Abstract

A composition of solid particles comprising substantially inorganic, electronically conductive particles and fluoropolymer particles, wherein the fluoropolymer is melt-processable and has a melting point between 100° C. and 325° C. and a melt flow index at 372° C. and at 5 kg load (MFI 372/5) of at least 0.1 and up to 100 g/10 min, and wherein the fluoropolymer particles have a particle size of less than 500 nm and wherein the particles comprising the substantially inorganic, electronically conductive material is present in the form of particles having a particle size of less than 15,000 μm, and methods for producing such compositions and articles containing such compositions.
