Abstract

A simple and accurate method for determination of filler material density is described. Rice husk ash (RHA) which consists predominantly of silica serves as a filler in polypropylene. The filler density was determined from first principles using a pyknometer. The filler was compounded in polypropylene and the densities of the composites were measured using an electronic densimeter. The measured composite densities agree very closely with theoretical values calculated based on the measured density of the filler material.
