Natural-based plasticizers and biopolymer films: A review
The council of the IUPAC (International Union of Pure and Applied Chemistry) defined a plasticizer as “a substance or material incorporated in a material (usually a plastic or elastomer) to increase its flexibility, workability, or distensibility”.
GLYCERIN AS PLASTICIZER OF PAN - IGTPAN
Low price on the market ( < US$ 0.2 / kg). Useful properties of glycerin in PAN plasticization Glycerin, glycerol, chemically 1,2,3-propanotriol (C 3 H 8 O 3 ), is one of the known substances with higher polarity.
GLYCEROL DERIVATIVES AS A MODERN PLASTICIZERS
The filmogenic solutions (FS) composed of quinoa starch (4.0g/100mL) were prepared, containing various concentrations of glycerol (GC; 16.6–33.4g glycerol/100g of quinoa starch, dry weight basis
How to use glycerin as a plasticizer? | ResearchGate
Oct 2011. Makoto Kohga. Hydroxyl terminated polybutadiene (HTPB) is widely used as a propellant binder. A plasticizer is usually added to improve the processing properties, the mechanical
GLYCEROL DERIVATIVES AS A MODERN PLASTICIZERS FOR STARCH FILMS
Generally, as a plasticizers glycerine is used. However, also some of polyols, (sorbitol, xylitol) may be used as plasticizers ( Talja et al., 2007) . Furthermore, water sorbed in film acts also as plasticizer. The purpose of this work was to found novel application of glycerol , as plasticizers for starch derivatives films.
- 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.
- 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.
- 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.
- 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.
- Why is glycerine used in PVA plasticization?
- Glycerine (GL), as a traditional plasticizer, is commonly used for PVA plasticization due to its low price and the structure of three-hydroxyl groups . However, a large amount of glycerine tends to leak out during the extrusion process, which is not beneficial for the melt-spinning.
- 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.
