ABSTRACT:
Curable conductive rubber blends of (A) a Masterbatch blend of an (a) dispersing component having a limited compatibility with rubber and (b) a conductor selected from conductive carbon blacks and metal powders, is (B) blended with (c) a rubber, and the resulting conductive blend is then cured/molded as desired. The technique provides a method/product uniformly electrically conductive of very low resistivity with quite modest amounts of conductive filler.
