Bentonite clay is a naturally occurring mineral as opposed to a chemically synthesized absorbent. Therefore it is more economical than silica gel or molecular sieves. The performance curve exceeds both industry standards, and the silica gel performance curve for these same specifications.
At 20% RH, the activated clay bags will absorb 50% more moisture than required by industry standards, whereas silica gel will only absorb 3.5% more moisture than industry standards require. The packaging is sealed inside a waterproof and moisture vapour-proof container with the inclusion of a desiccant to prevent rust, mildew or corrosion damage. In Method II packaging, the package is maintained at a safe humidity below 40% RH during the normal storage period of 18 months to 2 years.
