7.Uses
The Fumes Silica and Precipitated Silica we produced is used widely in many areas, such as the shoe making, tyre industry, viscose-increasing agent for toothpaste, additives for foodstuff and medicines, and anti-inflammation agent in hygiene and fire-proof materials, etc.
Accordingly, the specification of that will be different. The Surface Area of the Precipitated Silica ranges from 100 to 230m2/g and the Average Particle Size ranges from 400 meshes to 2500 mesh. And the BET for the Fumed Silica ranges from 0 to 400 m2/g.
