Type 4A Molecular Sieve is the preferred adsorbent
for static dehydration in a closed gas or liquid system. It is used
as a static desiccant in household refrigerating systems, packaging
of drugs, electronic components, perishable chemicals and as a
water scavenger in paint and plastic systems. Also used
commercially in drying saturated hydrocarbon streams. The sodium
form of Zeolite.
Type 4A Molecular Sieve is typically used in regenerable drying
systems to remove water vapor or contaminants that have a smaller
critical diameter than four angstroms.
