  • What is the difference between DOTP & TOTM plasticizers?
  • Purity. If processed in truly dedicated equipment, DOTP can be produced nearly free of DEHP contamination. DOTP plasticizer producers specify a DEHP content of less than 50 parts per million, but almost all shipments contain significantly less than that. By contrast, TOTM can contain as much as 2,000 ppm of DEHP and is never free of it.
  • Does DOTP craze better than TOTM?
  • “DOTP may cause more crazing than TOTM but resists crazing better than other alternative plasticizers and even better than DEHP. TOTM is also outperformed in this regard by polymeric plasticizers. Over the years, moreover, device manufacturers have avoided serious crazing issues with DEHP through appropriate design and other measures.
  • Are alternative plasticizers safe for flexible PVC medical compounds?
  • While phthalate esters such as DEHP are the most widely used plasticizers for flexible PVC medical compounds and have been for 50 years, issues concerning their possible effects on human health have caused some device manufacturers to consider compounds containing alternative plasticizers. Sometimes the pressure to do so is considerable.
  • Which plasticizers are compatible with PVC?
  • from the surface of a fully processed compound. The loop test (ASTM D3291-74) observes plasticizer compatibility with PVC du ing compression and while under tensile stress. Jayflex DINP and DIDP exhibit better compat
  • Which plasticizer is tolerant of the use of secondary plasticizers?

  • Which plasticizers are more volatile than terephthalates or cyclohexanoates?
  • compared to terephthalates or cyclohexanoates. Alternative plasticizers such as adipates, di-benzoates or citrates are substan ially more volatile than Jayflex DINP and DIDP.*DINP and DIDP are restricted in the EU based on precautionary grounds in toys and chil
