Abstract: In an aspect, a circuit material comprises a multilayer stack comprising alternating layers of a reinforcing layer and a fluoropolymer layer; wherein the fluoropolymer layer comprises a fluoropolymer other than a biaxially-oriented polytetrafluoroethylene; wherein the reinforcing layer comprises a biaxially-oriented polytetrafluoroethylene; and wherein an electrically conductive layer is in direct physical contact with an outer surface of the multilayer stack. In another aspect, an article comprises the circuit material. In yet another aspect, a method of making the circuit material comprises laminating the multilayer stack and the electrically conductive layer to form the circuit material; or laminating a layered stack comprising the conductive layer and alternative layers of the fluoropolymer layers and the reinforcing layer to form the circuit material.

Abstract: In an embodiment the dielectric layer comprises a fluoropolymer, a plurality of boron nitride particles, a plurality of titanium dioxide particles, a plurality of silica particles; and a reinforcing layer. The dielectric layer can comprise at least one of 20 to 45 volume percent of the fluoropolymer, 15 to 35 volume percent of the plurality of boron nitride particles, 1 to 32 volume percent of the plurality of titanium dioxide particles, 10 to 35 volume percent of the plurality of silica particles, and 5 to 15 volume percent of the reinforcing layer; wherein the volume percent values are based on a total volume of the dielectric layer.
