ShangHai DSKS Molecular Sieve CO.,Ltd


Molecular Formula: 0.67K2O·0.33Na2O·Al2O3·2SiO2·4.5H2O


Molecular sieves 3A

Molecular sieve 3A is an alkali metal alumino silicate, it is the potassium form of the type A crystal structure.

Molecular sieve 3A has an effective pore opening of about 4 angstroms, it adsorbs molecular with effective diameters smaller than approximately 3 angstroms.But excludes molecules such as unsaturated hydrocarbons.

Recommended Application:

·Drying of unsaturated hydrocarbons (e.g.ethylene,butadien)

·Cracked gas drying.

·Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of     hydrocarbons is required..

·Drying of highly polar compounds,such as methanol and ethanol.

·Static,(non-regenerative)dehydration of insulating glass uints, whether air filled or gas-filled.

·Dehydration of refrigerant.



·55 gallon (150kg )air-tight iron drum.

·25 kg/carton,and each carton has inner PE bag.

·Other packing according to your requirement.


Instruction: Prevent molecular sieve from exposing directly to the air.

Warning: Molecular sieve adsorption activity is an exothermic reaction,any contact to human body is dangerous.
