Extrusion Foamed Poly(lactic) Acid/Polypropylene Blended
Original language description
Poly(lactic) acid (PLA), as an alternative sustainable bio-based polymer, have been extensively introduced for polyemr foaming processes nowadays. Several modification methods are utilized for the improvement of foam morphology, expand foaming window, and as well as the prhysical properties. In this study, PLA is physically blended with polypropylene (PP) with several concentrations and subsequently foamed using supercritical carbon dioxide (SC -CO2) as a blowing agent. Different foaming temperature ofbatch control system pressure. From the experimental results, neat PLA presents the highest expansion ratio while PLA//PP blended foams show relatively low expansion ratio. SEM images indicate micro-cellular foam morphology of the blends which could be caused by high melt strength of PP. Moreover, an isotropic foam structure was described by isotropic foam index. In addition, the compatibility of prepared PLA/PP blends is revealed by thermal properties measurement.
