Product name:
Macro-pored silica gel also named as Type C silica gel, is highly active adsorption material, belongs to amorphous material


Appearance:
milky white, glass-like irregular granular, without impurities, allow individual different color particles.


Molecular formula:
mSiO
2·nH2O


Properties:
Insoluble in water and any solvent; non-toxic, odorless, chemically stable, won’t dissolve in any solvent except for alkali and hydrofluoric acid


Characteristics:
the chemical components and physical structure of macro-pored silica gel decided that it has many characteristics that other similar material difficult to replace: high adsorption capability, good heat stability, high chemical stability and mechanical strength and so on.


Including:
(1) Macro-pored lump silica gel  (can be used as cat sand raw material)
(2) Macro-pored bead silica gel  (can be used as cat sand raw material)
