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 base and hydrofluoric acid. Compared to silica gel with fine holes, Al Silica Gel has a higher adsorption capacity for high humidity levels (such as RH=80%, RH=90%) and superior thermal stability (350ºC).
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, industrial desiccant liquid adsorbent, and gas separation agent.

Discover our Microspheres Silica Gel Moistureproof Balls in 20kg or 500kg bags. These Cobalt-Free Blue Silica Gel beads are efficient, quick-drying, and eco-friendly. Perfect for moisture absorption!
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 in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually indicating the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps determine the extent of moisture absorption and assesses the relative humidity of the surroundings. This product is commonly used as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Description: Cobalt-free color-changing silica gel beads for effective moisture absorption. Ideal for industrial and personal use.
The European Union classified cobalt chloride as a Class II carcinogen in 1998. Blue gum containing cobalt chloride has been banned in Europe and the United States. To address market demands, cobalt-free environmental discoloration silica gel was developed.
This product is based on blue gum color-changing silica gel. Orange color-changing silica gel is created from fine porous silica gel infused with an inorganic salt mixture. It utilizes new non-toxic compound dyes to eliminate pollution caused by dyes and discoloration agents, making it an environmentally friendly option. With its original technological conditions and excellent adsorption performance, it has become a new generation of environmental protection products.
This product is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is also suitable for monitoring the relative humidity of the space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
