HEIZELEMENT,INSBESONDERE MIT GROSSER HEIZFLAECHE

The heating element, intended in particular for the heating of large heating areas, has an inner, electrically conducting layer (2), containing electrodes (3), and outer, electrically non-conducting layers (1). To achieve a greater stability of the characteristic electrical values and a high mechanical strength of the heating element, the electrodes (3) are arranged in the electrically conducting layer (2), which consists at least of a polyester resin composition containing at most 10% by weight of carbon black, referred to the amount of polyester resin, in the form of a metal network or carbon-fibre network or of a perforated metal foil in the same form as the heating element. The electrically conducting layer (2) and the insulating layers (1) are reinforced with glass fibres (4).
