Product Description

 Insulation material Black mica for electrical equipment and electrical equipment 

Product Description

Biotite mica powder

Biotite powder is a kind of mica which contain more ferrous. Therefore the colour is natural pearlescent black (also have dark brown, reddish brown). Black mica can also strip off into chips, specific gravity of 2.7-3.3, greater than muscovite mica and phlogopite. But it worse in insulation property. In addition it can be corroded and decoloured by strong acid.  

 

Application:

Widely used in decoration materials, rubber products, Brunet coating, release agent and so on.

Specification:

5-10mesh, 10-20mesh, 20-40mesh, 100mesh, 200mesh, 325mesh.

Packing:

20kg/bag, 25kg/bag. (We can also make the package according to customers' request)

 

Note:

If the above specfications can not meet with your needs, please contact us. We can produce according to your request.
