 Watlow MI Band Heaters  




 MI Bands Offer High Temperature Operation and Long Life


Product Spec Sheet



 The MI Band is a high performance heater. Its performance and name are derived from Watlow's exclusive mineral insulation material that has much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters.
A thin layer of the "high" Thermal conductivity used to MI material is 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 towards the part that is being heated. The result is more efficient heat transfer... a performance solution that lowers element wire temperatures and increases heater life



  • Heater operating temperatures to
    1400F (760 C)
  • Watt densities to 230 W/in2
    (35.6 W/cm2) available on small
    diameter nozzle bands
  • Watt densities to 100 W/in2
    (15.5 W/cm2) available on large
    diameter barrel bands
  • Operating temperatures to 1400F (760C) make it possible to safely melt even the newest resins, like PEEk, Teflon®, Ultem® and Zytel®.
  • Higher watt densities than any other band contribute to faster heat-up and through-put to increase productivity High thermal Conductivity of MI and low mass construction give almost instant response to temperature control This performance solution eliminates thermal lag and temperature overshoot associated with ceramic knuckle heaters.
  • Stainless steel cover as well as side fold design resist contamination by overflow of plastic or other free-flowing materials.
  • Side folds turn to the inside diameter rather than the outside diameter.
  • Permanently attached clamp bars eliminate cumbersome
    clamping straps, which makes installation easier.
