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 new non-toxic compound dyes. This innovation eliminates environmental pollution caused by dyes and discoloration agents, offering superior adsorption performance and maintaining original technological conditions.
Primarily used as a desiccant and indicator of desiccant saturation levels, this silica gel is ideal for sealing packaging, monitoring relative humidity in precision instruments, and 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 moisture control. Chemsize silica gel beads are saturated with a moisture indicating solution, turning deep blue when dry and changing color as they adsorb moisture. With a chemical formula of SiO2·nH2O + CoCl2, this narrow pore silica gel has a network of interconnecting pores with diameters of 20-30 nanometers, effectively trapping and holding moisture through physical adsorption and capillary condensation. It is best used at room temperature and high relative humidity, suitable for various applications such as compressed air dryers, gas drying, breathers, and packaged goods.
Type A silica gel is a transparent or translucent particle with a chemical formula of 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.
