ProductDescription

4A molecular Sieve Adsorbent

4A Molecular Sieve, is an alkali alumina silicate. It is the sodium form of the type A crystal structure. It has an effective pore opening of about 4 angstroms(0.4nm). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.
4A Molecular Sieve, the pore size distribution is very uniform, has very good adsorption properties and good oil adhesion, and has a certain buffer alkalinity effect. It is non-toxic, safe and reliable to human body, and has no adverse effects on ecosystem.
