Hygroscopic Materials

A hygroscopic material has the ability to adsorb and store moisture from the surrounding air. When the RH changes, a difference in the vapour partial pressure results in the material absorbing or desorbing moisture in order to reach equilibrium. Most materials have a hygroscopic potential which is too low to have any impact on indoor […]
