Desi-Pak® Clay Desiccant

Desi Pak® clay desiccant bags contain a highly activated, chemically inert and non-corrosive desiccant which absorbs moisture vapor through the capillary action of adsorbent particles without changing the physical shape of the particles or the bag.

Desi Pak® unit bags exceed the requirements of Mil-D-3464E in actual performance and will exceed the moisture vapor adsorption of silica gel at government specifications levels. Desi Pak® montmorillonite clay is a naturally occurring mineral as opposed to the chemically synthesized adsorbent. Therefore it is more economical than silica gel or molecular sieve.

The Desi Pak® performance curve exceeds both the military specification, which is the industry standard, and the silica gel performance curve for these same specifications. At 20% RH, Desi Pak® will adsorb 50% more moisture than required by Mil-D-3464E, whereas silica gel will only adsorb 3.5% more moisture than required by Mil-D-3464E.

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.

Your most efficient and cost effective form of humidity protection during shipment and storage, Desi-Pak® clay desiccant bags are in stock and ready for immediate shipment from Texas Technologies.

USAGE

Desi Pak® is a low cost efficient clay desiccant which will protect the contents of a sealed container until it is opened. When used in conjunction with a humidity indicator, the contents of a sealed container will remain free from mildew or corrosion and will be in the same condition as when packaged for shipment or storage.

CLASS 100 Cleanroom Compatible

Desi Pak® Tyvek® bags were tested by an independent laboratory for Class 100 Cleanroom use. The 1/6, 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 cleanroom compatible.

Meets FDA Specifications

Desi Pak® Tyvek® activated clay desiccant bags meet the requirements of the U.S. Food and Drug Administration for use in contact with food and drugs.
