Fumed Silica By Vasu Sales Corporation

Cab-O-Sil M-5 (Fumed Silica) is powder that are available with either hydrophobic or hydrophilic surface. The versatility of our CAB-O-SIL fumed silicas is due to key product attributes, such as high surface area, surface chemistry, aggregated structure, and purity, all of which lead to excellent performance.
Fumed silica
(CAS number 112945-52-5)
Also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler.
Applications: Fumed silica serves as a universal thickening agent and an anti caking agent (free-flow agent) in powders. Like silica gel, it serves as a desiccant. It is used in cosmetics for its light-diffusing properties. It is used as a light abrasive, in products like toothpaste. Other uses include filler in silicone elastomer and viscosity adjustment in paints, coatings, printing inks, adhesives and unsaturated polyester resins. It is also used in the production of cat litter box filler.
