MIL-D-3464E desiccants, typically made from clay or silica gel, are used in electronics and come in sizes from 1/6 to 32 units.
At 20% RH, activated clay absorbs 50% more moisture than the standard requires, while silica gel absorbs 3.5% more.
These desiccants meet military packaging standards (MIL-P-116-E) for preserving items in moisture-proof containers, preventing rust and mildew, and keeping humidity below 40% RH for 18 months to 2 years.
