Mica heaters - Import export

Micanite is a kind of insulation paper which is impregnated with a heat resistant binder and afterwards pressed in several shifts under heat and high pressure to plates. This material is heat resistant up to 350 °C, as special construction (Phlogopit) up to 450 °C, and is used for the wire wound formers as well as for the encapsulating cover plates of mica surface heaters. Because of the typical "sandwich"-construction of Micanite Flat Heating Elements and their high watt density it is necessary to use a platen to press the mica heater onto the surface to be heated. Established on the market for round Flat Heating Elements are some standard dimensions (Ø 58 / Ø 65 / Ø 80 / Ø 100 / Ø 160 / Ø 260 mm). But normally Micanite Surface Heating Elements are constructed on customer's request. Mica heaters can be metal sheathed for higher mechanical stability. This makes the heater flexible, so that it is also possible to build a band heater.

Heating bands are the ideal solution for the heating of tubes an cylinders. Mica band heaters, frequently used as nozzle heaters, are made with a plastic-tight stainless steel casing. Such mica heating bands are in many dimension available from stock. The Ceramic heating band type is suitable specially for applications with high watt density and therefore for higher temperatures. Ceramic band heaters, also known as ceramic ring heaters or cylindrical ceramic sectional heaters, are attached to the contact surface by means of a clamping mechanism. A preferred field of use for ceramic band heaters is the heating of plasticising cylinders, bushings and nozzles of injection moulding machines and screw barrels of extrusion machines. For thermal optimization and process control ceramic band heaters can also be offered with insulation jackets or air cooling.
