PAI offers black ACM compounds in a hardness range of 50 to 80 durometer.
