Mica heaters are efficient and economical solutions to the heating requirements of many applications. Mica heaters can attain a maximum sheath temperature of 900°f, but with different electrical termination styles, clamping mechanisms, and ability to accommodate holes and cutouts, mica band heaters are successfully used in many applications, but are mostly sought for in the plastics industry.
Mica heaters are different types of top grade mica. The thickness of each mica layer is carefully selected in order to balance between the insulating characteristics of mica and the ease of heat transfer from the heating core to the machine barrel.
The resistance wire ribbon used in a "fragma" mica heater is not restricted to the capabilities of nichrome wire. Different alloys are considered for different applications. The internal winding is carefully designed to ensure uniform heat distribution throughout the band heater. 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 bucan 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.
