Molecular Sieve
Molecular Sieve Unit Paks are available in a variety of sizes and quantities and are housed in a Tyvek substrate.
Molecular Sieve is the most aggressive and expensive desiccant and comprised of a manufactured crystalline version of zeolite containing a network of uniform pores and empty cavities. Tyvek is extremely strong and hard to tear, non-dusting and has superior print quality.
These Molecular Sieve Unit Paks meet Mil Spec 3464 Type I & II, as well as DIN55473 compliant for direct food contact and can be used in a wide range of industries from military/government to consumer applications.
Available in a variety of quantities and sizes, the term "unit" is a quantity of desiccant, which will absorb a set percentage of its weight at certain levels of humidity.
Indicating silica gel is a silica gel bead or granule that has been washed with a concentration of cobalt chloride ( a heavy metal salt). The cobalt chloride is a deep blue color when it is dry and turns from blue to purple to pink as it becomes saturated with moisture. Typically, the color changes as the desiccant goes past 8% moisture levels (by weight) and indicates it is time to replace the desiccant.
The most typical use for an indicating silica gel is for a moisture sensitive product that will be inspected regularly as it gives a quick visual indication of how well it is doing. Because of the addition of cobalt chloride, indicating silica gel should not be used in contact with products for consumption such as food or pharmaceuticals.
The Dri-Box canister is packed with an indicating silica gel that is regenerable. Instead of replacing the desiccant inside, heating the canister will reverse the adsorbing action and allow the material to be reused.
