4A molecular sieve is a synthetic crystalline aluminosilicate with a regular micropore structure which is the sodium form of the Type A structure. It has a pore size of 4 angstrom.
4A molecular sieve has the features of excellent adsorption speed, high chemical resistance, and stronger adsorption. It is commonly used for drying of organic liquids (solvents, oils, gasoline and other saturated hydrocarbons), air, liquid gases (propane, butane), as well as noble and other gases (H2, N2, He, Ar, etc.). It exhibits high water adsorption capacity at low partial pressures and at temperatures up to 100°C.
