The effect of lignocellulosic filler types and concentrations on the mechanical properties of wood plastic composites produced with polypropylene having various melt flowing index (MFI)

41015

In this study, the types and loading of lignocellulosic fillers on the properties of different melt flow index (MFI) polypropylene (PP) based wood plastic composites (WPCs) were determined. Olive pirinas and wood flour (Pinusbrutia Ten.) were used as lignocellulosic fillers at the loading rate of 20% and 40%. Composites were produced by mixing wood flour or pirinas, wax, maleic anhydride grafted polypropylene (MAPP) and low or high MFI PP in a high intensity density mixer. The homogenous mixture was extruded using a single screw extruder with five heating zones. Extrudates were pelletized and composite specimens were injection molded. Control specimens were produced without adding any filler. The physical and mechanical and thermal properties were determined. It is stated that there is no effect of the melt flow index on the some properties of wood plastic composite, however; the mechanical properties compensates the values stated as in ASTM D 6662 standards even though it varies according to the types and rates of the fillers.
