Description
Silica Gel is a highly porous, granular form of silicon dioxide (SiO₂) widely used as a desiccant to control moisture and humidity. It is chemically inert, non-toxic, and available in different forms such as white silica gel, indicating (blue/orange) silica gel, and beads or crystals. Due to its strong adsorption capacity, Silica Gel is used in pharmaceuticals, electronics, food packaging, leather goods, and industrial applications to protect products from moisture damage.
