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. Features: Broad temperature range of -150° 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 Each heater ships with one piece of cut and baked ceramic paper for proper installation. If additional pieces are required, please order additional from the Pre-cut Insulators section of the e-store. Typical applications Semiconductor processing Packaging, strapping, and sealing equipment DNA thermocycling Food service appliances Plastics and rubber molding supplemental heat
