Fushite Fumed Silica FST-200
FST is a very fine amorphous silicon dioxide produced by Fushite with a diameter between 5 and 50 nanometers. Its surface structure and agglomerated structure after dispersions contributes to viscosity and thixotropy in liquid resins. It is widely used as a reinforcing filler for rubber and elastomeric materials, as well as for fluidization and prevention of caking in powder materials. It can be used in a wide range of other applications thanks to its high level of purity and ultrafine particles.
