High Purity Silica Gel Beads in 2kg or 500kg bags. Blue Silica Gel for desiccant use. Available from Lianyungang Chemsize International Trading Co., Ltd.
Blue silica gel consists of blue or light blue glassy particles. It can change color from blue to purple to light pink as it absorbs moisture, indicating the humidity level of the environment and the need for replacement. It 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 widely utilized as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

High Purity Silica Gel Beads in 1-3mm, 2-4mm, 3-5mm sizes. Cobalt-free color-changing silica gel. Packaged in 25kg bags.
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 properties and offers excellent adsorption performance, making it 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 relative humidity in precision instruments, general packaging, and instruments vulnerable to moisture.

Column chromatography silica gel is a white uniform powder particles, non-toxic, and tasteless. The main component is silica, known for its high purity, safety, and health benefits. Due to its varying adsorption residence times for different substance components, it effectively separates and purifies mixed components.
Primarily used for refining petroleum products by removing aromatic substances or for separating and purifying the active components of Chinese herbal medicine. It is also ideal for the preparation of high-purity substances.
