SWHC partners with leading US manufacturers to offer MI heater bands that are manufactured in the USA from high temperature mineral insulation materials capable of reaching operation temperatures up to 1400 F° with maximum watt densities up to 150 watts/inch². The band is a high-performance heater capable of meeting process requirements for engineered grades of plastics. The heater's superior performance and name are derived from the mineral insulation material which provides higher thermal conductivity than the mica and ceramic constructions commonly used to manufacture conventional heaters. Constructions include contamination proof stainless-steel sheaths with heavy duty wire terminations. More consistent, stronger connections, contamination resistant construction and high temperature capabilities lead to less downtime and less headaches for maintenance and production.
Features and Benefits
- High thermal conductivity and low mass construction provides rapid response to temperature control and avoids thermal lag.

- High watt densities up to 100 Watts/inch² for fast heat-up and increased productivity.
- Stainless-steel Sheath construction resists contamination from overflow of plastic or
- Made in the USA – Standard Delivery 3 weeks, Expedited within 1 week.
- Durable 100% Nickel wire and TIG welded terminations deliver durability.
- Flexible design that is customizable-holes, cut-outs, slots, and partial coverage designs.
MI Band Applications:
- Plastic extruders.
- Injection molding machines.
- Laboratory Applications
- Any high temperature cylinder heating application.
Our Manufacturers
Tempco Electric
The Tempco MI-Plus® mineral insulated band heater is the solution for applications that require high watt densities (W/in2) and/or high operating temperatures. Mi-Plus band heaters are capable of temperatures up to 1400°F (760°C) and watt densities up to 150W/in2 (23.25W/cm2). Specially formulated mineral insulated tape provides excellent thermal conductivity and dielectric strength insulating the nickel chrome resistance wire from the stainless-steel sheath. The heater assembly is formed under pressure to a precise diameter with a thin low-mass cross section, assuring fast heat-up rates and reduced cycle times.
Chromalox
Mighty-Tuff™ mineral insulated band heaters provide high watt density and high temperature capabilities up to 1200F (650C) for challenging industrial applications requiring fast start-ups and higher operating temperatures. Mighty Tuff™ heaters are used widely used on plastics machinery processing high temperature engineered grade resins.
Watlow
The mineral insulated (MI) band heater from Watlow® is a high-performance heater that incorporates Watlow’s exclusive mineral insulation. This material offers much higher thermal conductivity than mica and hard ceramic insulators that are used in conventional heaters.
