What is PTC Heating Film?

The PTC means Positive Temperature Coefficient, it refers to kinds of specia materials, the electrical resistance of the PTC materials will increase when the temperature of the material is raised, and also the electrical resistance of the material will reduce when the temperature is reduced.

The PTC heating film is a new type and updated warm floor product based on the ordinary heating film.

Temperature limiting function of electric heating film. The working principle is that if the temperature rises, the resistance will increase, so that the current will decrease, and the temperature will not increase endlessly. Conversely, if the temperature drops, the resistance will decrease, the current will increase, and the temperature will not decrease endlessly. Thus, the temperature is controlled within a safe and reasonable safety range. To achieve the effect of energy saving and power saving.
