Al Silica gel is a colorless or light yellow transparent or translucent spherical particles with stable chemical properties. It is non-combustible and 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, making it suitable 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 Orange Color Change Desiccant Beads in 20kg or 500kg bags. High-quality silica gel for effective moisture control.
Blue silica gel is available in blue or light blue glassy particles. The product comes in two types: blue silica gel indicator and blue silica gel. It is known for its hygroscopicity process, changing from blue to purple, and finally 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 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. The color change from blue to red visually indicates the relative humidity of the environment. When used with ordinary silica gel or a drier, it shows the moisture absorption level and helps determine the relative humidity. This versatile product is widely used as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.
