| Printed Polymer (PTC) |
Printed Polymer heaters are based on low resistance printed silver as current distributor. The heat is generated by a number of parallel connected polymer resistors with PTC characteristics (Positive Temperature Coefficient). In most cases the polymer resistor is covering the heater completely and hence gives a very even temperature distribution. The PTC effect makes the heater self limiting and hence hot and cold spots are avoided as the power is generated were you need it. The polymer heater is also very corrosion resistance compared to metal heaters.Heater benefits - Self regulation - Robust design intensitive to small damages - Corrosion resistant - Cost effective at low power and high voltage Typical applications - Rear view mirrors - Floor heating - Waterbed heaters - Low temperature applications, Deicing Download pdf file » |
