Discover Blue to Pink Silica Gel by Lianyungang Chemsize. Available in 2.0kg or 500kg bags. Ideal for packaging needs.
Blue silica gel consists of blue or light blue glassy particles. It can indicate humidity levels by changing color from blue to purple and finally to light pink. This desiccant is ideal for absorbing moisture and 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 absorbing moisture, indicating the relative humidity of the environment. It is commonly used in packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Blue to Pink Silica Gel by Lianyungang Chemsize International Trading Co., Ltd. offers cobalt-free color-changing silica gel beads in sizes of 1-3mm, 2-4mm, and 3-5mm, packed 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 and new non-toxic compound dyes. This innovation eliminates environmental pollution caused by dyes and discoloration agents, offering excellent adsorption performance and maintaining technological conditions.
Primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. Ideal for maintaining the relative humidity of space medium in precision instruments, general packaging, and moisture protection for instruments.
