  • 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
  • Can bio-based plasticizers compete with DEHP in PVC?
  • Potential alternatives to DEHP in PVC include diheptyl succinate (DHS), diethyl adipate (DEA), 1,4-butanediol dibenzoate (1,4-BDB), and dibutyl sebacate (DBS). To examine whether that these bio-based plasticizers can compete with DEHP, we need to compare their tensile, mechanical, and diffusional properties.
  • Does DBS increase the flexibility of PVC?
  • We expected DBS to substantially increase the flexibility of PVC due to its two aromatic rings whose polarity increases the interaction with the PVC backbone. Indeed DBS and DHS were the only plasticizers that lead to a lower Young’s modulus than DEHP at room temperature (∼298 K). (15)
  • What are alternative plasticizers for polyvinyl chloride (PVC)?
  • Environmental and toxicity concerns dictate replacement of di (2-ethylhexyl) phthalate (DEHP) plasticizer used to impart flexibility and thermal stability to polyvinyl chloride (PVC). Potential alternatives to DEHP in PVC include diheptyl succinate (DHS), diethyl adipate (DEA), 1,4-butanediol dibenzoate (1,4-BDB), and dibutyl sebacate (DBS).
  • Does 1-4-bdb plasticize PVC?
  • DBS was the only plasticizer to consistently lower the G ( T) of PVC as well as or better than DEHP. 1-4-BDB continued to exhibit anomalous behavior that suggested an inability to plasticize PVC (at least at this concentration). Figure 6.
  • 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.
