VAPLOK™ Desiccants are made of Montmorillonite (bentonite) Clay or Silica Gel desiccant material packaged in printed, non-dusting, sulphur-free Tyvek® substrates.


Advantek VAPLOK™ Desiccants are available in several formats designed for small and large applications. Bag sizes vary from 1/3 unit packs to 8 unit packs. A unit of desiccant (33 grams) refers to its drying capacity, not its volume, and is the amount of desiccant which will absorb at least 3 grams of water vapor at 20% relative humidity and at least 6 grams of water vapor at 40% RH at 77F (25C). The product is shipped in airtight packaging to prevent exposure to moisture.
