Thanks for you interests about Precipitated Silica and Fumed Silica. For all time, we have the best price for Precipitated Silica and fumed silica. And I believe our high quality goods with sound prices can earn you market competiveness. 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 **0 to **0m2/g and the Average Particle Size ranges from **0 meshes to ***0 mesh. And the BET for the Fumed Silica ranges from 0 to **0 m2/g. The Fumed Silica is manufactured according to our country’s national standard. Compared with the following three tables of specification, you can find the counterpart fumed silica is as good as AEROSIL***0, CABOSIL, WACKER HDK-N*0 and some items of our fumed silica is superior to those from AEROSIL***0, CABOSIL, WACKER HDK-N*0.
