3.Mica's main advantages are insulativity and heat resistance, which are perfect:
1). If mica's thickness reaches 0.015mm, its average breakdown voltage would be 2.0—5.7kV, puncture strength would be 133- 407KV/mm.
2). When mica is heated by temperature of 100-600°C, its elasticity and surface properties will not change.
(1) Used in decorating, paint and coating.
(2) Mica powder is the basic raw material for mica ceramics products.
(3) It can be used in fire-fighting dry powder, protecting layer of welding rods, conducting wires and electric cables.
(4)It can be taken as a filler, shelter, lubricating substance, drawing of patterns in plastics, rubber, asbestos products and sealing materials. It can also be used as a filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid-durable products. It can be used as coating in models of forcasting metal, the brightening material in aluminium and paint in electroplating bath.
