Discover our Non-Toxic Cobalt-Free Blue Silica Gel Beads for water absorption. Available in bags of 200kg or 500kg. Perfect for moisture control!
Blue silica gel consists of blue or light blue glassy particles. The product is available as blue silica gel indicator and blue silica gel. It exhibits hygroscopicity, changing from blue to purple and eventually to light pink as it absorbs moisture. This color change indicates the humidity level and the need for replacement. Blue silica gel can be used independently as a desiccant or in conjunction with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed conditions. As it absorbs moisture, it changes color from blue to red, visually indicating the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps determine the drier's moisture absorption capacity and assess the relative humidity of the surroundings. This versatile product is commonly employed as a silica gel drier for packaging precision instruments, leather goods, shoes, clothing, food items, medications, and household appliances.

Size: 1-3mm, 2-4mm, 3-5mm. Packaging: 25kg bags. Cobalt-free color-changing silica gel beads for water absorption.
The European Union classified cobalt chloride as a Class II carcinogen in 1998, leading to the ban of blue gum containing cobalt chloride in Europe and the United States. To address market demands, cobalt-free environmental discoloration silica gel was developed.
This product, derived from blue gum color-changing silica gel, is now replaced with orange color-changing silica gel. It is made from fine porous silica gel infused with an inorganic salt mixture and utilizes non-toxic compound dyes, effectively eliminating environmental pollution caused by dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, it has become a new generation of environmentally friendly products.
This silica gel is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is ideal for maintaining the relative humidity of space medium in precision instruments, as well as protecting general packaging and instruments from moisture.
