Thermal and flow properties of perlite‐filled high‐density polyethylenes (HDPE), studied in the first part of the paper, are discussed. Maximum peak temperatures of endotherms ( T mp ) and the corresponding relative peak heights were examined by differential scanning calorimetry (DSC). The data obtained from a Brabender torque rheometer were evaluated to find the melt viscosities at low share rate during preparation of perlite–HDPE composities. The filler concentration, type of HDPEs, and the use of γ‐APS are found to be effective and influential factors on the thermal and flow propertis of these composities. © 1994 John Wiley & Sons, Inc.
