Objective: In this study, we demonstrate synthesis polyurethane closed cell foam via a simple chemical method. Material and Methods: The chemicals used in the study included polyol, foaming agent, silicon oil, and other additives. Characterization methods included X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), elemental map, and Fourier transform infrared spectroscopy (FTIR). Result: The results of the analysis showed that the obtained foams were successfully synthesized. The cells in these foams were mostly closed, and were micrometric in size. Trace elements were homogeneously distributed in synthesized foams. Conclusion: The results of this study are expected to be useful for the engineering application of this type of foam.}, keywords = {Polyurethane,Closed cell foam,Chemical Method,Synthesis}, url = {https://www.jourtm.com/article_110062.html}, eprint = {} }
