  • 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.
  • Which plasticizer is best for chitosan film?
  • Besides, considering the plasticization efficiency and storage stability for chitosan films, GLY and PEG showed to be more suitable than EG and PG. Furthermore, a plasticizer concentration of 20% (w/w) with GLY or PEG was sufficient to obtain flexible chitosan film, exhibiting good stability for 5 months of storage.
  • 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).
  • What is the tensile strength of a plasticizer?
  • The tensile strength was approx. 19 MPa, while the elongation at break was approx. 250% for all tested plasticizers at a concentration of 50 PHR. Furthermore, plasticizer migration studies showed that the synthesized plasticizers had excellent resistance to plasticizer leaching.
  • 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 effective is a plasticizer?
  • The effectiveness of a plasticizer depends on the molecular weight of a plasticizer and the ratio of individual components in a molecule, i.e., polar groups, non-polar polarizable groups, and non-polar non-polarizable groups [ 68 ].
