  • 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 plasticizers are used with Hycar 4052?
  • Plasticizers used with Hycar 4052 for low-temperature flexibility and permanence and heat and fluid aging resulted in the rearrangement of plasticizers from most to least effective as A1100, DB(3E)A, DADEG and DBEESS. The following conclusions are apparent from the testing of the two plasticized acrylic compounds.
  • What is the least permanent plasticizer order after heat aging?
  • Coupling this with the unaged low-temperature flexibility and the knowledge of the Vamac B-124 MB shown earlier, the most to least permanent plasticizer order after heat aging is A1100, DADEG=DBEESS and DB(3E)A (Table V).
  • 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.
  • Can Plasti-cizers be used in vamac compounds?
  • While many of these plasti-cizers have been used in Vamac compounds to great effect in the past, the need for performance at higher temperatures necessitates the development of new materials to improve on permanence and volatility.
  • 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.
