Discover our Color-Changing Silica Gel Beads for effective moisture control. Available in bags of 200g or 500g. Perfect for maintaining freshness and reducing humidity.
Blue silica gel is composed of blue or light blue glassy particles. It can change color from blue to purple and finally to light pink as it absorbs moisture, indicating the humidity level of the environment. This product can be used as a desiccant on its own 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. 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 assess the relative humidity of the surroundings. This product is commonly used as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Size: 1-3mm, 2-4mm, 3-5mm. Packaging: 25kg bags. Cobalt-free color-changing silica gel beads for moisture control.
The European Union classified cobalt chloride as a Class II carcinogen in 1998, leading to its ban 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 but uses non-toxic compound dyes to eliminate pollution caused by traditional dyes and discoloration agents. It maintains excellent adsorption performance while being environmentally friendly.
Primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging, this silica gel is ideal for maintaining the relative humidity of space medium in precision instruments and protecting general packaging and instruments from 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 different adsorption residence times for various substance components, it can effectively separate and purify mixed components.
It is primarily used for refining petroleum products, removing aromatic substances, and separating and purifying the active components of Chinese herbal medicine. It is also ideal for preparing high-purity substances.
