Abstract
A conduit formed of extruded polymeric material, which outer surfaces are continuously intrinsically lubricated by a reserve of active lubricious agents which migrate outwardly from within the composition to such surfaces.
Claims5
A polymeric composition containing a suspension of lubricious material within a zone having a significantly higher concentration of said lubricious material than that in the areas adjacent said zone that continuously migrates from said zone to the surface of said composition, thereby to continuously replenish lubricious material removed from said surface.
A conduit, having an outer and inner wall, for receiving lengths of cable to be drawn through said conduit, said conduit being comprised of a polymeric composition containing a suspension of lubricious material within a zone having a significantly higher concentration of said lubricious material than that in the areas adjacent said zone that continuously migrates from said zone to the outer and inner wall of said conduit, whereby when the lubricious material is removed from the said walls, the lubricity of said walls are continuously replenished.
