Interfacial effects of plasticizers on the properties
In this paper, eco-friendly plasticizers, such as glycerin (GL), diacetin (DA), triacetin (TA) and polyethylene glycol (PEG) are necessarily introduced. The plasticizing effect is evaluated by harmonic interface energy between CDA and plasticizer from contact angle test.
Natural-based plasticizers and biopolymer films: A review
The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
Effectiveness of triacetin and triethyl citrate as
It was found that, at a fixed amount of plasticizer (10%), TRI caused reduction of glass transition temperature (Tg) and melt temperature (Tm) in both PVA with the largest reduction in 88% hydrolysed PVA while TEC showed insignificant changes of Tg and slight reduction of Tm suggesting higher effectiveness of plasticization in 88% hydrolysed PVA

Title: A Review on Plasticizers and Eco-Friendly
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887...
- Is triacetin an effective plasticizer for hydrophobic starch based films?
- For hydrophobic starch-based films, triacetin, as a common food additive in the food industry and non-toxic and eco-friendly to human and environment, in the meantime, triacetin has been proved to display effective plasticization for starch esters, is an applicable plasticizer, which have been applied in our previous work [21,23,24].
- What are eco-friendly plasticizers?
- In this paper, eco-friendly plasticizers, such as glycerin (GL), diacetin (DA), triacetin (TA) and polyethylene glycol (PEG) are necessarily introduced. The plasticizing effect is evaluated by harmonic interface energy between CDA and plasticizer from contact angle test.
- Which plasticizers are suitable for CDA?
- Glycerin (GL), diacetin (DA), triacetin (TA) and polyethylene glycol (PEG) were chosen as the green candidate plasticizers for CDA, because they are environmentally sustainable (“eco-friendly”) plasticizers with low toxicity (Lee et al. 2006a, b; Rao and Diwan 1997).
- Which plasticizers are used in plasticization of pegs?
- Due to the insufficient plasticizing effect and thermal instability of PEGs, the other three plasticizers of GL, DA and TA are mainly selected for the following research. Figure 5 shows the tensile strength and the elongation at break of plasticized CDA.
- Can Plasticizers improve water permeability in fish gelatin-sago starch films?
- Al-Hassan and Norziah (2012) separately incorporated two plasticizers, glycerin and sorbitol, into fish gelatin-sago starch films. It is found that plasticizers can improve the dense polymer molecular chain network structure and increase the free volume, which leads to the film is more susceptible to moisture permeability.
- Is tri a good plasticizer?
- A few researchers incorporated TRI or TEC as plasticizer in polymers such as PLA [7, 8] and PVC with reported reduction of glass transition temperature and melting temperature suggesting improvement in flexibility and processibility.
