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.

Properties:
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 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 silica gel with fine holes, making it suitable for variable temperature adsorption and separation.
Application:
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 bags of 200kg or 500kg for effective moisture control. Ideal for industrial use, these transparent Type A Silica Gel Balls are a top-grade solution from Lianyungang Chemsize International Trading Co., Ltd.
Blue silica gel is composed 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 environment. It can also be used with ordinary silica gel or drier to determine the moisture absorption level and relative humidity of the surroundings. This versatile product is commonly used as a desiccant for packing precision instruments, leather goods, shoes, clothes, food items, medicines, and household appliances.
