Molecular Sieve 3A is one kind of alkali metal alumino-silicate. Sometimes, it is also called 3A zeolite molecular sieve. The aperture of this molecular sieve is 3A. Therefore, It does not adsorb the objects whose molecular diameters are larger than 3Å. 3A molecular sieve's formula is 2/3K2O•1/3Na2O•Al2O3• 2 SiO2 • 9/2 H2O. 3A molecular sieve desiccant is the necessary desiccant in petroleum, chemical industry.

Application
1) Drying of unsaturated hydrocarbons(e.g.. ethylene,propylene,butadien)
2) Cracked Gas Drying
3) Drying of natural gas,if COS minimization is essential,or a minimum co-adsorption of hydrocarbons is required.
4) Drying of highly polar compounds,such as methanol and ethanol
5) Drying of liquid alcohol
6) Static,(non-regenerative) dehydration of insulating glass units,whether air filled or gas-filled.
