Fumed Silica

DESCRIPTION:

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. Fumed silica has a very strong thickening effect. Primary particle size is 5–50 nm. The particles are non-porous and have a surface area of 50–600 m2/g. The density is 160–190 kg/m3. APPLICATION: • Paints and coatings • Unsaturated polyester resins, laminating resins and gel coats • HTV- and RTV-2K-silicone rubber • Adhesives and sealants • Printing inks • Cable compounds and cable gels • Plant protection • Adhesives and sealants • Chemical mechanical planarization (CMP) • Coatings • Composites • Food additives • Greases • Pharmaceuticals • Printing and packaging • Silicone sealants • Skin and beauty care product *Please refer to our technical for further information. ADVANTAGES • Optimum adjustment of rheology during processing • Reinforcement of silicone elastomers • Thickening of non-polar liquids • Free-flow of foodstuffs and industrial powders • High chemical purity • Excellent insulation properties, even at high temperatures • Conversion of liquids to powders, e.g. pharmaceuticals, cosmetics • Jellification of battery acids • Rheology control of greases and lubricants
