Proper design of medical devices requires a thorough understanding of material properties throughout the manufacturing, distribution, and end‐use conditions. Widely used amorphous polymers deserve special attention. In this article, we will focus on the physical aging phenomenon. This process affects many important properties of materials. An improved Differential Scanning Calorimetry (DSC) technique was developed to quantify the extent and the kinetics of aging. Consequences of aging were also studied with physical testing and Scanning Electron Microscopy (SEM).
