  Mil-D-3464E is the U.S. military specification for silica gel and clay desiccants. It includes requirements for the desiccant performance and packaging, as well as specific test procedures. Desiccant Bags are desiccants that are packaged in porous materials such as Kraft Paper or Tyvek. Desiccant bags absorb moisture, odors and chemicals to preserve and protect your products such as semiconductors, electronics, cartons of food, and all types of machinery.

  A “Unit” refers to the Military Specification for packaging of desiccants. The term unit is a quantity of desiccant, which will absorb a set percentage of its weight at certain levels of humidity.

  Mil-D-3464E defines a “Unit” as the amount of desiccant needed to adsorb:

  ◆3 grams of water at 20% RH, 25℃, and

  ◆6 grams of water at 40% RH, 25℃.

  ◆A unit is also roughly equivalent to one ounce.
