Abstract: An improved corrosion resistant cable shielding tape adapted for use in electrical power and communications cables comprising a metal strip having a deformation resistant layer of polymeric resinous material tightly adhered to at least one side thereof, the deformation resistant layer having a deformation temperature of at least about 270.degree. F. The deformation resistant layer resists abrasion and penetration at the temperatures and pressures normally associated with cable manufacture, installation and/or service use. The deformation resistant layer must be tightly adhered to the metal strip to prevent delamination when exposed to a corrosive environment and to the mechanical forces exerted by metal corrosion products, thereby restricting the path of corrosive attack to the exposed metal edges of the shielding tape. Additional layers of polymeric resinous materials may be included in the multilayered structure of the cable shielding tape such as adhesive and/or heat seal layers.

Abstract: A cable shielding tape comprising a metal strip having a first adhesive layer of polymeric resinous material tightly adhered to at least one side thereof and a bond control layer of polymeric resinous material strippably adhered to the first adhesive layer, and plastic jacketed electrical power and communications cables utilizing such shielding tape. The outer plastic jacket of such cables withstands delamination under conditions of normal use but can easily be removed to facilitate the grounding and splicing procedures; the adhesive layer remains tightly adhered to the metal strip for protection against corrosion following the removal of the jacket.

Abstract: The invention pertains to electrical insulation formed from a normally solid, linear olefin polymer containing from about 1 to about 20 percent by weight of chlorine chemically combined therewith, said polymer having a bulk density of from about 22 to about 36 pounds per cubic foot and wherein the individual polymer particles are predominantly in the range of from about 300 to about 800 microns in size, a melt index of from about 0.05 to about 2 as determined by ASTM Test No. D1238, Procedure A and a tensile yield strength of greater than about 1000 p.s.i. The specified polymers have enhanced processability as compared to conventionally used nonchlorinated or highly chlorinated olefin polymers and may be effectively dry blended with additives such as stabilizers, blowing agents and fillers.
