Mechanical properties of tale and calcium carbonate filled PVC

The main objective of this investigation was to study and compare the thermal rigidity, thermal stability, and processability of poly(vinyl chloride) (PVC) composites filled with single fillers of talc and uncoated ground CaCO3 (SM 90) or a hybrid filler consisting of talc/SM 90. To produce the comp...
