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 exhibits high mechanical strength and good wear resistance.
It is primarily used for drying and moistureproof purposes. Additionally, it can serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.

Al Silica gel is a colorless or light yellow transparent or translucent spherical particles with stable chemical properties. It is non-combustible, insoluble in most solvents except strong bases 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 offers 6-10% higher adsorption capacity at high humidity levels (e.g., RH=80%, RH=90%). Additionally, it has a thermal stability of over 350ºC, making it suitable 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.

Discover our Transparent Type A Silica Gel Beads in 2.0kg or 500kg bags. Ideal for moisture control in various applications. From 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 exhibits hygroscopic properties, changing from blue to purple and eventually 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 independently as a desiccant or in conjunction with Type A Silica Gel.
Primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed environments. The color change from blue to red visually indicates the relative humidity of the surroundings. When combined with ordinary silica gel or a drier, it helps determine the moisture absorption level and relative humidity. Blue silica gel is widely employed as a desiccant for packaging precision instruments, leather goods, shoes, clothing, food items, medications, and household appliances.

Size: 1-3mm, 2-4mm, 3-5mm. Packaging: 25kg bags. Cobalt-free color-changing silica gel beads by Lianyungang Chemsize International Trading Co., Ltd.
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 environmental pollution caused by dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, it has become a new generation of environmentally friendly products.
This product is primarily used as a desiccant and to indicate desiccant saturation levels in sealed packaging. It is suitable for maintaining the relative humidity of the space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
