ABSTRACT:
An electrically conductive article comprises an insulating material, preferably polyurethane or a similar plastic material, with a plurality of thinly coated electrically conductive fibers dispersed randomly and uniformly therethrough. The fibers are thinly coated with a lubricating cohesive silicone oil or equivalent material which adheres to the fibers and repels the insulating material, thereby preventing encapsulation of the fibers and rendering the coated fibers mutually attractive to define conductive paths through the article even at extremely low fiber loadings.
