4A Molecular Sieve
Pore diameter: 4 angstroms.
CAS No.: 1318-02-1.
Apperance: Sphere & Pellet.
National standard: HG/T 2524-2010.
Formula: Na₂O. Al₂O₃. 2SiO₂. 4.5H₂O.
Description：
4A Molecular Sieve is one of the most widely used molecular sieve in industry. It will capture molecules with a kinetic diameter smaller than 4 angstroms, while rejecting those with a larger diameter. It’s used to remove moisture from liquids and gases. It has reliable adsorption speed, higher resistance quality and stronger adsoprtion.

| Description： 4A Molecular Sieve is an alkali metal aluminosilicate with an effective of pore opening of 4 angsroms. It is the sodium forms of type A crystal structure. It is primarily for removing moisture from liquefied and gaseous materials. As a static desiccant in household refrigeration systems, pharmaceutical packaging, automotive air conditioning, electronic components, and mutated chemicals, or as a dehydrator in coating and plastic systems. It can also be used in industry to dry saturated hydrocarbons and adsorb methanol, ethanol, hydrogen sulfide, carbon dioxide, etc. |
