Description:

Polyacrylate are copolymers of ethyl or butyl acrylate with a combination of chlorine, acid, amide or epoxy compounds.

Advantages:

Resistance to petroleum fuels and oils, automatic transmission fluid, type A power steering fluid. Good resistance to mineral oil, sunlight, oxygen, and ozone.

Disadvantages:

Cannot be used in alcohol, alkalis, glycol based brake fluids, EP fluids, chlorinated hydrocarbons, gear oils, glycol based brake fluids, hydrocarbons, water or steam (above 275°F), acids and amines. Lower water compatibility, cold flexibility, strength, and compression set resistance than nitrile.
