  • Are plasticizers environmentally friendly?
  • Four environmentally friendly plasticizer samples were obtained; their chemical structures and compositions were confirmed by gas chromatography (GC) and infrared spectroscopy (FT–IR) analyses, and their physicochemical properties and thermal stability (TGA analysis) were investigated.
  • What is the best plasticizer?
  • The best migration test result obtained was 70% lower than that for DEHP or DINP. The ester mixture that was found to be the most favorable plasticizer was characterized by good thermal and thermo-oxidative stability (5% weight loss temperature: 227.8 °C in air and 261.1 °C in nitrogen).
  • Are plasticizers better than DINP and DEHP?
  • Moreover, the physicochemical and mechanical properties of soft PVC samples suggested that in this study, plasticizers had the same efficiency as DINP and DEHP. Furthermore, plasticizer migration studies showed that the synthesized plasticizers had the best compatibility and plasticizing effects.
  • Do natural plasticizer mixtures reduce the dependence on petroleum-based plasticizers?
  • Moreover, since they were produced from renewable, environmentally friendly, biodegradable, and readily available raw materials, the natural plasticizer mixtures will reduce the dependence on petroleum-based plasticizers. According to the obtained results, all evaluated samples exhibited adequate soft PVC properties.
  • Can plasticizers replace petroleum-based plasticizer in PVC applications?
  • Compared to DINP and DEHP, the migration was as much as 70% lower for each plasticizer concentration. Thus, due to their good compatibility, efficiency and thermal properties, the plasticizers synthesized in this research have the potential to replace petroleum-based plasticizers in PVC applications.
  • Which PVC plasticizer is best for biodegradation?
  • DHS was found to be the best PVC plasticizer, which is a compromise between longer molecules favorable for plasticization and shorter molecules favorable for biodegradation.
