Discover Ultra-Pure Sio2 Silica Gel Desiccant by Lianyungang Chemsize. Ideal for water absorption in 200kg or 500kg bags.
Blue silica gel is a type of desiccant that comes in blue or light blue glassy particles. It changes 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 alone or 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. It changes color from blue to red when it absorbs moisture, providing a visual indication of the relative humidity. When used with ordinary silica gel or a drier, it helps determine the extent of moisture absorption and assesses the relative humidity of the environment. It is commonly used as a desiccant for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Discover Cobalt-Free Color-Changing Silica Gel Beads in sizes of 1-3mm, 2-4mm, and 3-5mm. Packed in 25kg bags 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 now replaced with orange color-changing silica gel. It is made from fine porous silica gel infused with a mixture of inorganic salts and new non-toxic compound dyes. This innovation eliminates environmental pollution caused by dyes and discoloration agents, offering superior adsorption performance and maintaining original technological conditions.
Our cobalt-free 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, as well as protecting general packaging and instruments from moisture damage.
