WATLOW's MI band is a high performance heater. Its performance and name are derived from Watlow's exclusive mineral insulation -- a material that has a much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters.
A thin layer of the "high" thermal conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath.
A thicker, "low" thermal conductivity layer backs up the element wire, directing the heat inward toward the part being heated.
The result is more efficient heat transfer -- a performance solution that lowers element wire temperatures and increases heater life.
Application include extruders; blown film dies; injection moulding machines; and other cylinder heating applications.
