Silica Gel White is a non-indicating, amorphous form of silicon dioxide (SiO₂) used primarily as a desiccant to control humidity and prevent moisture damage in a wide range of applications. Unlike blue silica gel, it does not change color when saturated, making it ideal for use where visual indicators are not required. It is chemically inert, odorless, and capable of adsorbing up to 40% of its weight in water vapor. Packaged in 25kg bags or drums, Silica Gel White is used across industries for packaging, preservation, drying, and moisture regulation.
