mica sheet

mica rigid muscovite sheet USE: High-temp insulating plates’s thickness equality, has very good electric performance and machine performance. The long-run working temperature of muscovite flexible plate is 550°C, while that of phlogopite mica plates is 850°C; which is a new style electric heating material, is fitting to valve electrode, insulation brace and insulation gasket, etc. mica plates is mostly used with industry electric cooker, copycat, baker, family oven, electric cooker, electric boiler, toaster, hair dryer, warm air blower, electron iron, micro-wave oven, bread oven, electric iron, electric sanitize cabinet, thermos, main frequency furnace, stove, arc furnace, heater, water heater and so on .
