Hydrophilic Fumed Silica Powder CAS No.: 7631-86-9 Used For Cosmetics
Fume Silica Powder HL-200 is manufactured by controlled combustion of highly purified chlorosilanes with oxygen and hydrogen. A schematic diagram is given below. The silica generated in the flame is transported to HCL removal process, cooling process, that be made from hydrophilic fumed silica powder.
1, Used as anti-settling, thickening, anti-sagging agent.
2, Improvement of free flow and anti-caking characteristics of powders.
3, Rheology and thixotropy control of liquid systems, binders, polymers,etc.
