Fumed Silica is also popular as white carbon black and pyrogenic silica. Fumed Silica is non toxic, non-polluting, high-tech inorganic fine white chemical. In high purity fumed silica the silica content is above 99.8%. The particle size varies from 7 to 40 nm. This new ultra-fine inorganic material become a irreplaceable material due to its small particle size, large specific surface area, strong surface absorption, surface energy, heat resistance property.

Production Process:

Fumed silica is made from flame pyrolysis of silicon tetrachloride vaporized in 1800°C electric arc.

Available Grade:

PME-SS-150, PME-SS-200, PME-SS-300, PME-SS-380.
Special request for customization can be prepared.
