Abstract

Rheological studies of wood polymer composite (WPC) with polypropylene (PP) matrix containing 50 wt % wood flour have been performed. Several procedures for determination of WPC viscosity curves with a limited number of melt flow rate (MFR) measurements using universal Vinogradov-Malkin, two-parameter Ostwald-de Waele power-law and three-parameter logarithmic Klein equations were presented. The plastometric tests of WPC were carried out to determine the viscosity curves. It has been stated that the discussed procedures can be useful in engineering practice to rapidly assess the rheological properties of wood polymer composites.
