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 based on blue gum color-changing silica gel, with orange color-changing silica gel made from fine porous silica gel infused with an inorganic salt mixture. It utilizes new non-toxic compound dyes to eliminate pollution caused by dyes and discoloration agents, making it an environmentally friendly option with excellent adsorption performance.
This product is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is suitable for maintaining the relative humidity of space medium in precision instruments, as well as protecting general packaging and instruments from moisture.

Blue silica gel is an ideal primary desiccant that can be used alone or blended with other desiccants for applications requiring visual control of moisture. 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. The chemical formula is SiO2·nH2O + CoCl2. Known for its narrow pore structure with diameters of 20-30 nanometers, blue silica gel effectively removes moisture through physical adsorption and capillary condensation, best used at room temperature and high relative humidity.
Type A silica gel is a transparent or translucent particle with the chemical formula mSiO2·nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions, with high mechanical strength and good wear resistance. With an average pore diameter of 2.0-3.0nm, surface area of 650-800m2/g, and pore volume of 0.35-0.45ml/g, Type A silica gel is primarily used for drying and moistureproof applications, as well as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
