PTC heating foils

PTC heating foils

The operation of PTC heating foils is based on the PTC effect. This means that the resistance of the heating foil increases as the temperature rises. Because of this property, the temperature is “self-regulated” by the foil itself. The foil is made up of multiple polymer resistors with PTC properties. Since the entire foil is constructed from these polymers, there are no hot spots or cold spots. An additional advantage is that the polymer heating foil is highly corrosion-resistant.
