Specifications
1. manufactory for mica 2.time of delivery is shot 3.no asbestos 4.our price is competitiveMica 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.
Particle Size:
It contains 3-5mm,1-3mm,15mesh,20mesh,40mesh,60mesh,80mesh,100mesh,200mesh,325 mesh ,400 mesh etc.

Application
Applications |
1)Mica can be used as prior filler in paint and coating. |
2)Mica can be applied in protecting layer of welding rods, conducting wires and electric cables. |
3)Mica is also the basic raw material for mica porcelain products. |
4)Mica can be used as suspended substance in fire-fighting dry powder. |
5)Mica can be taken as filler, shelter, lubricating substance, a drawing of patterns in plastics, rubber, asbestos products and sealing materials. |
6)Mica can also be used as filler in degreasing agent of cosmetics, in insulating materials of high-frequent electric waves and acid-durable products. |
7)Mica can be used as coating in models of forecasting metal, the brightening material in aluminum and paint in electroplating. |
