Clay Desiccant is a natural occurring porous mineral which has been dried to produce an absorbent material. It refers to a family of smectite clay primarily composed of purely natural magnesium-calcium montmorillonite, which is produced by a special technology named semi-calcination.
It has excellent moisture adsorption capacity and can prevent the product in the well closed container form the negative effect of moisture.
