Chemical Engineering Seminar - “The Role of Rheology in Non-Pressurized Polymer Foaming Systems” by Maryam Emami, PhD
McMaster University, Hamilton, ON

ABSTRACT: Plastic foams, as engineering materials, are widely used in variety of industrial sectors and represent an extraordinary class of materials. Foaming in polymers involves delicate scientific mechanisms and unique morphology transformations. This work explores the influence of rheological properties on polymer foam development in non-pressurized systems. To understand the complex contributions of rheology on different stages of the foam processing in such systems, visualization studies were conducted using a polymer-foaming microscopy setup. Morphological analysis was used to determine the rheological processing window in terms of shear viscosity, elastic modulus, and melt strength, intended for the production of foams with greater foam expansion and more uniform bubble size distribution.
