Description

Polyacrylates are copolymers (ethyl acrylates) possessing outstanding resistance to petroleum fuels and oils.

Key Uses(S):

Sealing automatic transmissions & power steering systems. Sealing petroleum oils up to 300°F.

Temperature Range:

Standard Compound: -32°C (-25°F) to 149°C (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 ageing 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.
