Frequently Asked Questions

What are molecular sieves used for?

Molecular sieves are crystalline aluminosilicates used for drying gases and liquids, removing impurities, and separating molecules based on size. Common applications include insulating glass, PSA systems, and petrochemical refining.

What is the difference between 3A, 4A, 5A, and 13X molecular sieves?

The numbers refer to pore size in angstroms: 3A (3Å) for water removal in ethanol, 4A (4Å) for general drying, 5A (5Å) for normal paraffin separation, and 13X (10Å) for large molecule adsorption like CO₂ and NH₃.

Can I get samples before placing an order?

Yes, we offer sample shipments upon request. Please contact us through the official website to request product samples for evaluation.
