Abstract: This article focused on determining the extinction coefficient of polyolefin foams. A combination of experimental and theoretical methods were used to accomplish this goal. Samples differed from each other in terms of thickness, chemical composition, colour, density, and structural characteristics. Fourier transform infrared spectroscopy was used to measure transmittance spectra. Thermal conductivity of the foams was also measured. The researchers concluded that cell size was the primary factor affecting the extinction coefficient.
