Pyrogenic silica, also known as fumed silica manufactured in a flame pyrolysis process, is a thickening and anti-caking agent capable of enhancing the performance, handling and stability of formulations during all aspects of the manufacturing process. The three-dimensional of pyrogenic silica, or fumed silica, induces viscosity-increasing thixotropic behavior when utilized as a thickening agent or reinforcing filler.
As a leading pyrogenic silica distributor in the United States and throughout North America, you can trust Brenntag to supply a high-quality product backed by a host of valuable business services.
Many Industries Benefit From Using Pyrogenic Silica
The cosmetics and personal care industry is a primary user of pyrogenic silica. Its light-diffusing abilities make it an excellent choice for various cosmetic products, and it also serves well as a mild abrasive in toothpaste. In addition, it adjusts the flow properties of liquids and facilitates the free flow of powders.
Other industries able to benefit from pyrogenic silica include printing, for the manufacturing of inks, as well as producers of insulating gels, insulation pads, synthetic and natural rubber materials, silicone elastomers and adhesives. Yet another industrial pyrogenic silica application is as a desiccant due to its effectiveness as a drying agent.
Pyrogenic Silica Chemical Properties
Pyrogenic silica consists of non-porous particles containing microscopic silica droplets fused into chainlike, three-dimensional secondary particles. These then form into tertiary particles, producing a powdery material featuring a high surface area (50–600 m2/g) and low-bulk density (160–190 kg/m3). The powder exhibits viscosity-enhancing properties when used as a thickening agent. Pyrogenic silica shows a space-filling particle structure related to a high surface area and lacking micropores. These characteristics enable fumed silica to act as a free flow additive in powder-like solids, as a thickener in various liquids and as a powerful reinforcing filler in elastomers.
Pyrogenic silica does not pose any health issues to manufacturing personnel or end-users. The Occupational Safety and Health Organization and other regulatory bodies do not list the material as a carcinogen. However, the inhalation of airborne particles can cause respiratory system irritation.
