  • What is a reactive ester plasticizer for elastomers?
  • Reactive Ester Plasticizer for Elastomers Stephen O’Rourke, Technical Director, Industrial Ester plasticizers are traditionally used to provide low temperature and improved processing of elastomers. New esters have been designed recently to improve the permanence of these materials when subjected to high heat and fluid extraction.
  • Are plasticizers effective in reducing low-temperature elastomer test values?
  • Plasticizers, when added to acrylic elastomer compounds, can reduce the low-temperature test values obtained compared to unplasticized compounds. Of the monomeric plasticizers tested, DB(3E)A and DADEG appear most effective. It should be noted these are the highest molecular weight of the monomeric esters tested.
  • Are standard polymeric elastomers suitable for low temperature performance?
  • Standard polymeric esters are well known for their permanence in these elastomers, but are insufficient at im-proving low temperature performance. The esters tested in this study are lower molecular weight esters that have high heat resistance, but provide much needed low temperature flexibility, both before and after high heat-aging.
  • Why do we use plasticizers for elastomers?
  • Plasticizers are commonly used only for their as molded low-temperature contribution. Effective plasticizers for the above-named elastomers should have resistance to volatility and extraction at elevated temperatures. Weight changes and low-temperature flexibility after laboratory aging are indicators of plasticizer permanence.
  • Which monomeric plasticizer is most effective?
  • Of the monomeric plasticizers tested, DB(3E)A and DADEG appear most effective. It should be noted these are the highest molecular weight of the monomeric esters tested. The low viscosity (and molecular weight) of polymeric A1100 appears to offer low-temperature flexibility and permanence suitable to acrylic elastomers.
  • What are external plasticizers?
  • External plasticizers are materials that interact physically with the elastomer but are not chemically reacted with the polymer. Solvent and non-solvent are two distinct types of external plasticizers. Common esters and polymeric polyesters are both external and physical plasticizers.
