Foaming is a complex phenomenon, where several mechanisms, such as nucleation, growth, and stabilization of the cellular structure, play a key role. Understanding these mechanisms is essential for producing foams with tailored properties. The webinar will focus on two key aspects of foaming mechanisms:

Nucleation: This section will address the influence of processing parameters and different nucleating agents on the foaming process. We will explore how the choice of nucleants and the control of process parameters can significantly impact the nucleation stage, which is critical for determining the final foam structure.

Growth and Stabilization (Foamability): In this part, we will discuss the mechanisms involved in the growth of bubbles and the stabilization of the foam structure, commonly referred to as foamability. We will explain how factors such as viscosity, strain hardening, and crystallization temperature affect the foam’s cellular structure and density.

Additionally, we will present the experimental techniques used to analyze and quantify these mechanisms, both ex-situ and in-situ. Techniques such as optical expandometry, X-ray radioscopy, infrared expandometry, and in-situ FTIR will be highlighted to demonstrate how they provide insights into the dynamics of foaming processes.

Several case studies will also be presented to show how this knowledge is applied in real industrial settings.
