extraction of plasticized pvc strips with heptane at room temperature (pvc/DOP (black blocks) and pvc/DOP-o-cp52 (solid red circles)). discussion. high plasticizing efficiency of DOP for pvc is attributed to DOP's good compatibility with pvc and its high rate of diffusion in pvc, which result from the interaction between DOP and pvc molecules.
absorption criteria for plasticizers in s-pvc during mixing,rate of diffusion of plasticizers into the pores of s-pvc grain is a kinetic process and is the controlling step during mixing. the absorption of plasticizer in s-pvc grain increases with

recent attempts in the design of efficient pvc plasticizers,dsc studies showed that a blend of pvc with furan dicarboxylates reacted with 1-butanol exhibited similar t g values as pvc/DOP, especially when the plasticizer content was higher than 42,9 phr. t g values of plasticizers with isoamyl alcohol, providing branched alkyl chain in the molecule, were significantly higher than for plasticizers with a
cereplas™ trimellitates are high-quality specialty plasticizers with low volatility, resistance to high temperature, high tensile strength, good electrical properties, and processing ability. while extensively used in high-temperature pvc cable insulation, their fogging performance makes them a natural choice for the automotive industry.

nonmigrating equivalent substitutes for pvc/DOP formulations,hydrophilic oligomers (containing predominantly eo) of molecular weights between 2000 and 5000 g mol-1 exhibit excellent plasticizer efficiency, nearly identical to di-2-ethylhexylphthalate (DOP) in conventional pvc/DOP mixtures and may therefore be used as nonmigrating equivalents for DOP.
- 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.
- 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.
- 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.
- Does DOP elongation increase the tensile strength of PVC films?
- Elongation at break values of PVC films with DOP and different hyperbranched plasticizers were comparable and the tensile strength was slightly higher for new plasticizers than for DOP. The new compounds were characterized with a good thermal stability and improved plasticizer migration resistance.
- Which plasticizer is better DOP or PVC?
- The studies showed that only a PVC blend with HEPCL 8 performed better than DOP in terms of mechanical properties, and at the same time exhibited the highest migration resistance. 2.1.3. Other Branched and Hyperbranched Plasticizers
- Is DOP-o-cp52 a stable plasticizer?
- Flexible samples with 0.32:1 plasticizer over PVC were selected to ensure a high migration rate of plasticizers. These results indicated that the new DOP-like plasticizer in PVC was very stable. Compared to DOP, the larger molecular size of DOP-O-CP52 could obstruct its migration.
