Small Desiccant Packets

IMPAK is a world leader in the production and distribution of moisture adsorbing desiccants. With over 100 different desiccant products, the ability to create custom blends (for instance, by mixing activated carbon with silica gel, we can create a desiccant product capable of adsorbing both odor and moisture), and competitive pricing, your options are virtually endless.

If you have an application that requires product specifications or a blend not listed here, contact us at: (310) 715-6600

Please note that the information on this page is not meant to be exhaustive. For a more thorough overview, please refer to our Desiccant Guide page.


Silica Gel Packets

Non-Indicating Silica Gel is effectively the same as Indicating Silica Gel, except that it is white and does not change color when it has reached its moisture adsorption capacity.

Indicating Silica Gel changes color when it has reached its moisture adsorption capacity. Indicating Silica Gel is extremely efficient at temperatures below 77°F (25°C).

Molecular Sieve Packets

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. Being synthetic rather than naturally occurring, molecular sieve is higher in cost per unit, but due to its extremely large range of adsorptive capabilities, it is often the best value.
