Abstract

Melt flow and viscoelastic behaviour of polypropylene kaolin (PP-kaolin) composites were investigated using a single screw extruder at various filler loading, temperature, extrusion cycle and die diameter. It was discovered that for the effect of filler loading, 5 wt% of kaolin loading has caused MFI value and apparent viscosity of the composites to be slightly reduced with respect to pure PP. Whereas, above 5 wt% of kaolin loading the apparent viscosity started to increase. Experimental results also showed that swelling ratio and MFI decreased gradually with increasing amount of filler loading but unexpectedly at 30wt% of kaolin loading, the swelling ratio started to increase proportionately with shear rate.
