Type A silica gel is a transparent or translucent particle with the chemical formula mSiO2.nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions. This silica gel exhibits high mechanical strength and good wear resistance.
It is primarily used for drying and moistureproof purposes. Additionally, it can serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.

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 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.

Discover our Cobalt-Free Silica Gel Desiccant Beads in bags of 200kg or 500kg. Made with Sio2>98%, these Blue Silica Gel beads are ideal for moisture absorption.
Blue silica gel consists of blue or light blue glassy particles. The product is available as blue silica gel indicator and blue silica gel. It is characterized by its hygroscopicity process, turning 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 a new desiccant 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 used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed conditions. As 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 shows the extent of moisture absorption and helps determine the relative humidity of the surroundings. This product is widely utilized as a silica gel drier for packaging precision instruments, leather goods, shoes, clothing, food items, medicines, and household appliances.

Cobalt-Free Silica Gel Desiccant Beads in sizes 1-3mm, 2-4mm, 3-5mm. Packed in 25kg bags. Color-changing silica gel by Lianyungang Chemsize International Trading Co., Ltd.
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.
Products with original technological conditions and excellent adsorption performance have become a new generation of environmental protection products.
This silica gel is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is suitable for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.
