Effect of glycerol plasticizer loading on the physical, mechanical
Among the plasticizing agents, glycerol has been used as a plasticizer to produce starch-based films because of its compatibility with amylose 50, which stimulates better mechanical properties...
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.
The effect of glycerol concentration as a plasticizer on edible films
The most widely used type of plasticizer is glycerol (Togas et al. 2017). Various studies have been carried out regarding the making of edible films from hydrocolloid and other gelatin with glycerol as plasticizers. Rusli et al (2017) have conducted research on the manufacture of edible films from carrageenan with glycerol. Setiawan et al
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.
Pharmaceutical formulation analysis of gelatin-based
Various amounts of glycerin (0, 6, 12, 18, 24, 30, or 36 g) were mixed with 60 g of gelatin or succinylated gelatin in a beaker, and 122 g of purified water was added. The mixture was heated in a water bath at 70 °C. The mixture was stirred with a spatula every 15 min for an hour.
- 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 glycerol be used as a plasticizer?
- However, the incorporation of the plasticizer can lead to poor mechanical properties and low thermal stability. In addition, the vast majority of the literature has reported that the incorporation of hydrophilic plasticizers such as glycerol may increase the water solubility and WVP of the film.
- Is glycerol a better plasticizer than sorbitol?
- Although glycerol is a more effective plasticizer based on mass content, the plasticizing efficiency of sorbitol was higher at the molecular basis. Glycerol and calcium chloride (crosslinker) had a synergistic effect on the mechanical properties of the films, and beyond a certain limit they had a deteriorating effect.
- How much glycerol is in a film plasticizer?
- Dunnet's test showed that there is no significant difference between the control and film plasticizer with 10% glycerol, this may be because the amount of glycerol incorporated with this concentration is not sufficient to produce changes in the polymer network. 3.4. Water vapor permeability
- Why is glycerol used as a plasticizer for starch films?
- Among the plasticizers, glycerol has often been used as a plasticizer for starch films due to its compatibility with amylose which promotes better mechanical properties by interfering with amylose packing, thereby decreases the intermolecular forces between the starch molecules [22, 23].
- Is glycerin a better plasticizer than PEG400?
- Glycerin was a better plasticizer than PEG400 and gave more flexibility to the films because of the lower molecular weight of glycerin. WVP of films plasticized with PEG and DEG was lower than that of GLY-plasticized film.
