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 by 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 original technological conditions and excellent adsorption performance as a new generation of environmental protection products.
This silica gel is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is ideal 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, perfect 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.
Chemical Formula: SiO2·nH2O + CoCl2
Characteristics: Narrow pore silica gel with interconnecting pores of 20-30 nanometers, effectively removing moisture through physical adsorption and capillary condensation.
Typical Applications: Compressed air dryers, gas drying, breathers, and packaged goods.
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.
Chemical Formula: mSiO2·nH2O
Specifications: Average pore diameter of 2.0-3.0nm, Surface Area of 650-800m2/g, Pore Volume of 0.35-0.45ml/g.
Applications: Primarily used for drying and moistureproof, as well as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.
