  • How to choose an ester plasticizer?
  • The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will help in selecting an ester plasticizer. ASTM D883, "Plastics Nomenclature," American Society for Testing and Materials, Philadelphia, PA.
  • Do fluorocarbon elastomers accept ester plasticizers?
  • Fluorocarbon elastomers will accept a relatively wide range of ester plasticizers, but here, with both the high temperature post cure and application temperatures ranging to 232°C, they find use only at very low levels for processing. The selection of an ester plasticizer can often be confusing because of the large choice available.
  • Why are ester plasticizers important for elastomers?
  • Ester plasticizers make it possible to process elastomers easily while also providing flexibility in the end-use product. Plasticizer–elastomer interactions are governed by many factors, such as solubility parameter, molecular weight and chemical structure.
  • 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.
  • 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.
  • Which plasticizers are used in combination with specialty monomeric esters?
  • Flame-retardant plasticizers, phosphate esters and chlorinated paraffins are often combined in usage with flame-retardant plasticizers frequently used in combination with specialty monomeric esters. Both materials are inefficient plasticizers, thus explaining their combinations with specialty monomerics.
