Phlogopite with high dielectric strength and greater resistance, low dielectric loss and anti-arcing, corona resistance and other excellent dielectric properties, and hard, mechanical strength, high temperature and rapid temperature changes and with acid alkali, good physical and chemical properties, therefore, widely used in the radio industry, aviation industry, motor manufacturing, it is widely used in coatings, paints, plastics, linoleum, paper, oil drilling, decorative make-up, etc., can be reduced in the paint ultraviolet light and heat or other damage to the paint film to increase the coating acid, alkali and electrical insulation properties, improve the coating of frost resistance, corrosion resistance, toughness and density, reduce the permeability of the coating to prevent spots and cracks. Gold mica powder can also be used in roofing materials, from the warm rain, heat, etc., gold mica mixed with mineral wool resin paint, do concrete, stone, brick exterior decorative effect, mica pieces for linoleum, pipeline mortar, cementing agent; in rubber products, gold mica do lubricants, release agents, and to do high-intensity electrical insulation and heat, acid and alkali products fillers.
