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 is a new generation of environmental protection products. It is based on blue gum color-changing silica gel but uses non-toxic compound dyes to eliminate pollution caused by dyes and discoloration agents.
This silica gel is ideal for use as a desiccant and to indicate desiccant saturation levels in sealed packaging. It is suitable for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.

Blue silica gel is an excellent primary desiccant that can also be 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 they adsorb moisture.
SiO2·nH2O + CoCl2
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.
mSiO2·nH2O
Mainly used for drying and moistureproof, as well as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
