Rapid Heating Mica Heater


These heaters consist of an etched foil element in between layers of flexible mica and operate at high temperatures with quick response times in industries ranging from military to semiconductor to food service. Mica heaters are custom designed to accommodate curved surfaces in many shapes and sizes. This hard working heater meets the requirements of many demanding heating applications.


  • Expansive temperature range from -150°C to a maximum of 600°C
  • Exceptional heat transfer, quick warming and fast thermal recovery time for optimal production output
  • High watt density capability >100/in² (15.5W/cm²) provides faster processing times than conventional mica band heaters
  • Accommodates curved heating surfaces
  • Designed to be clamped to provide excellent heater response time
  • Heat distribution


  • Semiconductor processing
  • Packaging, strapping, and sealing equipment
  • Commercial food service appliances, convection, hot plates and surfaces
  • Injection molding equipment
  • Air heaters
  • Enclosure systems


  • Custom shapes and dimensions to 20” x 46” (508 x 1168.4 mm)
  • Forming methods allow three-dimensional packaging capabilities

Fullchance Mica heaters have superior heating performance while being flexible in one dimension. They consist of an etched foil element sandwiched in between two layers of mica plate and can operate at temperatures up to 500°C.

The insulating material is phlogopite mica infused with a high temperature resistant polymer. The infused polymer helps mica heaters to be formable during the manufacturing process. The final heat curing enhances the rigidity and sets the form.

The excellent dielectric strength and high temperature capability make mica heater a perfect choice for both convection and radiant heating. It can replace the traditional mica band heater in applications where installation space is limited.
