Hydrated
Silica
Precipitated Silica
|
Hydrated silica has two types, one is precipitated silica and
another one is fumed silica according to difference production
method, which is a fine and special chemical product with white
color. The main composition is SiO2 .Hydrated Silica is indissoluble,
Thermo stable, Non-flame, Non-pollution. Electric insulation and
parable. It is mainly used as rubber strengthening agent and additives.
It can be used to manufacture white, transparent rubber products.
Hydrated silica is also widely used in the industries of plastic,
Paint, ink, Paper, Pharmaceutical, Daily chemicals and food because
of its non-toxicity and smelless.
SinoSi¡¯s Hydrated
silicas (precipitated and fumed) are going to be widely used in
the world market upon to its good physical properties and stable
chemical components, which can be import substitutes of Germany
Degussa and American Cabot in China market. And we also have some
stable users in the oversea market for our above precipitated
and fused silicas.

Fumed
Silica Materials
Characteristics
Fumed Silica is one type of hydrated silica materials
which is a fine and special chemical product with white color.
The main composition is SiO2 .Hydrated Silica is indissoluble,
Thermo stable, Non-flame, Non-pollution. Electric insulation
and parable. It is mainly used as rubber strengthening agent
and additives. It can be used to manufacture white, transparent
rubber products. Hydrated silica is also widely used in the
industries of plastic, Paint, ink, Paper, Pharmaceutical, Daily
chemicals and food because of its non-toxicity and smelless.
SinoSi¡¯s Fumed Silica is a white and colloidal micro-particle
with primary micro-particle from 5-40 nm and has obvious properties
such as thixotropy, reinforcing, thickening and filling etc.
and is insoluble in all kinds of solvents and liquids except
hydrofluoric acid and concentrated bases.
SinoSi¡¯s Fumed
Silica is widely used in the world market dependent on its good
physical properties and stable chemical components, and also
to be as an import substitutes of Germany Degussa and American
Cabot company¡¯s products in China market.
