Abstract
A heat-shrinkable electromagnetic interference (EMI) shielding jacket sheathable over a generally elongate object of a given outer diameter extent. The jacket is formed of a tubular outer member of an indefinite length and an expanded inner diameter which is greater than the outer diameter of the object, an electrically-conductive inner member received coaxially within the outer member and extending coextensive therewith, and a generally continuous, thermoplastic interlayer interposed between the outer and inner members and extending coextensive therewith. The interlayer bonds the inner member to the outer member along substantially the entire length thereof for consolidating the jacket into an integral structure. The outer member, in turn, is heat-shrinkable to a recovered, i.e., contracted inner diameter smaller than the expanded inner diameter for substantially conforming the jacket to the outer diametric extent of the object.
