Feldspar FF20

Feldspar FF20 by Boud Minerals is milled crystalline anhydrous sodium potassium aluminum silicate. It is a lightweight mineral filler. Exhibits high dry brightness, high hardness, good heat stability, inertness and easy dispersibility. Provides protection against extreme weathering corrosion, increase in viscosity and wear properties. It is primarily used as an alternative to silica flour because it has good opacity which reduces the requirement of white pigment in light colored formulations. Feldspar FF20 is used in the manufacturing of plastics to improve density, enable buoyancy, etc.
