Mica parts are punched from pressed mica sheets which is made of high quality mica mine and high-performance organic silicon resin after melting and laminating process. It has been widely used in electric insulation and heat resistance applications, typical applications include electrical engineering, induction ovens and the household appliances such as microwave ovens, hair dryer, hand dryer etc.
Mica tube is formed by muscovite paper or phlogopite paper fixed with silicon resin, and processed by roll form.
