Sillica Gel is avai lable in porous, granular, and amorphous form, synthetically manufactured from
the chemical reaction between sulfuric acid and sodium silicate. The internal structure of Silica Gel
is composed of a vast network of interconnected microscopic pores which attract and hold water ,
alcohol , hydrocarbons and other chemicals by the phenomena known as physical adsorption and
capillary condensation.

Use
Static adsorption by removing of moisture and control of humidity in the package and other
enclosed spaces without induced air flow. Dynamic adsorption by removing water from a continuously flowing gas or liquid stream.
