Used when heat is needed on a flat surface, but when it is impractical to bore a hole in the plate. The flat mica heater allows heat to be distributed evenly across the surface. A much higher watt density can be achieved using these heaters than with silicone rubber mat heaters. 280°C maximum operating temperature. The heaters are best suited for fitting between 2 metal surfaces where one or both require heating, they should be adequately clamped for heat transfer and to prevent premature failure.
