4A Molecular Sieve

4A Molecular Sieve is a kind of sodium metal aluminon-silicate, the sodium form of the type A crystal structure. The pore size of 4A molecular sieves is 4 angstrom and the limit of adsorb molecular diameters is 4 A. The approximate chemical formula is Na₁₂[(AlO₂)₁₂(SiO₂)₁₂]•XH₂O.

A variety of applications including:

Deep drying natural gas, oil field gas, saturated alkanes, refrigerants, organic solvents and other gases or liquids.
Static drying pharmaceutical packaging, electronic components and perishable chemicals.
Dehydrating agent for paint industry or dye industry.
