Abstract: A metal-plastic-metal structural laminate which can be formed into various useful articles having compound curves using conventional metal forming techniques. The laminate comprises two metal skin layers and a centrally disposed polymer layer comprising a core layer, and optionally first and second adhesive layers. Each metal skin layer is 2 to 20 mils, the ratio of the core thickness to skin thickness is less than 9:1 and the total laminate thickness is 5 to 65 mils. The laminate can be bent to 90.degree. to a critical radius, the distance between the pivot point and the inner skin surface of the laminate, without metal rupture.

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: Markedly improved flame retardance is imparted to crosslinked olefin polymers containing halogenated organic moiety by incorporating therein elemental red phosphorus. The resulting flame retardant compositions are particularly useful in fabrication of crosslinked olefin polymer foams.
