Mica Powder

Features of Mica

1.  Insulation     
2.  High temperature resistant   
3.  Lustrous appearance
4.  Stable physical and chemical property
5.  Good heat insulation, elasticity and toughness

Type of Mica

 

1.  Muscovite mica: mica powder and mica flakes

2.  Other mica: phlogopite mica, black mica, colored mica
