About Molecular Sieves 3A

3A molecular seive refers to type A potassium salt sialic acids. A molecular sieve with 3A critical diameter can adsorb molecules. It is widely used for drying unsaturated hydrocarbon gases, such as butadiene (butylene), ethylene (propylene), and ethanol. It can also be used for polar liquids, such as ethanol. It is the preferred choice in the petroleum and chemical industries for deep drying, refinement, and polymerization.
