PTC heaters are flexible, printed, self-regulating heaters. While traditional fixed-resistance wire heaters utilize wires or coils to generate heat, PTC heaters utilize Positive Temperature Coefficient materials that exhibit a positive resistance change with an increase in temperature. As the temperature of the heater or the ambient temperature increases, the electrical resistance also increases. In simpler terms, current flows through the heater when it’s cold, and the flow is restricted when the temperature gets hotter.
PTC heating systems offer a range of benefits that far exceed traditional wire or carbon fiber options. PTC heaters heat evenly across the entire surface of the product and self-regulates to a designed temperature, which eliminates the possibility of overheating. These heaters run open-loop without the need for external diagnostics, thermostats, or control units, undeniably improving the safety and efficiency of your product. PTC technology is a must for products that require safer, faster, or more uniform heating.
