Al Silica Gel
Al Silica Gel
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, and insoluble in any solvent except strong base and hydrofluoric acid. Compared to 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%). It also has a thermal stability of over 350ºC, 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.

Discover our Blue Silica Gel in bags of 200kg or 500kg from Lianyungang Chemsize International Trading Co., Ltd. Ideal for moisture absorption.

Blue Silica Gel
Properties
Blue silica gel consists of blue or light blue glassy particles. The product is available as blue silica gel indicator and blue silica gel. It exhibits hygroscopicity, changing from blue to purple and eventually to light pink as it absorbs moisture. This color change indicates the humidity level and the need for replacement. Blue silica gel can be used alone as a desiccant or in conjunction with Type A Silica Gel.
Application
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed conditions. The color change from blue to red visually indicates the relative humidity of the environment. When used with ordinary silica gel or a drier, it helps determine the moisture absorption level and relative humidity. This versatile product is commonly used as a desiccant for precision instruments, leather goods, shoes, clothing, food items, medications, and household appliances.
