PTC heating sheet principle:
1. PTC heating sheet is composed of PTC ceramic heating component and corrugated aluminum strip by high-temperature gluing.
2. PTC heating sheet has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heater. One of its outstanding features lies in the safety performance, and in any application, the surface "redness" phenomenon of electric heating tube heaters will not occur, resulting in scalds, fires and other safety hazards.
