5A Molecular Sieve
5A Molecular Sieve
5A Molecular Sieve is an alkali alumino silicate; 5A Molecular Sieve is the calcium form of the Type A crystal structure. 5A Molecular Sieve has an effective pore opening of 5 angstroms (0.5 nm). 5A Molecular sieve will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.
5A molecular sieve material is especially suitable for PSA adsorber applications where it may be used for the separation of normal- and iso-paraffins (C4 to C6 species), in PSA hydrogen purification and in oxygen concentrators.
