  • Resistant to sulphur commonly used as a grease additive.
  • Polyacrylate elastomers have good compatibility with higher temperatures up to 149°C (300°F), and even to 177°C (350°F) with some fluids.
  • They should not be used alongside water or other aqueous solutions.
  • Does not perform at temperatures below -40°C (-40°F)
