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 similar adsorption capacity at low humidity levels but outperforms in high humidity conditions by 6-10%. Additionally, it exhibits excellent thermal stability, making it suitable for variable temperature adsorption and separation processes.
Al Silica gel is primarily used for dehydrating natural gas by adsorbing and separating light hydrocarbons. 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 Cobalt-Free Silica Gel Variable-Pressure Adsorbents in 2.0kg or 500kg bags. Blue Silica Gel for effective moisture control.
Blue silica gel is composed of blue or light blue glassy particles. The product is categorized into blue silica gel indicator and blue silica gel. It exhibits hygroscopic properties, transitioning 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 replacement is needed. Blue silica gel can be used independently as a desiccant or in conjunction with Type A Silica Gel.
Blue silica gel is primarily utilized for absorbing moisture and preventing rust in instruments, gauges, and equipment within enclosed conditions. As it absorbs moisture, it changes color from blue to red, visually displaying the relative humidity of the surroundings. When used alongside ordinary silica gel or a drier, it helps gauge the moisture absorption capacity of the drier and assess the relative humidity of the environment. This versatile product is commonly employed as a silica gel drier for packaging precision instruments, leather goods, shoes, clothing, food items, medications, household appliances, and more.

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 made 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. The product retains its original technological conditions and offers excellent adsorption performance, establishing itself as a new generation of environmental protection products.
This silica gel is primarily used as a desiccant and to indicate desiccant saturation levels in sealed packaging. It is also suitable for monitoring relative humidity in precision instruments, general packaging, and instruments vulnerable to moisture.
