Silica gels are a form of silicon dioxide, SiO2, the same material that occurs in nature as sand. Silica gels are highly porous adsorbents containing an enormous internal surface area on which certain materials are selectively adsorbed. Silica gel is a kind of highly active amorphous adsorptive substance with stable chemical properties. Different micro-porous structures can be achieved by using different manufacturing processes. In application,
Silica Gel Applications
A-type silica gel fine pore |
Capable of high adsorption capacity at low humidities dew-point temperature: - 40C – 70C |
B-type silica gel |
High adsorption capacity at high relative humidity. Used where humidity needs to be controlled. |
Silica Gel Al2O3 |
Alumina stabilized Silica Gel resistant to free water and shattering. |
Blue silica gel |
Indicating Silica Gel. Changes from Blue to Pink as it gets water saturated. |
Silica gel desiccant tablet |
Used for drying medicines and food products. |
DL blue silica gel |
Shows a color change with quantitative adsorption of water. |
FNG silica gel |
Water resistant Silica Gel. Resistant to shattering. Used for air dehumidifying and as a buffer desiccant in regular dessicant grade silica gel units. |
