  • 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.
  • Which plasticizers are used in elastomer compounds?
  • Common plasticizers used in elastomer compounds are mineral oils and esters such as phthalates, sebacates, and adipates. However, plasticizer selection is largely dependent on which elastomer (s) is used and what the desired outcome is.
  • 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 do elastomer and plastic polymers need a plasticizer?
  • Elastomer and plastic polymers may be tough, dry or rigid materials that, for many applications, have a need for plasticizers. A plasticizer, among other contributions, will reduce the melt viscosity, lower the temperature of a second order glass transition (Tg) or lower the elastic modulus of a polymer.
  • Which plasticizer is compatible with FKM?
  • TBEP is one such plasticizer that is compatible with FKM. Plasticizer use with ACM is limited dues to the high operating temperatures used. Polymeric plasticizers, TOTM and TBEP can be used in some cases. Both monomeric and polymeric ester plasticizers are compatible with AEM.
  • Which plasticizers are compatible with eco?
  • ECO already has good low-temperature flexibility; however, it can be further improved by addition of plasticizers such as DOA or DBP. Ester plasticizers are compatible with ECO where the plasticizer has a similar polarity to that of the polymer. DOP, DIDP, and, TOTM are common choices.
