What Can 4A Molecular Sieve Adsorb and What is the Application?

Our factory dispatched 60tons of 4A Molecular Sieve and shipped to Brazil on November 8, 2022.


What is 4A Molecular Sieve?

Chemical Formula:  Na12[(AlO2)12(SiO2)12] • nH2O

Molecular sieve type 4A is an alkali aluminium silicate. This sodium form of Type- Crystal Structure has an effective pore opening of about 4 angstroms. The type 4A molecular sieve will adsorb most molecules with a kinetic diameter of fewer than 4 angstroms and exclude those larger.It can adsorbs water, methanol, ethanol, a small amount of hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene. It is one of the most widely used molecular sieves in gas treatment industry. We offer our 4A molecular sieve in bead and pellet form in the mesh size of 8×12 mesh and 4×8 mesh.


Application of 4A Molecular Sieve:

* Deep drying of gases and liquids such as air, natural gas, alkanes, refrigerants, etc.

* Preparation and purification of argon.

* Static drying of pharmaceutical packaging, electronic components and perishable substances.

* As a dehydrating agent in paints, fuels and coatings.
