4A molecular sieve
Our 4A molecular sieve products are alkali metal aluminosilicates in the spherical form. They are the sodium form of the Type-A crystal structure with an effective pore opening of 4 Angstroms. Our 4A molecular sieve will adsorb molecules such as oxygen, nitrogen, carbon dioxide, and straight chain hydrocarbons. We offer our 4A molecular sieve in bead and pellet form in the mesh sizes specified below. For all 4A molecular sieve types, aromatics and branched chain hydrocarbons will not be adsorbed.
Molecular sieve is also known as a zeolite. A zeolite is a conformation of hydrated aluminosilicates of sodium, potassium, calcium, or other cations. Zeolites can be dehydrated and rehydrated, making them useful in drying applications. These materials can also be used for cation exchange and as sieves on a molecular level. The molecular formula of a zeolite, namely the cations found in the molecules, determines the size of its pore openings.
