Product Details ofChemical Zeolite 4A Molecular Sieve Adsorbent

 

Molecular sieves are crystalline metal alumino silicates having a three dimensional interconnecting network of silica and alumina  tetrahedra. Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively  adsorb molecules of a specific size.
