Discover our Sio2 Silica Gel Balls Cobalt-Free in 2.0kg or 500kg bags. These blue silica gel beads are perfect for moisture absorption and storage needs.
Blue silica gel consists of blue or light blue glassy particles. It is available as blue silica gel indicator and blue silica gel. The color changes from blue to purple to light pink as it absorbs moisture, indicating the humidity level and the need for replacement. It can be used as a standalone desiccant 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. The color change from blue to red visually indicates the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps determine the moisture absorption level and relative humidity. It is commonly used as a desiccant for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Sio2 Silica Gel Balls Cobalt-Free in sizes 1-3mm, 2-4mm, and 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, leading to the ban of blue gum containing cobalt chloride in Europe and the United States. To address market demands, cobalt-free environmental discoloration silica gel was developed.
This product, derived from blue gum color-changing silica gel, is made from fine porous silica gel infused with an inorganic salt mixture to create orange color-changing silica gel. It utilizes new non-toxic compound dyes, effectively eliminating environmental pollution caused by dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, it has become a new generation of environmentally friendly products.
Primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging, this product is ideal for maintaining the relative humidity of space mediums in precision instruments, as well as protecting general packaging and instruments from moisture.
