Molecular sieves retain their ability to adsorb water molecules over a much wider spectrum of temperatures than other desiccant medias. Molecular sieves also have a much higher equilibrium capacity for water vapor under very low humidity conditions.

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 large range of adsorptive capabilities, it is often the best value.

Why is Molecular Sieve the best desiccant?
