ABSTRACT:
Compositions comprising a polyolefin polymer and an expanded graphite exhibit uniform conductivity over a broad range of temperature. In one embodiment, the polyolefin polymer is polypropylene or polyethylene homopolymer or a polypropylene or polyethylene copolymer. The compositions provide uniform conductivity and can be used as a conductive formulation for medium and high voltage cable components.
