​​​​Free Flow Agents​


In bulk powder applications, maintaining a free-flow behavior during processing is critical in order to minimize down time and ensure product quality and homogeneity.

Free-flow describes the ability to maintain the powder velocity once it is in motion. In this respect, Grace's SYLOID® and PERKASIL® silicas act as free-flow agents and serve the following functions:

          • Prevent packing of particles and acts as a physical barrier when mass is moving
          • Coat and smooth the edges of bulk powders reducing inter-particle friction
          • Adsorb excess moisture from the atmosphere before it can be absorbed by the bulk powder

Grace silicas are of high purity, chemically inert, and are very efficient in ensuring free-flow, even for the most troublesome powdered food products.

PERKASIL® silica is suitable for a broad range of applications in the consumer and agricultural markets as an anti-caking and free flow agent for food/feed additives and nutrients as well as dietary minerals and salts, liquid carrier and free-flow aid for vitamins, cosmetics, flavors and fragrances, edible oils and fats.

SYLOID® FP silica excipients are a multi-functional excipient for pharmaceutical applications, and recommended as a glidant, tabletting-aid and carrier for personal care and pharmaceutical products. It is available in a wide range of grades to meet a variety of formulation requirements. 

SYLOID® silica excipients are recommended as general purpose, high performance anti-caking, free-flow, and carrying agents for food and industrial applications. A combination of high pore volumne and large internal surface area makets them extremely efficient for these applications. It is available in a wide range of grades to meet a variety of formulation requirement.

To select the right free-flow agent for your product or process, consult your Grace representative.​
