The MI band heater from Watlow® is a high-performance heater. Its performance and name are derived from Watlow's exclusive mineral insulation—a material with much higher thermal conductivity than 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, which lowers element wire temperatures and increases heater life. 

• Gives an almost instant response to temperature control
• Eliminates thermal lag and temperature overshoot associated with ceramic knuckle heaters

Operating temperatures up to
1400°F (760°C)

• Allows safe melting of resins such as PEEK™, Teflon®, Ultem® and Zytel®

• Contributes to faster heat-up and throughput for increased productivity

• Resists contamination from overflow of plastic or other free-flowing materials

• Eliminates cumbersome clamping straps, making installation easier
