Mica band heaters are the ideal solution for high watt density and high operating temperature applications, especially for the plastics industry.Mica band heater can be found in several types of dimensions, wattage, voltages and material.Mica band heater is an inexpensive form of heating solution to external indirect heating. And strip type is also very popular. Mica extrusion machine band heater use electric heating (Ni20Cr80 wire) to heat-up the external surface of drums or pipes and high quality mica material insulated.

To maximize the surface-to-surface contact, our mica heaters are carefully rounded and formed to optimize the grip on a machine barrel. The external metallic protective sheath of Hongtai band heaters is made of a special alloy, which expands less than the barrel when heated. This difference in thermal expansion makes the heater grip the barrel firmly once it is energized. This improves heat transfer which extends the life of the mica band heater.
