Tween PTC heating film not only maintains the strength of current carbon heating film such as cleanness, ease of construction, and positive effects come from far—intrared rays, but also has implemented the characteristic of PTC (Positive Temperature Coefficient), which can quickly increase the temperature even in low temperature of winter and prevent over-heating of the film, These properties significantly improved the overall heating effect of Tween PTC Heating Film,Current Heating Film also has many advantages but it is exposed to the problem of overheating. This problem is currently controlled by a thermostat; nevertheless, there are still numerous problems caused by malfunction of the thermostat, This kind of problem causes side-effects, such as being scorched by partial overheating or bending the floor, and even leads to conflagration,

However, Tween PTC Heating Film synthesized carbon (the heating unit of the film) with special polymer, Hence, when the heating process continues and increases the temperature, the Heating Film automatically increases the resistance within the carbon proportionally; thus decreases the power consumption, This phenomenon naturally inhibits the malfunction that occurs through overheating,

Tween PTC Heating Film guarantees low cost of maintenance and salety from fire.
