Effects of molecular design parameters on plasticizer
Abstract. Using all-atom molecular simulation, a wide range of plasticizers for poly (vinyl chlorid) (PVC), including ortho- and tere-phthalates, trimellitates, citrates, and various aliphatic dicarboxylates, are systematically studied. We focus on the effects of plasticizer molecular structure on its performance, as measured by performance

In PVC gloves produced in earlier times, phthalate plasticizers were used by 80% among the overall plasticizers, including DOP, DBP, DIBP, BBP, DINP, etc. DOP is called an all-round plasticizer because of its advantages of high plasticization performance, good PVC compatibility, low exudation, low volatility, softness, high brightness, etc.

- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- Does plasticizer type affect the equilibrium moisture content of films?
- Plasticizer type did not significantly affect the equilibrium moisture content of films. Sucrose added films were the most fragile at low RH, while GLY films were the most hygroscopic. However, at RH of 76–90%, sucrose films showed similar resistance compared to other plasticized films.
- When did plasticizers start?
- Later, in 1912, triphenyl phosphate was tested to substitute camphor oil, representing the beginning of the ester plasticizers era. Phthalic acid esters found applications as plasticizers for the first time in 1920 and continue to be the largest class of plasticizers in the 21st century .
- What percentage of plasticizer demand is DOP?
- DOP represents 50% of world plasticizer demand Source BASF estimates Petrochemicals – Industrial Petrochemicals N-CPN/I The Heart of Your Products
- What happens if a plasticizer exceeds a critical concentration?
- Above a critical concentration, the plasticizer can exceed the compatibility limit with the biopolymer, and phase separation with plasticizer exclusion is usually observed . Usually, biopolymers and plasticizers are hygroscopic and therefore film moisture content is affected by ambient conditions.
- Do plasticizer concentration and hydrophilic nature affect moisture affinity of cassava starch films?
- Plasticizer concentration and hydrophilic nature were found to be important factors in determining the moisture affinity of cassava starch films . GLY-containing films adsorbed more water and at a higher rate during their storage, compared to sorbitol films.
