Virtually all materials interact more or less strongly with humidity. The knowledge of moisture induced changes of the material properties is a key issue in decisions related to processing, packaging, storage and shelf life of a product. |

The Moisture Sorption Isotherm
|
The representation of the changes in the water content of a sample as a function of the relative humidity at constant temperature is called
the water vapor sorption isotherm. It is the simpliest and best way to demonstrate the interactions of a material with moisture. From the Quantity and the course of the isotherm fundamental material properties and important information about its handling can be derived. Sorption/desorption events are generally complex physico-chemical processes and cannot be predicted, why water vapor sorption isotherms must be determined experimentally examples >> |
