GAC-100 CONTAINER DESICCANTS
GAC-100 desiccant is a composite of a special kind of clay mineral
and calcium chloride.The clay mineral, made from a naturally
occurring deposits through precise treatments, has a large
water capacity with a unique three dimensional chain structure and a
special needle fiber crystal mould .in the high humidity
GAC-100 can work effectively as long as 40 days and remains
solid state while collecting 100% moisture of its own dry weight .
GAC-100 performs best at room temperatures between 30-50 ℃ and at
high humidity between 60to90% RH and will drop the relative humidity
in ocean-going containers to aroun 40% RH.
GAC-100 is packaged in double cover : the vacuum
bag (or barrier bag) and the cover stock
(spunbonded polyethylene material or TYVEK) which maintains an
acceptable adsorption rate. 2 or 10 or 100 packs of Gac-100
desiccants are put into a big vacuum bag (0.8mm nylong PE) for
transportation and storage.
GAC-100 has two types including granular shape and powder shape.
