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.

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.
