An experimental study was carried out to investigate the flow behavior and the viscosity of mica flake‐filled polypropylene melts and the mechanical properties of mica‐polypropylene composites. The properties of the molded composites exhibit moduli which are higher than most filled polymers. Tensile strength values are noticeably improved when a silane coupling agent or a carboxyl‐modified polypropylene is employed, although the extent of improvement is not great. A high processing temperature helps to minimize flake damage and to improve flow orientation of the flakes.
