Mineral Insulated (MI) Band Heaters

High Performance Heater—More Efficient Heat Transfer

The MI band heater from Watlow® is a high-performance heater. The band heater's 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” thermally conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, “low” thermally conductive 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 band heater life.

features & benefits


High thermal conductivity of MI and low mass construction provides rapid response to temperature control and avoids thermal lag

Operating temperatures up to 1400°F (760°C) allows safe melting of resins such as PEEK™, Teflon®, Ultem® and Zytel®

Higher watt densities contribute to faster heat-up and throughput for increased productivity

Stainless steel cover and side fold design resists contamination from overflow of plastic or other free-flowing materials

Attached clamp bars eliminates cumbersome clamping straps, making installation easier
