Polyacrylate rubber is a copolymer of ethyl and acrylates.
Good resistance to petroleum fuels and oils at high temperatures
Polyacrylate rubber displays very good resistance to petroleum fuels, oils and grease, even at high temperatures up to 300 °F. Also, polyacrylate rubbers exhibit very good heat aging resistance such as cracking when exposed to ozone and sunlight.
Not resistant to brake fluids, chlorinated hydrocarbons, alcohol or glycols
Polyacrylate rubber does not withstand brake fluids, chlorinated hydrocarbons, alcohol or glycols.
Used in automotive automatic transmissions and steering systems
Polyacrylic rubbers are highly suited to applications needing resistance to petroleum and high temperatures such as automotive automatic transmissions and steering systems.
