Molecular sieves retain their ability to adsorb water molecules over a much wider spectrum of temperatures than other desiccant materials. Molecular
sieves also have a much higher equilibrium capacity for water vapor under very low humidity conditions.
Molecular sieves contain a uniform network of crystalline pores and empty adsorption cavities, which give it an internal adsorptive surface area of 700 to 800 gm2 (1/2 the total volume of the crystals). Because of its uniform structure, molecular sieves will not desorb moisture into the package as readily as silica gel or clay as temperatures rise. Being synthetic rather than naturally occurring, molecular sieve is higher in cost per unit, but due to its extremely large range of adsorptive capabilities, it is often the best value.
