4 A molecular Sieves

4A molecular sieve has a pore size of 4A or 4 angstrom. Any molecule larger than 4A will not be able to be adsorbed.  4 Angstroms are the sodium forms of the Type A crystal structure. It is mainly used to absorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene

The advantages of our high quality 4A mole sieve are consistent adsorption speed, and higher contamination resistance, stronger crushing increasing cyclic times which provide an extended product life. 4A Molecular Sieve is primarily for removing moisture from liquefied and gaseous materials.
