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 ideal for the adsorption and separation of light hydrocarbons in natural gas dehydration. It can also be used as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and gas separation.

Discover our Silica Gel Desiccant for moisture control in 2.0kg or 500kg bags. Ideal for packaging and humidity control. High-quality solution from Lianyungang Chemsize International Trading Co., Ltd.
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 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. When it absorbs moisture, it changes color from blue to red, visually indicating the relative humidity of the environment. It can be used with ordinary silica gel or a drier to assess moisture absorption levels and judge relative humidity. This versatile product is commonly used as a desiccant for precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Discover our Cobalt-free Color-changing Silica Gel in sizes of 1-3mm, 2-4mm, and 3-5mm. Packed in 25kg bags for effective moisture control.
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 from dyes and discoloration agents, making it an environmentally friendly product with excellent adsorption performance.
It is primarily used as a desiccant and to indicate desiccant saturation levels in sealed packaging. It is also suitable for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
