Discover our Type B Silica Gel Catalyst Carrier Material Pack in 200kg or 500kg bags. The blue silica gel is a top-quality desiccant solution for industrial use.
Blue silica gel consists of blue or light blue glassy particles. It can change color from blue to purple 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. It changes color from blue to red as it absorbs moisture, providing a visual indication of the relative humidity. When used with ordinary silica gel or a drier, it helps determine the moisture absorption level and relative humidity of the environment. This versatile product is commonly used as a desiccant for precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Discover our Cobalt-Free Color-Changing Silica Gel in various sizes. Ideal for packaging in 25kg bags. Perfect for industrial use.
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, Lianyungang Chemsize International Trading Co., Ltd. developed cobalt-free environmental discoloration silica gel.
This innovative product, derived from blue gum color-changing silica gel, is now available as orange color-changing silica gel. It is made from fine porous silica gel infused with an inorganic salt mixture and utilizes new non-toxic compound dyes. By eliminating the environmental pollution caused by dyes and discoloration agents, this product offers superior adsorption performance and environmental protection benefits.
The 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.

Column chromatography silica gel is a white uniform powder consisting of non-toxic and tasteless particles. The main component is silica, known for its high purity, safety, and health benefits. Due to its varying adsorption residence times for different substance components, it effectively separates and purifies mixed components.
Primarily used for refining petroleum products by removing aromatic substances or for separating and purifying the active components of Chinese herbal medicine. It is also ideal for preparing high-purity substances.
