  • Are plasticizers and elastomers compatible?
  • The compatibility of plasticizers and elastomers is important. They need to have similar polarities. The Plasticizer/Polymer Polarity Chart on page 22 graphically shows the relationship between compatibility and polarity for esters and elastomers.
  • How do I Choose an ester plasticizer?
  • When choosing an ester plasticizer, consider the specific elastomer being used and its properties. Compatibility between the plasticizer and elastomer is crucial, based on having similar polarities.
  • 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.
  • Are ethylene acrylic elastomers better at low temperature?
  • Recent advancements in ethylene acrylic elastomers by DuPont have pushed this performance to higher temperatures and longer periods of time through their Vamac-brand VMX 5000 series of polymers. Low temperature improvements, however, are traditionally achieved through the addition of high performance ester plasticizers.
