Macro-pored Micro-spherical Silica Gel


Molecular formula :

White, transparent or translucent spherical particle.

Internally well-distributed micro-pored structure, physically and chemically stable.
Good thermal stability, High mechanical strength Have strong adsorption capacity to water vapor and other gases and solvents.

Used as catalyst or catalyst carrier in the manufacturing of the important industrial products, such as cyanuramide, benzene anhydride, maleic acid anhydride, butadiene rubber, acrylic nitrite, etc. It is also widely used for highly refining petrochemical products by adsorbing aromatic hydrocarbon. It may also be used for the selectively adsorptive separation of organic gases and liquids, as well as for eliminating multivalent poisonous elements in water through ion exchanging process.
