  • Can a primary plasticiser be absorbed into PVC resin?
  • Primary plasticizers have good compatibility with PVC resin and can be absorbed in large quantities. In special cases as much as 140-150 PHR of Primary plasticiser can be gelated into PVC for super soft products. Nearly all Plasticisers are liquids and have to be absorbed in Suspension resin in heated mixers.
  • What is DOTP plasticizer?
  • The main raw material for DOTP is terephthalic acid and this type of plasticizer fully  complies with modern international requirements for the safety of chemical compounds. DOTP also has a number of  advantages: • expansion  of operating temperatures of cable products from -40 +70 to -45 +80 °C.
  • Why are plasticizers more difficult to process unplasticized PVC (PVC-U)?
  • Plasticizers aid in processing by acting as extenders and lubricants improving the material flow behavior. For this reason, it is more difficult to process unplasticized PVC (PVC-U) which will be our topic of interest.
  • Which PVC films are best suited for blister packaging?
  • They are mainly made available in the lower K value groups, as Unplasticised PVC Foils for Blister Packaging and other Calendered/Extruded Transparent films are best processed from lower K Value grades. Refinements in Suspension resin technology has edged out Bulk PVC in the recent past.
  • What are the most popular plasticizers for PVC?
  • There is a vast array of Primary plasticizers for PVC. This discussion will be limited to the most popular, the Phthalate Esters. Phthalic acid is reacted with various alchohols to manufacture a family of Phthalate plasticizers of which Di Octyl Pthalate (DOP) is the most popular.
  • How do plasticizers work?
  • For example, plasticizers will increase flexibility of the material for a given application, but they will also reduce the viscosity and lower the glass transition temperature (Tg) creating a softer polymer easier to process. Plasticizers aid in processing by acting as extenders and lubricants improving the material flow behavior.
