Batch foaming of hot melt extruded excipient/disintegrant/API pharmaceutical formulations and the study of the effects of the resulting cellular structures on API dissolution
… from HPOM images, are intact after both HME and batch foaming processing. In the second part of this research, a batch foaming process is carried out on the milled hot melt extrudated formulations. Scanning Electron Microscopy (SEM) is used to characterize the resulting cellular structure. The …

Linking Thermophysical Transitions and Rheological Properties to Polymer Foaming Outcomes with Carbon Dioxide
… fluids as physical blowing agents for polymer foaming is driving a renewed need for the fundamental understanding of polymer thermophysical and rheological properties in the presence of dense fluids. In particular, carbon dioxide is often studied as a physical blowing agent because of its …

Mechanisms of Cell Nucleation, Growth, and Coarsening in Plastic Foaming: Theory, Simulation, and Experiment
… growth and coarsening mechanisms during plastic foaming processes. Enforced environmental regulations have forced the plastic foam industry to adopt alternative blowing agents (e.g., carbon dioxide, nitrogen, argon and helium). Nevertheless, the low solubilities and high diffusivities of these …

Benign Processing of High Performance Polymeric Foams of Poly(arylene ether sulfone)
… of high performance polymer foams via a benign foaming process. The first goal of this project was to develop a process and the conditions necessary to produce a low density (>80% density reduction) foam from poly(arylene ether sulfone) (PAES). Water and supercritical carbon dioxide (scCO2) were …

Properties and foaming behaviour of thermoplastic olefin blends based on linear and branched polypropylene
… including foam processing and extrusion foaming. The main objective of the thesis is to provide a detailed investigation on the rheological, morphological, thermal, mechanical and foaming properties of isotactic polypropylene / high melt strength branched polypropylene homopolymer blends, …

Advancing the technology development for better quality wood plastic composites: process ability study
… addition does not have a significant effect. Foaming of WPC, which can enhance their properties, was investigated through studying the effect of heating time and temperature on void fraction and cell density.
