Highly electrically conductive polypropylene (PP) composites were prepared by melt mixing using tin–lead (Sn‐Pb) alloy as conducting fillers. Two Sn‐Pb alloys, Sn‐Pb (20/80) and Sn‐Pb (40/60), were used for comparison. The effects of Sn‐Pb loading and molding temperature on electrical conductivity and mechanical properties of composites were investigated. It was found that both factors had significant effect on electrical conductivity of the final Sn‐Pb/PP composite. It was interesting to observe that the molding temperature could control the formation of long‐range conducting paths. The mechanism has been explored through the nonequilibrium phase behavior of Sn‐Pb alloy. The influence of Sn‐Pb loading on mechanical properties of Sn‐Pb/PP composites was also investigated. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
