GLYCERIN AS PLASTICIZER OF PAN - IGTPAN
Advantages of Glycerin in PAN plasticization: It is one of the most highly known polar substances after water. It has a boiling point above the melting temperature of PAN. Totally soluble in water, which facilitates its removal from the fibers. Low toxicity in relation to solvents used for PAN spinning. Totally biodegradable.
Natural-based plasticizers and biopolymer films: A review
Plasticizers are, in general, high boiling point liquids with average molecular weights of between 300 and 600, and linear or cyclic carbon chains (14–40 carbons) [12], [13]. The low molecular size of a plasticizer allows it to occupy intermolecular spaces between polymer chains, reducing secondary forces among them.
Effect of glycerol plasticizer loading on the physical
This research was set out to explore the development of arrowroot starch (AS) films using glycerol (G) as plasticizer at the ratio of 15, 30, and 45% (w/w, starch basis) using solution casting

How to use glycerin as a plasticizer? | ResearchGate
How to use glycerin as a plasticizer? I'm currently working on a collagen structure. As the design requirements demand certain mechanical properties I would like to try a bio-compatible...
- Is glycerin a plasticizer?
- It can be observed by the thermal analysis (DSC) that the incorporation of glycerin in PAN as a plasticizer makes the endothermic peak of its fusion visible and quite separated from the exothermic peak of cyclization, with a difference greater than 150 o C, which would not be possible to observe if it was not present.
- 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.
- Why is glycerol a nontoxic plasticizer?
- Glycerol is a by-product residue from biodiesel production and it is a nontoxic plasticizer. It improves spinnability, reducing the interaction between nitrile groups of the polymer chain, plasticizing the polymer and lowering its melting point, thereby enabling the melt spinning without significant degradation [10, 18 ].
- Can glycerin be used as a polymer electrolyte?
- Copper-ion conducting gel polymer electrolyte (GPE) systems based on polymer poly (vinyl alcohol) (PVA) and copper sulphate salt doped with glycerin as plasticizer have been synthesized by using solution casting technique. Differential scanning calorimetry (DSC) is used to examine the thermal effect of glycerin on a polymer electrolyte.
- 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.
