The European Union classified cobalt chloride as a Class II carcinogen in 1998. Blue gum containing cobalt chloride has been banned 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 available in an orange variant. It is made from fine porous silica gel infused with an inorganic salt mixture and utilizes new non-toxic compound dyes. This innovation eliminates environmental pollution caused by dyes and discoloration agents, offering superior adsorption performance.
Our cobalt-free silica gel is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is ideal for maintaining optimal humidity levels in precision instruments, general packaging, and moisture-sensitive equipment.

Blue silica gel is an ideal primary desiccant that can be used alone or blended with other desiccants for applications requiring visual moisture control. Chemsize silica gel beads are saturated with a moisture indicating solution, turning deep blue when dry and changing to purple and pink as moisture is adsorbed.
Type A silica gel is a transparent or translucent particle with high mechanical strength and good wear resistance. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions.
Mainly used for drying, moistureproofing, catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
