Natural-based plasticizers and biopolymer films: A review
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 [4]. Di (2-ethylhexyl) phthalate (DEHP), also known as dioctyl phthalate (DOP), was introduced in 1930 and has been the most widely used plasticizer since the 1930s.

PAPER OPEN ACCESS Development and characterization of the
Edible film from ginger starch and chitosan with glycerin as plasticizer has been successfully prepared and characterized. The purpose of this research was to produce and characterized of the mechanical properties of edible film from ginger starch, chitosan, and glycerin as plasticizer.
Development and characterization of the mechanical properties
The thermal degradation of material reached 176.9695°C, water uptake of edible film up to 2.5%, and FTIR data shows an interaction between ginger starch, chitosan, and glycerin. It concluded that edible film from ginger starch, chitosan, and glycerin as plasticizer has good mechanical properties and has potential as a packaging.
- What are the advantages of using glycerin in Pan plasticization?
- Another great advantage of employing glycerin in PAN plasticization is because it is very soluble in water, it can be easily removed from the fibers by washing, restoring the fibers to the same composition as the original copolymer, as if they were produced by wet or dry spinning. This way these fibers are suitable for producing carbon fiber.
- Can glycerin be used to extrude PAN fibers?
- Nowadays, the extrusion process of PAN fibers shows potential of cost reduction in relation to the wet spinning method. This innovative technology enables spinning by melting PAN polymer by using glycerin as the primary plasticizer, avoiding the use of highly toxic solvents.
- Can glycerin be used as a primary plasticizer?
- This innovative technology enables spinning by melting PAN polymer by using glycerin as the primary plasticizer, avoiding the use of highly toxic solvents. In the present work, PAN copolymer was copolymerized by conventional aqueous suspension. Its characterization was performed by FT-IR, GPC and DSC analysis.
- Can glycerol be a plasticizer for hydrophilic packaging industry?
- Owing to its hygroscopicity and low volatility, glycerol is competent to be a plasticizer for hydrophilic packaging industry , . The hydrophilic polymers include but are not limited to aliphatic polyester resin, acrylics, PLA, polyurethane, polyvinyl esters, cellulose derivatives, and so on.
- Is glycerol a plasticizer?
- This paper portrays the existing connection between glycerol and the polymer industry, particularly as a feedstock for polymer synthesis and its role as a plasticizer in the starch polymer.
- Can glycerol be used as a plasticizer for extrusion process?
- In the present work, a PAN- co-Styrene copolymer was formulated with 28%/mass of glycerol, which works as a plasticizer, for extrusion process.
