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 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, its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it ideal for variable temperature adsorption and separation applications.
Application:
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.

Discover our High-Density Silica Gel Beads for water absorption in convenient bags of 200kg or 500kg. The blue silica gel from Lianyungang Chemsize International Trading Co., Ltd. is a top choice for efficient moisture control.
Blue silica gel consists of blue or light blue glassy particles. The product is available in two types: blue silica gel indicator and blue silica gel. It exhibits hygroscopic properties, changing from blue to purple and eventually to light pink as it absorbs moisture. This color change indicates the humidity level of the environment and signals when it needs replacement. Blue silica gel can be used as a standalone desiccant or in conjunction with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment within enclosed conditions. As it absorbs moisture, it transitions from blue to red, visually indicating the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps assess the moisture absorption capacity of the drier and determine the relative humidity of the surroundings. This versatile product is commonly employed as a silica gel drier for packaging precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.
