MIL-Spec Desiccant Bags
Pricing and ordering information
Desi Pak ®
packaged clay desiccant is a low-cost, efficient desiccant which will protect the
contents of a properly sealed container during shipping and storage. The contents of a
sealed container will be in the same condition as when it was packaged for shipment or
storage.
 The addition of a humidity indicator card in each
Desi Pak container allows the container to be visually inspected to insure that the
desiccant remains active and the contents safe.
Desi Pak unit bags exceed the requirements
of Mil-D-3464 in actual performance and will exceed the moisture vapor adsorption of
silica gel at government specification levels. Desi Pak montmorillonite clay is a
naturally occurring mineral as opposed to a chemically synthesized adsorbent. Therefore it
is more economical than silica gel or molecular sieve.
The Desi Pak performance curve exceeds both
military specification, which is the industry standard, and the silica gel performance
curve for these same specifications.

At 20% RH, our
Clay Desiccant Packs will
adsorb 50% more moisture than required by Mil-D-3464, whereas silica gel will only adsorb
3.5% more moisture than required by Mil-D3464.
Mil-D-3464E Specification
Desi Pak meets Method II packaging
standards described in Mil-P-116-E, which covers the basic requirement of military
packaging methods of preservation. This involves packaging an item inside a sealed
waterproof and moisture vapor-proof container with the inclusion of a desiccant to prevent
rust, mildew or corrosion damage. In Method II packaging, the package is maintained at a
safe humidity below 40% RH during the normal storage period of 18 months to 2 years.
The part on the left has not
been protected by Desi Pak® and shows signs of moisture-induced corrosion. The
part on the right has been properly protected with Desi Pak.

| Tyvek®
Desi Pak Tyvek® bags, a
United Desiccants' innovation in the industrial desiccants market, are non-dusting. Tyvek®
bags contain no sulphur. Sulphur when placed in contact with a product, may cause
corrosion in many applications such as the electronics industry. Tyvek® is
made from high density polyethylene fibers, is a spunbonded olefin, and is extremely
tear-resistant. Mil-D-3464 dust testing has yielded a result of less than 0.5 mg of dust -
truly a dust-free desiccant.
Class 100 Clean Room Compatible
United Desiccants' Desi Pak Tyvek® bags
were tested by an independent laboratory for Class 100 Clean Room use. The 1/8, 1/2, 1/3,
1, 2, 4, and 8 unit bags containing clay desiccant were evaluated. All bags tested emitted
less than 100 particles (0.5 microns in size or larger per cubic foot of air), thereby
certifying Desi Pak bags as Class 100 Clean Room Compatible. |
Tyvek® is a DuPont registered
trademark.
Meets FDA Specifications
Desi Pak Tyvek bags meet the requirements
of the U.S. Food and Drug Administration for use in contact with food and drugs. |

No matter how much care is exercised in producing a desiccant, it
is only effective when it is active. Each pail or drum contains a humidity indicator card
to insure that the desiccant is active when received and opened. To insure that the
desiccant remains active it is essential that the liner be tightly resealed in its
container.
