| Abstract | Recycled poly(ethylene terephthalate) (R-PET) flakes obtained frompostconsumer bottles were melt mixed with poly(butylene succinate) (PBS) or withPBS plus ultrafine wollastonite (2000 mesh) at various compositions on a twin screwextruder, followed by injection molding. The tensile properties, morphology, thermalstability and limiting oxygen index (LOI) of the resulting blends and compositeswere evaluated. Among the investigated R-PET/PBS blend compositions (20, 30, 40,50, and 60 wt% PBS), the 60/40 wt% blend exhibited the highest tensile strength andelongation at break, but a lower tensile modulus and thermal stability compared tothose of the neat R-PET. This blend was subsequently blended with different loadinglevels of wollastonite (1030 parts by weight per hundred (phr) of blend resin).According to the tensile testing, thermogravimetric analysis and LOI results, thetensile modulus, tensile strength, thermal stability and flame retardancy of the 60/40wt% R-PET/PBS blend were improved by the incorporation of wollastonite (optimalat 30 phr), while the elongation at break exhibited no significant change. Moreover,wollastonite was effective in preventing melt dripping during combustion of thecomposites. |
