Abstract

A substantially infusible, porous, non-woven, electrically conductive web comprises uniformly distributed, electrically conductive, carbonaceous fibres and insulative fibres. The carbonaceous fibres have an average fibre length of 1/16 to 7/16 inch and average denier of from 0.25 to 5.0 and comprise 1 to 35% by weight. The insulative fibres comprise at least 50% by weight, and may be cellulosic or of asbestos. Minor amounts of other fibres and fillers such as fibres of cellulose derivatives or glass, metal filaments and flakes, mica flakes, thermoset resins, e.g. phenol-formaldehyde, titanium dioxide and zinc oxide may also be present. The web may be made on a paper-making machine from an aqueous slurry. Electric heating elements may be made by bridging electrical contacts with the sheet of the invention. Electric recording sheets may be made by coating the paper of the invention with a lead thiosulphate coating.
