Muscovite Mica (theroretical Chemical formula=KAI2(AISi3O10)(OH)2) is a complex aluminosilicate minerals that have a sheet or plate-like structure with remarkable cleavage parallel to the direction of the large surface that allows it to be split or delaminated into thin films that are transparent, flexible, elastic, and tough. It has an outstanding physical, chemical, electrical, thermal and mechanical properties which are not found in any other products either natural or synthetic.

PHYSICALLY : Mica is transparent, optically flat, colourless, resilient and incompressible. It is waterproof and moisture-proof.

CHEMICALLY : Mica is a complex hydrous silicate of aluminium containing potassium and traces of several other elements. It is stable and practically inert (except to hydrofluoric acid and concentrated sulfuric acid) and virtually unaffected by the action of heat, light, water, oil, solvents, alkalis and other chemicals.

ELECTRICALLY : Mica has a unique combination of high dielectric strength and a uniform dielectric constant. It is therefore able to withstand exposure to electrical discharge without oxidizing and serves as an excellent insulator.

THERMALLY : Mica is infusible and non-combustible and has low heat conductivity and is not affected by extended exposure to electrical discharge without oxidizing and serves as an excellent insulator.

MECHANICALLY : Mica is relatively soft, flexible elastic and tough having high tensile and flexural strengths and modules of elasticity.
