Discover our Blue Silica Gel Balls in 2.0kg or 500kg bags for effective moisture control. Ideal for industrial use, these desiccant balls ensure minimal loss on heating.
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 highly hygroscopic, changing from blue to purple and eventually to light pink as it absorbs moisture. This color change indicates the humidity level and the need for replacement. Blue silica gel can be used independently as a desiccant or in conjunction with Type A Silica Gel.
Primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed environments. The color change from blue to red visually indicates the relative humidity of the surroundings. When used with ordinary silica gel or a drier, it helps assess the moisture absorption level and relative humidity. Blue silica gel is commonly used as a desiccant for packing precision instruments, leather goods, shoes, clothing, food items, medications, and household appliances.

Product Name: Cobalt-Free Color-Changing Silica Gel Balls
Description: High-quality silica gel balls for moisture control, ideal for industrial use. Cobalt-free and color-changing for effective humidity management.
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 a new generation environmental protection solution based on blue gum color-changing silica gel. It is made from fine porous silica gel infused with an inorganic salt mixture to create orange color-changing silica gel. The use of non-toxic compound dyes eliminates pollution from traditional dyes and discoloration agents.
With its original technological conditions and excellent adsorption performance, this product offers a sustainable alternative for various applications.
This cobalt-free environmental discoloration silica gel is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is ideal for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.

Column chromatography silica gel is a white uniform powder with particles ranging in size. It is non-toxic and tasteless, composed mainly of silica. Known for its high purity, safety, and health benefits, it separates and purifies different substance components efficiently due to varying adsorption residence times.
Primarily used in refining petroleum products, removing aromatic substances, and separating and purifying active components in Chinese herbal medicine. It is also ideal for preparing high-purity substances.
