Precipitated Silica (amorphous powder and granule,silicon dioxide)We provides excellent silica for rubber, tyre, papermaking.
Precipitated Silica (amorphous powder and granule , silicon dioxide)
Common property:
It is a white amorphous powder and granule that dissolves in caustic alkali and hydrofluoric acid. It does not dissolve in other acids, water and other kind of melting agents. This product can be used in soles, tire, silicon rubber, plastic, painting and medicine
Packing: PP/woven bag, EVA/woven bag, kraft paper bag
