  • 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.
  • Which plasticizer has a low plasticizing efficiency?
  • Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
  • Can phthalate be used as a secondary plasticizer in PVC?
  • In this study, we attached DOP to chlorinated paraffin (CP), acting as a secondary plasticizer in PVC, to prepare a new compound giving PVC highly plasticization without migration. Unlike other reported methods, our approach covalently attaches phthalate to chlorinated paraffin, a low molecular weight compound with a structure similar to PVC.
  • How much plasticiser can be gelated into PVC?
  • 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. High Speed mixers (which generate frictional heat while mixing) are the most popular types of dryblending equipment.
  • Do polymeric plasticizers have a low plasticizing efficiency?
  • Unfortunately, they did not try them to PVC. In general, their large molecule size hinders diffusion in PVC to suppress migration. However, the rate of diffusion of the plasticizer is one of the most important factors determining plasticizer efficiency 33, 34. Polymeric plasticizer generally has low plasticizing efficiency.
  • What is nonmigrating highly plasticized PVC?
  • Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
