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. Orange color-changing silica gel is 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.
The cobalt-free environmental discoloration silica gel 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, general packaging, and instruments vulnerable to 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 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 operates efficiently at room temperature and high relative humidity, making it suitable for various applications including 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, but soluble in hydrofluoric acid and strong caustic soda solutions. This silica gel boasts high mechanical strength, good wear resistance, an average pore diameter of 2.0-3.0nm, surface area of 650-800m2/g, and pore volume of 0.35-0.45ml/g. Primarily used for drying and moistureproofing, it can also serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
