3A Molecular sieve is made by aluminosilicate. Because of its special crystal structure and 3A length mesh, it can totally adsorb the substance whose diameter is smaller than 3A. It is generally used as desiccant in chemical、medical、petrochemical、insulating glass and so on.
Chemical Formula:2/3K2O*1/3Na2O* Al2O3*2SiO2*9/2H2O
Si/Al ratio:SiO2/ Al2O3≈2
