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 strona bese 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 exhibits 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 suitable 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.

Product Name: Cobalt-Free Blue Silica Gel Catalyst
Description: Premium grade blue silica gel beads for efficient moisture absorption. Ideal for humidity control and drying applications. Available in 2.0kg or 500kg bags.
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 hygroscopic nature, 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 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. The color change from blue to red visually indicates the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps determine the moisture absorption level and relative humidity. This versatile product is widely used as a desiccant for packing precision instruments, leather goods, shoes, clothing, food items, medicines, and household appliances.

Description: High-quality color-changing silica gel for moisture absorption, available in various sizes. Ideal for industrial use.
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 meet market demands, cobalt-free environmental discoloration silica gel was developed.
The product, based on blue gum color-changing silica gel, is orange and made from fine porous silica gel infused with an inorganic salt mixture. It utilizes new non-toxic compound dyes to eliminate pollution from dyes and discoloration agents, making it an environmentally friendly option with excellent adsorption performance.
It is primarily used as a desiccant and to indicate desiccant saturation levels in sealed packaging. It is also suitable for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments to prevent moisture damage.
