TL;DR: In this article, two typical building-used polymer wastes, extruded polystyrene (XPS) and rigid polyurethane (RPU), were selected to conduct a series of thermogravimetry (TG) experiments.

TL;DR: The aim of this work was motivated by the research of sample width and thickness effects on upward flame spread behavior, including flame spread rate during acceleration propagation for different sample thickness and width, theoretical global mass loss prediction based on Emmons's hypothesis, and dimensionless flame height scaling with dimensionless heat release rate for steady stage burning.

TL;DR: In this article, a series of thermogravimetry (TG) analysis with four heating rates (5, 10, 15, and 20°C/min) in nitrogen was performed to calculate the activation energy of extruded polystyrene (XPS).

TL;DR: In this paper, a waste rigid polyurethane (RPU) was selected to conduct thermogravimetric analysis experiments with four different heating rates, and thermal degradation kinetics were analyzed by model free, model fitting, and distributed activation energy model (DAEM) fitting methods.

TL;DR: In this article, the authors explore the mechanisms of horizontal flame spread over thermal insulation foam surfaces, extruded polystyrene and expanded poly styrene foams were selected to carry out a series of experiments with different sample widths ranging from 4 to 16 cm.
