<p>Extruded or injection-molded plastic moldings, especially containers, have a resistance below 10 8>ohms, preferably not more than 10 4>ohms, and a screening effect for electromagnetic radiation. At least half of the material used in the molding is recycled, especially polyethylene or polypropylene containing at least 10wt% of aluminum. Independent claims are included for: (A) a method for making the moldings by shredding or granulating recycled material, adding material which increases its electrical conductivity and extruding or injection molding the product; and (B) use of recycled material to produce conductive moldings which have a screening effect for electromagnetic radiation.</p> |
