Recycled poly(ethylene terephthalate) (R-PET) flakes obtained from postconsumer bottles were melt mixed with poly(butylene succinate) (PBS) or with PBS plus ultrafine wollastonite (2000 mesh) at various compositions on a twin screw extruder, followed by injection molding. The tensile properties, morphology, thermal stability and limiting oxygen index (LOI) of the resulting blends and composites were 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 and elongation at break, but a lower tensile modulus and thermal stability compared to those of the neat R-PET. This blend was …
