He is actually looking for information relative to holding a specific humidity +/- a small percent. So he needs a material that will both absorb when the RH is above the set point and smoothly release when the RH is below the set point. From your material, it appears that your products are absorption only. The process of regeneration appears to be the process for removing the water from the bead, which indicates to me that it locks what it has absorbed and so will have a limit/lifetime. Of course, I may be misinterpreted this statement from the 3A page:

3A Molecular Sieve regenerated and reused. To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate 3A Molecular Sieve heat to 250℃.

The application (humidity control for cigars) does not lend itself to periodically raising the temperatures to 250*C. Still, I really like your product and your MSDS is excellent!
