Description
Polyacrylates are copolymers (ethyl acrylates) possessing outstanding resistance to petroleum fuels and oils.
Key Uses
  • Sealing automatic transmissions and power steering systems.
  • Sealing petroleum oils up to 300°F.
Temperature Range
Standard Compound: -25°F to +300°F
Hardness (Shore A)
40 to 90
Features
  • With excellent resistance to hot oil, automatic transmission and Type A power steering fluids, the greatest use for Polyacrylate is found in automobile manufacture, where o-rings of this material are employed to seal components of automatic transmission and power steering systems.
  • Highly resistant to sunlight and ozone degradation, Polyacrylate also features an enhanced ability to resist flex cracking.
Limitations
  • While resistance to hot air aging is superior to Nitrile, Polyacrylate strength, compression set, water resistance properties and low temperature capabilities are inferior to many other polymers.
  • Polyacrylates are also not generally recommended for exposure to alcohol, glycols, alkalis, brake fluids, or to chlorinated or aromatic hydrocarbons.
