Pamica over thick mica plate in high performance of thermal and electrical insulation is designed for electromechanical and thermomechanical applications, made of high quality mica material and high temperature organic silicon resin after melting and laminating process. The long-run working temperature of muscovite mica plate is 550C, while that of phlogopite is 850C, which is a new style electric heating material. It is suitable to used for valve electrode, insulation brace and insulation gasket, also as a replacement for asbestos and other insulating boards for a variety of applications.
