  • Are polymeric plasticizers compatible with polarity and viscosity?
  • Past work has generally shown that compatibility and permanence of polymeric plasticizers in NBR is relatable to polarity and viscosity. Saponification value, in spite of what we have found thus far, is considered a measure of polarity for polymeric plasticizers The higher the sap value, the more polar the polymeric plasticizer.
  • Are polymeric plasticizers better than monomeric?
  • Generally, polymeric plasticizers do not provide significant performance advantages over monomerics and are seldom used. Hydrogenated nitrile butadiene rubber (HNBR) is produced by hydrogenating the double bonds of the butadiene component of nitrile butadiene rubber (NBR).
  • Do polymeric plasticizers Rob curative effectiveness?
  • Plasticizers containing double bonds (oleates and tallates) can rob curative effectiveness, as can naphthenic oils. Generally, polymeric plasticizers do not provide significant performance advantages over monomerics and are seldom used.
  • What is the saponification value of a polymeric plasticizer?
  • Saponification value, in spite of what we have found thus far, is considered a measure of polarity for polymeric plasticizers The higher the sap value, the more polar the polymeric plasticizer. PARAPLEX G-30 was expected to have a potentially greater compatibility problem than PLASTHALL P-550, because of its low viscosity and sap. value.
  • Which structural features of plasticizers influence compound low-temperature?
  • Another structural feature of plasticizers that influences compound low-temperature is branching versus linear end groups. Diesters with linear end groups provide better low-temperature than is obtained from branched end groups when both contain an equal number of carbon atoms. The dioctyl groups of the above esters are branched
  • Which plasticizer is best for as-molded specimens?
  • Low-temperature data for as-molded specimens of 34% and 38% [-CN]] was best for compounds plasticized with only monomeric plasticizer (PLASTHALL 4141).
