Silicone Heating Bed Round Heating Element High Thermal Efficiency

These heaters utilize chemically etched circuits which are laminated between thin sheets of silicone to give even quicker heat transfer properties for applications that require precise temperature control. While etched foil circuits need wider widths to accomplish equivalent resistance of a wire, the traditional print/etch process that has been used in printed circuit board fabrication for decades provides tight spacing control which enables spacing between elements to be as tight as 0.004”. The ability of our design teams to create the precise circuit geometry allows even thermal distribution and precise repeatability through production.

Silicone rubber heaters using an etched foil circuit can provide twice the output wattage of the older wire wound technology. This technology allows us to provide multiple heating zones on the same heater and is also attractive for designs that require watt densities greater than 5 W/in2. in as the foil thickness for the circuit can range from 0.0005” to 0.004”.
