Type A silica gel is a transparent or translucent particle with a chemical molecular formula mSiO2.nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions. This silica gel exhibits high mechanical strength and good wear resistance.
It is primarily used for drying and moistureproof purposes but can also serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.

Al Silica gel is colorless or light yellow transparent or translucent spherical particles with a chemical formula mSiO2.nAl2O3.xH2O. It has stable chemical properties, is non-combustible, and insoluble in any solvent except strong bases and hydrofluoric acid. Compared to silica gel with fine holes, it has similar adsorption capacity at low humidity levels (e.g., RH=10%, RH=20%), but shows 6-10% higher adsorption capacity at high humidity levels (e.g., RH=80%, RH=90%). Additionally, its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it ideal for variable temperature adsorption and separation applications.
Al Silica Gel is primarily used for the adsorption and separation of light hydrocarbons through the dehydration of natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, as well as an industrial desiccant, liquid adsorbent, and gas separation agent.

Blue silica gel consists of blue or light blue glassy particles. It can change color from blue to purple to light pink as it absorbs moisture, indicating the humidity level of the environment. It can be used as a desiccant on its own or in combination with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually indicating the relative humidity of the environment. It can be used with ordinary silica gel or a drier to determine the moisture absorption level and relative humidity in various environments. This product is commonly used as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Packaging: Bags of 25kg
Description: High-quality color-changing silica gel beads for effective moisture absorption. Perfect for various applications.
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 and new non-toxic compound dyes. This innovation eliminates pollution from dyes and discoloration agents, offering original technological conditions and excellent adsorption performance.
Primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. Ideal for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
