As mica crystals have almost perfect bottom cleavage, they can be stripped into very thin sheets with elasticity.                             
Mica is also a chemically inert substance with acid, alkali and chemical stability.                                
Another important property of mica is its good heat and sound insulation performance.                                
Mica possesses superior electric insulation performance.                                
Mica is resistant against ultraviolet ray, vapor and salt penetration.                                
Mica has special glosses.
