Mica Plate

HP5 series of rigid heater mica plate is made of muscovite or phlogopite mica paper impregnated with high temperature resistant silicone resin, which is used as supporting insulation for resistance wire heating elements in electric toasters, hair dryers, irons, curlers, electric hot combs, strip heaters, baseboard heaters and for gaskets and other applications with excellent resistance to moisture, thermal and mechanical properties and good electrical properties.
HP5 series flexible heater mica is made of muscovite or phlogopite mica paper impregnated with a heat resistant binder and polymerized by a heat treatment which is used in band and strip heaters, barrier and layer insulation, furnace gaskets and applications with high heat and moisture resistance. It also can be formed into tubular shapes and used as thermal and electrical insulation in hot air guns.
