Abstract
An electrical heater which includes a fabric prepared from electrodes and an elongate resistive heating element which is composed of a conductive polymer, preferably a PTC conductive polymer, to render the heater self-regulating. The fabric is laminated to, and preferably embedded in, a sheet of an insulating polymer, particularly a non-tracking insulating polymer.
