  • 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.
  • 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.
  • Is DOP a good plasticizer?
  • Plasticizing efficiency of DOP is considered as “1” and efficiency all other plasticizers is evaluated with reference to DOP. Besides, cost of DOP based compound can be reduced by blending it with CPW of appropriate grade in appropriate proportion (70:30), without affecting quality of product. However, DOP is on its way out due to health concerns.
  • 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.
  • Can chlorinated paraffin be used as a secondary plasticizer?
  • Although it has limited compatibility with PVC, chlorinated paraffin as a secondary plasticizer may have a stronger interaction with PVC than other secondary plasticizers because it has a chemical structure similar to PVC. In this study, DOP and chlorinated paraffin were chemically combined into a new compound, DOP-O-CP52.
  • Can a 1:1 plasticizer be used for soft PVC products?
  • However, the system with 1:1 plasticizer over PVC had a Tg below 0 °C, indicating that the system was completely flexible at room temperature and could be used for soft (flexible) PVC products. Variation of glass temperature with content of DOP (black stars) and DOP-O-CP52 (red blocks).
