In addition to prepackaged desiccants from 0.25 gram packets up to 5 pound cans,
IMPAK provides bulk desiccant for industrial and commercial applications.
We have 3 and 5 pound cans of unique silica gel products like FNG and narrow pore,
as well as standard 5 pound cans of indicating silica gel and 5 pound cans of
non-indicating silica gel. Both of the previous items are listed below in case
quantities for your convenience.
Bulk molecular sieve, indicating molecular sieve and bulk silica gel may be obtained
in 55 pound drums. Should you require a mix of indicating silica gel and non-indicating
silica gel this item is available as well. Please ask about custom formulations if that
is something you currently require.
Bulk orange silica gel (no cobalt chloride) is now available in 5lb and 55lb containers
as well as a new 1lb can of indicating molecular sieve!

Montmorillonite is a relatively rare segment of the bentonite family with superior adsorption characteristics at low relative humidity. Even at 80% RH, it can pick up (adsorb) as much as 27% of its weight.

Molecular sieves retain their ability to adsorb water molecules over a much wider spectrum of temperatures than other
desiccant materials. Molecular sieves also have a much higher equilibrium capacity for water vapor under very low humidity
conditions. Molecular sieves contain a uniform network of crystalline pores and empty adsorption cavities, which give it an
internal adsorptive surface area of 700 to 800 gm2 (1/2 the total volume of the crystals). Because of its uniform structure,
molecular sieves will not desorb moisture into the package as readily as silica gel or clay as temperatures rise.
Unlike indicating silica gel, which turns from blue to pink as it becomes saturated with moisture, indicating molecular
sieve turns from blue to beige
