Low Voltage Flexible Silicone Rubber Heaters

An etched foil heater is built by etching foil tracks that conduct electricity laminated between layers of silicone rubber and nylon for strength and durability.  Etched foil as a resistive element is much thinner than wire resistive elements with better heat distribution across the heater's surface.

12 Volt PTC Heaters

PTC Heaters for 12 Volt Circuits Positive temperature coefficient heaters (PTC) are ideal for small places requiring 12 Volt AC/DC power. These micro heaters work at a constant temperature, not requiring additional temperature controls, minimizing circuit components. 12 Volt PTC heaters come in surface, air, or fan heater configurations.  The small PTC ceramic heating element is embedded in the heat conductive case and prewired for connections to the 12-volt circuit.   How does the PTC heater work? The ceramic heating element inside the heater is made by compressing ceramic materials blended for specific characteristics and temperature.  The positive temperature coefficient...
