ABSTRACT:
An electrically conductive composite article is provided having a polytetrafluoroethylene fibril matrix and a predetermined volume. The electrically conductive composite article comprises electrically conductive particles, and electrically nonconductive, energy expanded hollow polymeric particles. The volume percent of the electrically conductive particles is at least 20 volume percent. The electrically conductive composite article is continuously electrically conductive throughout its entire structure. Accordingly, electric current freely flows through the composite article due to the low resistivity of the article. The electrically conductive composite article may additionally include an elastomer material disposed within the article in a discontinuous fashion.
