Natural mica sheet is a mica part with certain thickness and shape, which is made of thick mica through peeling, thickness determination, cutting, drilling or punching. This product is suitable for TV, power capacitor, thermal relay, monitoring display, aerospace, aviation, communication, radar, heat-resistant framework sheet, etc. as raw and auxiliary materials. Sub: electric heater chip, electric heater protector, gasket, electronic tube piece and bulb piece. Because their materials are natural mineral products, they have the characteristics of pollution-free, insulation and good voltage resistance. They can cut natural mica sheets of various specifications according to customer needs.
There are many kinds of natural mica. Muscovite and phlogopite are used as electrical insulating materials. Muscovite has glassy luster, generally colorless and transparent; Phlogopite has metallic luster and semi metallic luster, common ones are golden yellow, brown, light green, etc., with poor transparency. Muscovite and phlogopite have good electrical and mechanical properties, good heat resistance, chemical stability and corona resistance. Both kinds of mica can be peeled and processed into soft and elastic flakes with a thickness of 0.01 to 0.03 mm. Muscovite has better electrical properties than phlogopite, but phlogopite is soft and has better heat resistance than muscovite.
According to the application, mica can be generally divided into three types: mica flakes (flake mica), mica for capacitors and mica thick flakes for electronic tubes.
