Introduction Video

Definition of PTC heating film

PTC (Positive Temperature Coefficient) heating element is a product which controls temperature according to thermal environment.
The nanoparticles of the carbon paste resin increases the resistance according to the thermal rises. If the temperature rises to a certain level resistance value is increased to control the power and current, and to prevent overheating by reducing the amount of heat generated.
This product can become a third-generation heating film having a function of suppressing power consumption by an economical and safe heating.
(24 hours must elapse before full restoration is possible)

PTC Heating films condition

  • ㆍ During overheating the resistance value, current value, power value should reduce according to temperature change
  • ㆍ If repeatedly used the initial resistance value should be maintained within heat tolerance.

The Advantage of PTC Heating Film

Index 220w/m2 Heating Film PTC Heating Film
Over Heating Risk Risk Lessen Risk
Consumption of Electrical Power No Change of Power Reduce the Consumption power during overheating
The efficiency of warming system Normal Superior efficiency & Safety
* When the temperature of the film changes from 30 ℃ to the current amount, the temperature is controlled, and when it reaches 60 ℃, the amount of current decreases by 10 ~ 30% and lowers the probability of overheating depending on the power (W) of the heating film and local overheating area. ..
