Al Silica gel is a colorless or light yellow transparent or translucent spherical particles with stable chemical properties. It is non-combustible, insoluble in most solvents except strong bases 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 350ºC, which is more than 150ºC higher than silica gel with fine holes, making it ideal 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 Blue Type A Silica Gel in 2.0kg or 500kg bags. Perfect for moisture absorption, this transparent variable-pressure gel is a top choice.
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 conjunction 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 displaying the relative humidity of the surroundings. When used with ordinary silica gel or a drier, it helps determine the extent of moisture absorption and assesses the relative humidity of the environment. This versatile product is widely used as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.
