Al Silica gel is a colorless or light yellow transparent or translucent spherical particles with stable chemical properties. It is non-combustible, insoluble in any solvent except strong base and hydrofluoric acid. Compared to silica gel with fine holes, Al Silica gel has a 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 the adsorption and separation of light hydrocarbons in natural gas dehydration. 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 Aluminium-Based Silica Gel Desiccant for Water Absorption in 2.0kg or 500kg bags. Blue Silica Gel beads for effective moisture control.
Blue silica gel is composed of blue or light blue glassy particles. It can indicate the humidity of the environment by changing color from blue to purple and finally to light pink. 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 in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually indicating the relative humidity of the environment. It is commonly used in packaging precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Discover our Cobalt-Free Color-Changing Silica Gel in sizes of 1-3mm, 2-4mm, and 3-5mm. Packed in 25kg bags for your convenience. Perfect for water absorption needs.
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 a new generation environmental protection solution based on blue gum color-changing silica gel. It is made from fine porous silica gel infused with an inorganic salt mixture to create orange color-changing silica gel. The use of non-toxic compound dyes eliminates pollution from traditional dyes and discoloration agents.
With its original technological conditions and excellent adsorption performance, this product sets a new standard for environmental protection products.
This 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, as well as protecting general packaging and instruments from moisture.

Coarse pore microsphere silica gel consists of milky white particles with the main composition of SiO2·nH2O. It is insoluble in water and inorganic acids but soluble in hydrofluoric acid and strong caustic soda solutions. The pore volume ranges from 0.80-1.2 ml/g, pore diameter from 8-12nm, and surface area from 350-460m2/g.
This silica gel is primarily used as a catalyst and catalyst carrier for essential petrochemical products like phthalic anhydride, aniline, maleic anhydride, triacrylonitrile, and more. It is also widely utilized in refining petroleum products, selectively adsorbing and separating organic gases and liquid components. Additionally, it serves as an ion exchanger to eliminate harmful elements from water, aids in dry storage of materials, equipment, and other articles, and facilitates high purity gas dehydrating refining.
