<p>A body of polymeric material, comprising a core-e.g. of foam plastic-surrounded by a skin of greater density, includes a filler of metallic or other electrically conductive particles distributed throughout the core or at least in an intermediate layer separating an inner part of the core from the skin. The filler particles, preferably consisting of iron or aluminum, are injected together with all or part of the core material during the molding of the body.</p> |
