Product Description

4a Molecular Sieve Desiccant For Generation And Purification Of Argon
Products Introduction
The pore size for Molecular Sieve 4A. The sodium based molecule is mainly used to adsorb water, methanol, ethanol, sulphureted hydrogen, carbon dioxide, ethylene, propylene. Type 4a available in beads and pellets which all plays a major role to replace sodium tripolyphosphate as the detergent auxiliary that makes environment free from pollution. It does not adsorb any larger molecule than its pore size.

Molecular FormulaNa2O·Al2O3·2SiO2·9/2H2O
SiO2/ Al2O3≈ 2
Normal Pore Opening4 Angstroms (Å)
Regeneration temp. (°C)200-315
AdvantagesHigh Stability; High Strength; Large Water Absorption; Low Attrition; Deep Dehydration
