Mica Thermofoil™ Heaters

Mica Thermofoil™ heaters consist of an etched foil element sandwiched between layers of mica. Installed by clamping to heat sinks, mica heaters provide the ultimate temperature and wattage capability for fast warmup.


  • Broad temperature range of -150º to 600°C provides faster processing and cycle times for greater production output
  • High watt density capability to 110 W/in² (17 W/cm²) provides faster processing times than conventional mica strip heaters
  • UL certification is available which can save time and money for end-use UL device recognition
  • Heaters are suitable for vacuum use after initial warmup

Typical applications

  • Semiconductor processing
  • Packaging, strapping, and sealing equipment
  • DNA thermocycling
  • Food service appliances
  • Plastics and rubber molding supplemental heat
