Polyacrylates or Acrylate polymers belong to a group of polymers which could be referred to generally as plastics. They are noted for their transparency, resistance to breakage, and elasticity.
Acrylic elastomer is a general term for a type of synthetic rubber whose main component is acrylic acid alkyl ester (ethyl or butyl ester).
Major characteristics of acrylic rubber include good heat resistance and oil resistance, it can endure a temperature of 170 ~ 180 ℃ under dry heat or in oil. Since it does not have a double bond, acrylic rubber also boasts of good weatherability and ozone resistance.
However, its cold resistance is not very good.
Polyacrylate is used mainly for oil seals.
