What Is a Silica Gel?
Silica gel is a versatile and efficacious desiccant used to absorb and hold moisture from its local environment. It is a solid particulate material, but its name derives from the gelation process used to manufacture it. It consists of tiny, nano-porous beads or crystals of silicon dioxide.
The key characteristic of silica gel is its extreme ability to adsorb water vapor and virtually any aqueous substance. Its extraordinarily fine porosity results in a massive functional surface area, allowing it to trap and hold moisture molecules on its extensive surface. This essentially isolates the water from surrounding surfaces, preventing damage or degradation in products and materials thus protected. Its moisture-adsorbing capabilities make it a valuable tool for controlling humidity and protecting against the chemical and biological effects of moisture in most product and industrial contexts.
