Blue Crystal Silica Gel is a type of desiccant that is commonly used for moisture absorption in various applications. It is a silica-based material with a blue color that changes to pink when it absorbs moisture. The blue color indicates that the silica gel is dry, while the pink color indicates that it has become saturated with moisture and needs to be replaced or regenerated. Blue Crystal Silica Gel is often used in packaging to protect goods and products from moisture damage during storage and transportation. It is also used in industrial applications such as drying and preserving flowers, electronics, and leather goods.
