A mica band heater is a cylindrical heating element designed to provide indirect heat to cylindrical surfaces such as in the barrels of plastic injection molding machines, extruders, and other equipment. Mica sheets provide insulation to the heater, where they provide substantial thermal conductivity while also providing electrical insulation. We can highly customize mica band heaters per your specifications.
