Abstract
The composition contains exfoliating graphite and a carrier which is preferably polyvinyl chloride, polyethylene or polypropylene. The composition can be produced by co-extrusion of a suitable mixture with a further plastics material to form composite products in continuous lengths. The products include papers, tubes, fuel, pipes, doorstrips, electrical conduit and electrical cables.
