Precipitated amorphous silica

Precipitated amorphous silica (CAS 68855-54-9 ) is a synthetic, high-purity silica manufactured through a wet chemical process. It is distinct from naturally mined diatomaceous earth products such as Kieselguhr or Celatom FW 20. It functions primarily as a rheology modifier, anti-caking agent, and reinforcing filler across a broad range of industrial and consumer formulations. In coatings and printing inks, it controls viscosity and prevents settling. The material delivers matting effects in both solvent-borne and waterborne systems. Adhesive and sealant formulators incorporate it to adjust flow behavior and improve thixotropy in silicone and polyurethane systems. Food manufacturers use it as an anti-caking agent in powdered ingredients, spice blends, and dry mixes. This helps to maintain flowability during processing and packaging for various food applications. Pharmaceutical producers rely on it as a glidant and carrier in tablet and capsule manufacturing. This improves powder flow on high-speed production lines and ensures consistent dosing in medical products. Precipitated amorphous silica is supplied as a fine white powder in a range of particle sizes. Food-grade material is available to FCC and E551 standards for global compliance. Pharmaceutical-grade is supplied to USP and Ph. Eur. specifications to meet strict regulatory requirements. Technical grades are also available for industrial coating and adhesive applications.
