Mica is a natural material, in nature the most common type of mica is muscovite. Mica has been used in construction and cosmetology. Ground mica is used for the production of roofing materials, refractory paints, thermal insulation of steam boilers and pipelines, steam and refrigeration units, and as a filler in plastics.
