Pamica flexible mica sheet for heater consist of approximately 90% muscovite or alternatively phlogopite, impregnated with high temperature resistant organic silicon resin. It is used as insulating parts which need to be rolled into cylinder shape with its good plasticity for hair dryers, micro-wave ovens, electric irons and electric toasts, also used as gaskets of automotive industry by a replacement for asbestos, and in other appliances and applications where excellent resistance to moisture, thermal and insulation properties are required. The products are certified by UL and in conformity with IEC371.
