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, 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.
Application: 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 base and hydrofluoric acid. Compared to silica gel with fine holes, Al Silica gel has similar adsorption capacity at low humidity levels (e.g., RH=10%, RH=20%), but 6-10% higher adsorption capacity at high humidity levels (e.g., RH=80%, RH=90%). Additionally, it has a thermal stability of 350ºC, which 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 dehydrating natural gas by adsorbing and separating light hydrocarbons. 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.

Aluminium-Based Blue Silica Gel Desiccant for Moisture Adsorption in 2.0kg or 500kg bags by Lianyungang Chemsize International Trading Co., Ltd.
Blue silica gel consists of blue or light blue glassy particles. The product is available as blue silica gel indicator and blue silica gel. It is known for its hygroscopicity process, changing from blue to purple, and finally to light pink as it absorbs moisture. This color change indicates the humidity level and the need for replacement. Blue silica gel can be used alone as a desiccant 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. When used with ordinary silica gel or a drier, it helps determine the extent of moisture absorption and assess the relative humidity of the surroundings. This product is widely used as a silica gel drier for packaging precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Aluminium-Based Silica Gel Desiccant for Moisture Adsorption in sizes of 1-3mm, 2-4mm, and 3-5mm. Cobalt-free color-changing silica gel packed in 25kg bags.
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.
This silica gel is primarily used as a desiccant and to indicate 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.
