Silica gel desiccant is a kind of highly active adsorbent material, which is the most commonly used desiccant. It belongs to amorphous substance, its chemical molecular formula is mSiO2.nH2O. it is insoluble in water and any solvent, non-toxic, tasteless, chemically stable, and is a very safe, physical adsorption type desiccant, which can absorb and lock moisture through its own internal microporous structure (moisture absorption rate can reach 30%), and does not damp decompose after absorbing moisture.
