  • Which plasticizer is used to improve the mechanical properties of PLA?
  • (32,34,37)Specifically, to improve the mechanical properties of the PLA, TEC, a nontoxic, eco-friendly, and natural plasticizer, has been widely used. (37−42) In recent years, natural cellulosic fibers have been combined with polymers for the production of low-cost and high-performance materials.
  • Does high plasticizer content affect ductility?
  • However, in blends with high plasticizer content, a lack of miscibility also occurred with increased mol. wt. Theor. results were comparable with those obtained exptl. at compns., which were miscible. Increasing plasticizer content increased the ductility and decreased the strength of the polymer.
  • Which plasticizer is best for food contact?
  • (31−36)Among them, citrate ester-based plasticizers are widely used because of their good miscibility with the PLA and their biocompatibility, ideal for food contact applications. (32,34,37)Specifically, to improve the mechanical properties of the PLA, TEC, a nontoxic, eco-friendly, and natural plasticizer, has been widely used. (37−42)
  • Are biopolymers a good substitute for conventional plasticizers?
  • 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.
  • Can citrate esters be used as plasticizers with poly(lactic acid) (PLA)?
  • (Wiley) Citrate esters were used as plasticizers with poly(lactic acid) (PLA). Films were extruded using a single-screw extruder with plasticizer contents of 10, 20, and 30% by wt. All of the citrate esters investigated were found to be effective in reducing the glass transition temp. and improving the elongation at break.
  • Do multiple plasticizers increase crystallinity of PLA?
  • At. force microscopy (AFM) was used to analyze the morphologies of the blends. Multiple plasticizers were effective in lowering the glass transition temp. (Tg) and the melting temp. (Tm) of PLA. Moreover, crystallinity of PLA increased with increasing the content of multiple plasticizers.
