Abstract This paper investigates alternative approaches to accurately calculate the cell size of solid polymeric foams by means of light scattering (LS) experimental data. To this end, static optical transmission measurements have been carried out in foams with different densities, cell sizes and based on different polymers. Using these data cell size has been calculated by solving numerically the diffusion approximation equation of LS that takes into account both scattering and absorption mechanisms. From the analysis performed we have proved that light absorption becomes significant in solid polymeric foams.
