Learn Zeolite Molecular Sieve 4A
Molecular Sieve 4A is a highly effective desiccant and adsorbent belonging to the alkali aluminosilicate family. Its sodium form boasts a well-defined type A crystal structure with an effective pore opening of approximately 4 angstroms (0.4 nm). This precise selectivity allows it to selectively adsorb molecules with smaller kinetic diameters, making it ideal for applications requiring high water and CO2 removal.
