Thermal Corporation's band heaters are made to heat cylinders, such as pipes, barrels, or nozzles of injection molding and extruding machines. Mica band heaters are constructed by winding a resistance wire or ribbon around a sheet of mica, sandwiching that element between two other sheets of mica, and then forming coated steel around the assembly.

Mica-type band heaters have several advantages over other types of band heaters, but the thing that makes them the most used heater in the plastics industry is the combination of reasonable high-watt density capabilities, reasonably high temperature capabilities (900 degrees Fahrenheit), good efficiency, good lifetime and low cost.
