    Electric Insulation Phlogopite Mica Plate

    Mica is a kind of rock-forming minerals. Its form is platelike or flaky.The colour is variable with the differences of chemical composition. Mainly Fe content increase will make the colour be darker. The characteristics of mica contains: insulation,high temperature resistant,lustrous appearance, stable physical and chemical property,good heat insulation, excellent elasticity and high toughness etc. Muscovite is used in industry mostly, the second is phlogopite.Mica is used widely in building materials industries, fire-fighting industries, fire extinguishing agent, electric welding rod, plastics, electric insulation
