  • Are DBS and DHS a good plasticizer for PVC?
  • Where data was available, the results from this study are in good agreement with the experiment; we conclude that DBS and DHS are most promising green plasticizers for PVC, since they have properties comparable to DEHP but not the environmental and toxicity concerns. CC-BY 4.0. 1. Introduction
  • Are PVC granules suitable for dry-blend applications?
  • PVC resins (Figure 1. SEM of PVC granules (100micron) used for dry-blend applications) with low K values demonstrate fast fusion behavior, high melt flow rates (MFR), and low contamination levels.
  • Which PVC plasticizer is most commonly used?
  • Traditionally, phthalates are the most widely used PVC plasticizer. (1) In particular, PVC tubes using di (2-ethylhexyl) phthalate (DEHP) are used for external processing of blood and other bio-substances, presenting the concern that DEHP might leach into the blood to cause toxicity.
  • What plasticizers are used in PVC resins?
  • To combat this issue, plasticizers are commonly added to the resin to impart flexibility and thermal stability. (2,3) Traditionally, phthalates are the most widely used PVC plasticizer.
  • Is DEA a good solvent for PVC?
  • DEA is an excellent solvent for PVC as it considerably increases plasticization properties and eases the production process, but DEA leads to high diffusion rates due to its polarity. (54) Increased plasticizer polarity further leads to an increase in the probability of dehydrochlorination, which can lead to the degradation of the PVC system.
  • Which plasticizer reduces Young's modulus of PVC?
  • The E (x) of all plasticized systems converged as the temperature reached 500 K. DBS was the only plasticizer that consistently decreased the Young’s modulus of PVC as well as or better than DEHP (Figure 4). Figure 4. Predicted Young’s modulus for systems of PVC plasticized with DEHP, DBS, DHS, DEA, and 1,4-BDB at temperatures from 150 to 500 K.
