The with increasing temperature under the PTC heater

These lightweight, flat and flexible heaters lack applied controls, keeping production costs low. An excellent solution for disposable devices, each PTC heater is custom-designed to the application.

PTC heater systems offer a range of benefits that far exceed traditional wire or carbon fiber options. PTC heaters are an ideal solution for heating applications such as automobile seats, medical patient warming, or wearables. This technology is a must for products require safer, faster, or more uniform heating.

PTC heating elements are composed of PTC thermistors and aluminium housing that are joined by soldering, gluing or crimping. A PTC thermistor is a semiconductor that changes its properties depending on temperature.

The PTC thermistor is also known as PTC resistor, a treated Polycrystalline ceramic based on barium titanate. Specific treatment procedures provide that one can obtain high conductivity in the material at relatively low temperatures. In the low temperature area the PTC thermistor acts as a classical semiconductor with a Negative Temperature Coefficient. When one exceeds the defined reference temperature, resistance increases rapidly with factor.

The ceramics cannot reach flammable high temperatures because the resistance increases with increasing temperature under the PTC heater curve and in this way self-limited the power and energy that can pass through.
