Type A silica gel is a transparent or translucent particle with a chemical formula mSiO2.nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid, and strong caustic soda solutions. This silica gel offers high mechanical strength and good wear resistance.
Primarily used for drying and moistureproof, Type A silica gel 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 base and hydrofluoric acid. Compared to silica gel with fine holes, it has similar adsorption capacity at low humidity (e.g., RH=10%, RH=20%), but 6-10% higher adsorption capacity at high humidity (e.g., RH=80%, RH=90%). Its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it suitable for variable temperature adsorption and separation.
Al Silica gel is primarily used for the adsorption and separation of light hydrocarbons by dehydrating natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and gas separation.

Blue silica gel consists of blue or light blue glassy particles. It can change color from blue to purple and finally to light pink as it absorbs moisture, indicating the humidity level of the environment. This desiccant can be used alone or in combination with Type A Silica Gel.
Blue silica gel is ideal 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 showing the relative humidity of the environment. It can be used with ordinary silica gel or drier to determine moisture absorption levels and relative humidity. This versatile product is commonly used as a desiccant for precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Experience color-changing silica gel balls from Lianyungang Chemsize in sizes of 1-3mm, 2-4mm, and 3-5mm. Cobalt-free and packed in 25kg bags.
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 superior adsorption performance and maintaining original technological conditions.
The cobalt-free environmental discoloration 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, general packaging, and instruments vulnerable to moisture.
