Properties:
Al Silica gel is colorless or light yellow transparent or translucent spherical particles with chemical molecular formula mSiO2.nAl2O3.xH2O. It has stable chemical properties, is non-combustible, insoluble in any solvent except strong base and hydrofluoric acid. Compared with 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 that of silica gel with fine holes, making it suitable for variable temperature adsorption and separation.
Application:
It is mainly used for the adsorption and separation of light hydrocarbons by dehydration of natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and gas separation.

Discover our Blue Silica Gel in 2.0kg or 500kg bags from Lianyungang Chemsize. Ideal for moisture absorption in various applications.
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 product 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 kept in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually showing the relative humidity of the surroundings. When used with ordinary silica gel or a drier, it helps determine the moisture absorption level and relative humidity of the environment. This versatile product is commonly used as a desiccant for packing 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 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.
The product, derived from blue gum 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 indicator of 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.
