Audited Supplier Type A silica gel is a transparent or translucent particle with a chemical formula mSiO2·nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions. This silica gel has high mechanical strength, good wear resistance, an average pore diameter of 2.0-3.0nm, surface area of 650-800m2/g, and pore volume of 0.35-0.45ml/g.
It is primarily used for drying and moistureproof purposes but can also serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.

Properties:
Al Silica gel is colorless or light yellow transparent or translucent spherical particles with a chemical formula mSiO2.nAl2O3.xH2O. It has stable chemical properties, is non-combustible, insoluble in any solvent except strong base and hydrofluoric acid. Compared with silica gel with fine holes, it has similar adsorption capacity at low humidity (e.g., RH=10%, RH=20%), but 6-10% higher adsorption capacity at high humidity (e.g., RH=80%, RH=90%). Its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it suitable for variable temperature adsorption and separation.
Application:
Mainly used for the adsorption and separation of light hydrocarbons by dehydration of natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and gas separation.

Silica Gel Desiccant Beads: Available in 2.0kg or 500kg bags, our blue silica gel beads from Lianyungang Chemsize International Trading Co., Ltd. are high-quality, odorless, and eco-friendly. Perfect for electronics and storage.
Blue silica gel is a type of desiccant that comes in blue or light blue glassy particles. It can indicate the humidity of the environment by changing color from blue to purple and finally to light pink. This product is available as blue silica gel indicator and blue silica gel. It can be used alone as a 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. 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 judge 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.

Properties: 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 varying adsorption residence times for different substance components, it enables the separation and purification of mixed components effectively.
Application: 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.
