Semiconductive polyolefin formulations are provided which are readily extrudable into films and coatings having low surface resistivity. The formulations of the invention are comprised of a polyethylene resin with 6 to 15 weight percent of a mixture of two different conductive carbon blacks. The conductive blacks have different structures as defined by their BET surface areas and dibutyl phthalate adsorption numbers. The extrudable semiconductive compositions of the invention have complex viscosities of 3000 to 10000 poise and dispersion numbers from 50 to 600. Extruded films having surface resistivities of less than 10 log ohms produced from the above-identified polyolefin compositions are also provided.
