Kapton Heaters: Polyimide Etched-Foil Heating Elements
A Kapton heater earns its place wherever heat has to be added without anyone noticing the heater. The element is an etched metal foil sealed between two thin layers of polyimide film, so the finished part is only 0.2 to 0.3 mm thick and weighs almost nothing. It sits flat against a battery cell, an optical mount, a wafer chuck or an instrument wall without adding bulk and without holding warmth once the power is off. The foil does the heating and the film stores hardly any energy, so the part reaches temperature in seconds and follows a controller closely. That response, together with the very low outgassing of polyimide, is why these heaters turn up so often in vacuum, semiconductor, medical and battery work.
The range on this page is our standard program: a set of fixed sizes, two output levels and two backing options, all running on 12 V DC. It covers the parts most applications need off the shelf. When a standard part will not do, we build to drawing instead, with different shapes, higher surface loading, higher temperatures and mains voltage. If your part is in the range, order it. If it is not, the range is the place to start the conversation about the one you actually need.
