Type A silica gel is a transparent or translucent particle with the 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, good wear resistance, an average pore diameter of 2.0-3.0nm, surface area of 650-800m2/g, and pore volume of 0.35-0.45ml/g.
It is primarily used for drying and moistureproof purposes but can also 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 any solvent except strong bases and hydrofluoric acid. Compared to silica gel with fine holes, Al Silica gel has a higher adsorption capacity for high humidity levels (RH=80%, RH=90%) and superior thermal stability (350ºC).
Al Silica gel is ideal for the adsorption and separation of light hydrocarbons in natural gas dehydration. It can also be used as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and gas separation.

High-Density Silica Gel Beads for Moisture Adsorption in 20kg or 500kg bags. Blue Silica Gel by Lianyungang Chemsize International Trading Co., Ltd.
Blue silica gel consists of blue or light blue glassy particles, categorized into blue silica gel indicator and blue silica gel. It exhibits hygroscopicity, transitioning 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 moisture absorption and rust prevention in enclosed environments for instruments, gauges, and equipment. The color change from blue to red visually signifies 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. Widely utilized in packaging precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household appliances.
