Clay Desiccant(CARE DRY®/ Unit Pak®)

Characteristics

It has a strong ability of absorbing moisture at low humidity environment, especially under 40% RH, it can proof corrupt of metals effectively. The moisture-absorption rate is higher than the requirement of Japan Industry Standard( JIS-Z-0701).
It is a physical absorptive desiccant. After absorbing the moisture, it has no distortion caused by deliquescence. Contacting with water, it has no heat generated. It contains little water-soluble substances and the PH value of it is 7~8, almost neutral, so it will cause no corrosion to the metal.
As its raw material, clay is natural mineral and does not contain environmental management substances and meets RoHS.

Packaging Material

Type Packaging material
CAREDAY BMB It is no dust desiccant and meets TYPEⅠ&Ⅱ of U.S. Military Specification(MIL-D-3464). Using smooth and high strength non-woven fabric as surface and special blended non-through-hole PE non-woven fabric in the back, it can prevent the dust going through.
UNITPAK BF Made of paper / PE fiber / PE. It has the most suitable water permeability after using our special technology to punch a hole to polyethylene layer.
UNITPAK BD Use high bacteria blocking tyvek film, it is suitable for IT related clean workshops.

※:Tyvek is the brand of Du Pont USA.

Test of inner package humidity

51E8A273-8CC5-4FE6-9215-24AE22E384B4

Pack the silica gel and clay each 30g with the same packaging material and then put into the aluminum foil bag with 10pcs of QFP tray. Filling data recorder to measure the humidity inside the bag. At the end of the test, the equilibrium moisture in the aluminum bag sealed silica gel is 3.8% while clay sealed one is 0.1%. In the area of low humidity, the moisture absorption capacity of the clay desiccant is superior to that of silica gel.
