Precipitated Silica
Precipitated silica is a synthetic, white, amorphous form of silicon dioxide, with the same chemical composition as sand: SiO2. Its characteristics are determined by its particle size distribution, porosity, specific surface and purity. It is a synthetic material with numerous applications and is fundamental in such diverse areas as pharmaceutical products or ecological tyres.

Aluminium Silicate Ebrosil SA 60
Development of aluminium silicates began when industries started to demand for an alternative, more effective, white filler to titanium dioxide. Since then, there have been an ever-increasing industrial interest in this type of product and it has become a white filler with numerous, varied applications that is used as a raw material in such diverse sectors as the production of paints and printing inks or the rubber and paper sectors.
