Introduction:

Silica gel desiccant is a highly active adsorbent material and is the most commonly used desiccant. It is an amorphous substance with a chemical formula of mSiO2·nH2O, conforming to the Chinese chemical standard HG/T2765-2005. It is the only desiccant approved by the FDA for direct contact with food and pharmaceuticals. Silica gel desiccant has a strong moisture absorption capacity and excellent adsorption performance; even when fully immersed in water, it does not soften or liquefy. It is non-toxic, odorless, non-corrosive, and non-polluting, making it safe for direct contact with any items.
