MICA Band Heaters

A mica core produces a thin, efficient heater.  Heat from the precisely wound resistance element is quickly transferred to the working surface for fast heat-up and response.  Mica provides excellent dielectric strength and heat transfer capability for long heater life.  The mica core is encased in a continuous corrosion resistant sheath and formed.  All full mica band heaters are designed with closed ends to protect against contamination.  Maximum sheath temperature is 800°F.
