What is Molecular Sieve?
Molecular sieve is a synthetic desiccant that has a very strong
affinity for moisture molecules. As part of the manufacturing process,
the pore size on the molecular sieve particles can be controlled.
The most commonly used pore size is 4 angstroms (4A) although 3
angstroms (3A), 5 angstroms (5A) and 10 angstroms (13X) are available.
Because the pore size is controllable, molecular sieve can be used
for picking up specific gases as well as moisture. Molecular sieve
can hold moisture to temperatures well past 450°F (230°C). Because
of its high affinity for moisture, molecular sieve is able to bring
the relative humidity in packages down as low as 10% RH.
