Abstract (en)
[origin: WO2022043210A1] The invention relates to a flexible heating element (10) exhibiting a temperature resistance of at least 250°C, in particular of at least 300°C, comprising: - an electrically conductive substrate (15) formed from a metal foil, - an insulation layer (20) formed on at least one side (16) of the substrate (15), and - a heating structure (30) formed on the side (21) of the insulation layer (20) facing away from the substrate (15), wherein the heating element (10) has a heating-element thickness (DH) of less than 1.0 mm, the substrate (15) has a substrate thickness (DS) of 0.02 mm - 0.5 mm, and the insulation layer (20) has an insulation-layer thickness (DI) of 0.2 µm - 30 µm.
