Absorption of Thermal Radiation by Burning Polymers



Gregory T. Linteris, Mauro Zammarano, Boris Wilthan, Leonard M. Hanssen


In large-scale fires, the input of energy to burning materials occurs predominantly by radiative transfer. The in-depth absorption of radiant energy by a polymer influences its ignition time and burning rate. The present investigation examines two methods for obtaining the absorption coefficient of polymers for infrared radiation from high-temperature sources: a broadband method and a spectral method. Data on the broadband absorption coefficient for two thermoplastics, poly(methyl methacrylate)and polyoxymethylene are presented, and they are found to vary with thickness. Implications for modeling of mass loss experiments are discussed.
