  • What is an ester plasticizer?
  • Ester plasticizers contribute processing advantages to rubber compounds made with polar elastomers, much the same as petroleum oils do for low polarity rubbers. By definition, a plasticizer is "a compounding material used to enhance the deformability of a polymeric compound."
  • 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.
  • Are elastomers a plasticizer?
  • Common esters and polymeric polyesters are both external and physical plasticizers. Physical plasticizers may have some weak attraction to the polymer, such as through hydrogen bonding or Van der Waals forces, but, as with external plasticizers, they do not chemically react with the elastomer.
  • 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.
  • Which plasticizers can be used with high polar plasticizer?
  • Chlorinated polyethylene, epichlorohydrin, acrylic and hydrogenated nitrile will accept the highly polar plasticizers but with service temperatures ranging up to 177°C will use smaller quantities and allow a more limited plasticizer choice because of plasticizer volatility characteristics.
  • What are external plasticizers?
  • External plasticizers are materials that interact physically with the elastomer but that do not chemically react 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.
