Organic esters of plasticizers affecting the water absorption
The effects of four organic esters used as plasticizers (triacetin, diethyl phthalate (DEP), dibutyl phthalate (DBP) and tributyl citrate (TBC)) on the water absorption behavior and adhesive property of Eudragit films and on the glass transition temperature (Tg) and plasticizer permanence of Eudragit E film were investigated.

A review on organophosphate esters
Introduction. Organophosphate esters (OPEs) are derivatives of phosphoric acid and are widely used as flame retardants and plasticizers in the world because of their good physiochemical properties and excellent flame retardancy and plasticizing effects, added into a variety of commercial and industrial products, such as electronic equipment, paints, textiles, furniture, and flooring and

- Does plasticizer affect water vapor permeability of cassava starch films?
- Films without plasticizer adsorbed less water and showed higher water vapor permeability, indicating the antiplasticizing effect. Other study also investigated the effect of sucrose or inverted sugar addition on mechanical properties, hydrophilicity and water activity of cassava starch films was studied .
- 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.
- 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.
- 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 .
- What types of plasticizers are used in hydrophilic polymers?
- In addition to water, the most commonly used plasticizers are polyols, mono-, di- and oligosaccharides. Polyols have been found to be particularly effective for use in plasticized hydrophilic polymers .
- What is the difference between hydrophobic and water insoluble plasticizers?
- In contrast, hydrophobic plasticizers may close the micro-voids in the film, leading to a decrease in water uptake. However, water insoluble plasticizers can cause phase separation leading to flexibility losses or yet to the formation of discontinuity zones during film drying.
