Silica gel desiccant is a high-performance adsorption material and the most widely used desiccant product on the market. Its primary component is amorphous silicon dioxide, with the chemical formula mSiO₂·nH₂O. It features a porous, interlocking structure, providing a large specific surface area and high adsorption activity. This product complies with the Chinese Chemical Industry Standard HG/T2765-2005 and is registered with the U.S. FDA, making it the only desiccant approved for direct contact with food and pharmaceuticals.
Silica gel desiccant offers excellent moisture absorption, effectively controlling environmental humidity and preventing dampness and mold. It exhibits stable physical properties, maintaining structural integrity without softening or liquefying even when fully immersed in water. The product is non-toxic, odorless, and non-corrosive, ensuring safety for both humans and the environment, and can be directly placed in contact with any item.
Due to its chemical inertness and stability, silica gel desiccant is widely used in pharmaceutical packaging, food packaging, moisture-proofing for electronic products, military supply storage, household daily necessities, and many other fields. It is an ideal, safe, and reliable humidity control solution.
