Desiccant

A desiccant is a substance that absorbs moisture from its surroundings, helping to keep environments or items dry. Common examples include silica gel packets found in product packaging and certain clays or salts. They are used in packaging, storage containers, and electronic cases to prevent moisture buildup, which can cause damage like rust, mold, or degradation. Desiccants work by drawing water vapor into their porous structure or through chemical reactions, effectively reducing humidity and protecting sensitive items from moisture-related issues.
