Vitreous silica

Vitreous silica (CAS 60676-86-0), also sold as silicon dioxide or silica, is an amorphous, non-crystalline form of SiO₂ produced through high-temperature fusion. It functions as a rheology modifier and stabilizer.

This versatile material acts as a flow control agent across a broad range of industrial and consumer product formulations. In coatings, adhesives, and sealants, it controls viscosity and prevents sagging.

It improves thixotropic behavior in both solvent-borne and waterborne systems. Rubber compounders incorporate it as a reinforcing filler and processing aid, contributing to dimensional stability in molded profiles.

Food and personal care manufacturers use approved grades as an anti-caking agent and carrier in powdered products. This includes everything from seasoning blends to various pressed cosmetic powders.

In agriculture, it functions as a flow conditioner in granular pesticide and fertilizer formulations. This reduces clumping during storage and handling to ensure consistent application in the field.

The product is supplied as a fine white powder in a range of particle sizes and surface area specifications. These are tailored to meet specific end-use performance requirements for various industries.

Food-grade material is available to FCC and E551 specifications for use in food and feed applications. These standards ensure the highest level of safety and compliance for consumers.

Technical and fumed grades are also commercially available for industrial coating, rubber, and polymer applications. These grades provide the necessary structural integrity for demanding manufacturing environments.
