We present a sharp-interface algorithm for simulating the diffusion-driven bubble growth in polymer foaming. A moving mesh of unstructured triangular elements tracks the expanding and deforming bubble surface. In the interior of the liquid, the mesh

During polymer foaming with physical blowing agents, plasticization affects the melt viscosity, gas diffusivity in the melt, and the gas–melt interfacial tension. In this paper, we propose a model for plasticization during bubble growth, and estima

In the United States, HCFC-141b was phased out of urethane foam applications on January 1, 2003. Zero ozone depletion potential (ODP) alternatives, such as hydrofluorocarbons (HFCs) and hydrocarbons (normal pentane, isopentane, and cyclopentane), hav

The cell size distribution in a thermoplastic foam to a large extent determines its mechanical and thermal properties. It is difficult to predict because of the many physical processes involved, each affected in turn by an array of factors and parame

The rate of disproportionation of trichloromethyltin in various solvents was studied by two methods, derivatization with sodium tetraethylborate and 13C NMR measurements, which gave similar results. The reaction followed second-order kinetics and was
