Clay Desiccant Packets

Clay desiccants from IMPAK are chemically inert, dehydrating agents that prevent corrosion and mildew by ADSORBING moisture from the air of an enclosed space. In other words, clay desiccants are used to dehumidify the inside of your package. IMPAK’s clay desiccant offerings all meet Department of Defense military spec D-3464E for static dehumidification, just one way we insure the performance of our product.

The term "unit" refers to the quantity of desiccant that can absorb 3 grams of water vapor at 20% relative humidity or 6 grams of water vapor at 40% relative humidity level. A "unit" of Clay is typically 33 grams, and a "unit" of Molecular Sieve or Silica Gel is normally 28 grams.

Our clay desiccants primarily consist of Montmorillonite, a naturally occurring non-hazardous mineral made up of magnesium aluminum silicate. Ounce for ounce, clay is one of the most cost efficient ways to reduce moisture damage during shipping and transport of a product. Clay is arguably the most “green” or environmentally safe of all the typically used desiccants. This type desiccant can also regenerate for repeated use at very low temperatures without noticeable deterioration.

Because of Montmorillonite clay’s unique properties, it can be used with a variety of goods; everything from steel and metal components to military applications, electrical components, machinery, home storage and to keep guns and ammunition in top condition.

For pharmaceutical and lab applications, clay works great preserving diagnostic products.

The only downside to clay desiccants is that they stop pulling in moisture at temperatures above 120° F. At that point, they may actually give out moisture.
