 A mica core produces a thin, efficient heater. Heat
from the precisely wound Nichrome 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.
