Description

In this presentation, we will discuss the topic of accelerated aging, a ubiquitous tool used to ensure shelf and in-use stability over long time periods. This powerful collection of techniques allows prediction of potential aging issues that would be time consuming and costly to identify in “real time.” However, accelerated aging has limitations, and data generated in an accelerated study must not be used blindly. 

We will initially discuss various aging mechanisms in polymers, and the scientific assumptions that underpin the accelerated aging process. We will then review analytical techniques that can be used to screen material aging or infer acceleration factors, including a discussion of their weaknesses. 

Finally, we will present a case study comparing accelerated aging techniques to demonstrate the importance of careful experimental design when leaning on accelerated methods to predict material performance. Attendees will gain an understanding of the processes underpinning accelerated aging, and the key considerations for applying these data.
