Polyimide heaters are constructed of an etched foil element of 0.0005” or 0.0001” thickness, which is encapsulated between two layers of polyimide film and 0.001” FEP adhesive. These flexible heaters are available in a variety of shapes, sizes, and wattages. Wattage ratings are 2.5, 5, or 10W/in2 at 115 or 28 V. It’s thin and lightweight profile combined with a high-watt density makes it possible to get precise heat distribution at a low operating cost. |
