Silica gel is a desiccant known for its great moisture-adsorbing capabilities. Silica gel consists of silicon dioxide and is shaped as small, porous beads. Silica gel is available in different types and sizes, making it a versatile desiccant capable of application across a wide range of industries. Its primary role is to adsorb moisture, preventing it from damaging the surrounding environment or products. Unlike regular silica gel (known as bulk, or non-indicating silica gel), indicating silica gel is enhanced with color-changing indicators. These indicators, typically either cobalt chloride or methyl violet, change color as the silica gel saturates with moisture. This visible change serves as an effective moisture detection mechanism, providing a clear visual indication of when the silica gel needs to be replaced or recharged.
