SisiB Silicones SiSiB® FS-0150 Hydrophilic fumed silica
Categories:	Ceramic; Oxide; Silicon Oxide; Other Engineering Material; Additive/Filler for Polymer
Material Notes:	Composition: SiSiB® FS-0150 is a hydrophilic fumed silica with a specific surface area of 150 m2/g. Introduction: Hydrophilic fumed silica is manufactured by hydrolysing volatile chlorosilanes in an oxyhydrogen flame. In chemical terms, the loose white powder consists of highly pure amorphous silicon dioxide. Hydrophilic silica is wetted by water and can be dispersed in water. Hydrophobic silica is produced by the chemical reaction of hydrophilic silica with reactive silanes, e.g. chlorosilanes or hexamethyldisilazane. It has water-repellent properties and is no longer dispersible in water. All untreated fumed silicas are characterized by: High purity Aggregated structure Submicron particle size Low bulk density Hydrophilic surface CAS No: 112945-52-5 or 7631-86-9 EINECS No.: 231-545-4 Information provided by SiSiB Silicones - PCC Group
