Silica Gel Desiccant
Silica Gel is available in porous, granular, and amorphous form chemical reaction between Sulfuric acid and Sodium Silicate. The internal structure of Slilica 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 capilary condensation.
