        Zeolite 4A

        CAS No.: 70955-01-0
        Molecular formula: 0.4K2O 0.6Na2O Al2O3 2.0SiO2 4.5H2O
        Packing: 40kg/Bag; 18MT can be loaded into 1x20’FCL
        Is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). XINTAO type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
        Widely used in detergents and used as ion-exchange beds in domestic, commercial water purification, softening, a soil treatment, and solar thermal collectors and for adsorption refrigeration, catalysts in the petrochemical industry, and use in laundry detergent, advanced reprocessing methods, general odor elimination for all animal odors, an additive in the production process of warm mix asphalt concrete and so on.
