Product Description
5A Molecular Sieve
5A Molecular Sieve, has an effective pore opening of 5 angstroms(0.5nm).
It will adsorb molecules with a kinetic diameter of less than 5 angstrom and exclude those larger.
It has high select adsorption and fast adsorption speed.
Chemical Molecular Formula: 0.7CaO·0.3Na2O·Al2O3·2SiO2·4.5H2O. (SiO2 : Al2O3 ≈2).
