Non-swelling mica

We produce two types of non-swelling mica: fluoro-phlogopite and potassium tetrasilisic mica. Fluoro-phlogopite is transparent pure crystal. By grinding the crystal, it can get tabular formed particle powder with high aspect ratio. The powder is used for resin filler, ceramic material, paint compounding agent, and other applications. We also offer PDM-5B, which has high aspect ratio compared with the other fluoro-phlogopite products, and PDM-800, a special grade of our matt-tone products.

 

PDM-K(G)325 , which is produced by grinding potassium tetrasilisic mica(crystal) , has soft texture feeling and can be used for a paint compounding agent and solid lubricants.

Property table of fluoro-phlogopite

* Particle size is a representative value obtained by laser diffractometry.

Property table of potassium tetrasilisic mica

* Particle diameter is representative value as measured by laser diffraction

Swelling mica

We produce two type of swelling mica: sodium tetrasilisic mica and sodium hectorite. Both are characterized by a composition of large having a high aspect ratio.

 

These products are highly effective as filler with barrier properties.
When its made into sol through swelling with water, both types have properties of low viscosity and low gel. Also, these can be made high concentration sol.
