Filed Sept. 17, 1969, Ser. No. 858,878 Int. Cl. B44d 1/14 US. Cl. 117-218 No Drawing. 17 Pages Specification An insulated electrical conductor is provided wherein the insulation covering is a polyimide film having a fluorocarbon polymeric coating of PEP or PTFE on at least one surface thereof, and wherein further the insulated conductor has an overcoating or external layer of a blend of between about 10% and about 35% by weight, based upon the total overcoating weight, of PEP fluorocarbon polymeric material and between about 65% and about 90% by weight, based upon the total overcoating Weight, of PTFE fluorocarbon polymeric material; optionally, the overcoating may have up to about 35% by weight, based upon the total overcoating weight, of a pigment. The terms FBI and PEP fluorocarbon material both refer to copolymers of tetrafluoroethylene and hexafluoropropylene, and PTFE refers to homopolymers of tetrafluoroethylene. Representative pigments which can optionally be used in the overcoating include titanium dioxide, cadmium sele nide red and lamp black.
