 [ Products Description ]
The pore size of 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, does not dsorb any larger molecular than 4A, and often used as desiccant in industrials.
Formual: Na2O, Al2O3, 2.0SiO2, 4.5H2O
