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 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 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 bases and hydrofluoric acid. Compared to silica gel with fine holes, it has a similar adsorption capacity at low humidity levels (e.g., RH=10%, RH=20%), but a 6-10% higher adsorption capacity at high humidity levels (e.g., RH=80%, RH=90%). Additionally, its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it suitable for variable temperature adsorption and separation.
Al Silica Gel is primarily used for the adsorption and separation of light hydrocarbons by dehydrating natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and for gas separation.

Discover our Blue Silica Gel packets in 2.0kg or 500kg bags. Perfect for moisture control with our Microspheres Silica Gel Variable-Pressure Adsorbent.
Blue silica gel consists of blue or light blue glassy particles. It can change color from blue to purple 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 in enclosed conditions. Its 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 commonly used as a desiccant for packing precision instruments, leather goods, shoes, clothing, food items, medicines, and household appliances.
