  • 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).
  • Why are plasticizers replaced with a compatible & non-toxic ester plasticizer?
  • To avoid the negative effects caused by plasticizer migration and at the same time maintain the good properties of soft PVC, low-molecular-weight plasticizers were replaced with compatible and non-toxic ester plasticizers.
  • How are plasticizers characterized?
  • The produced plasticizers were characterized by GC, TGA, FTIR, and physicochemical properties. Their plasticizing performance was mainly evaluated by the analysis of physicochemical properties, mechanical properties, and plasticizer migration of the soft PVC samples and was compared with those of the commercial plasticizers DINP and DEHP.
  • Are epoxidized esters a PVC plasticizer?
  • The chemical structure of the main compounds of the proposed mixture of epoxidized esters of succinic acid, propylene glycol, and oleic acid as a PVC plasticizer. For the obtained plasticizer samples, GC, FT–IR, and TGA analyses were performed and the physicochemical properties were determined.
  • 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.
