Abstract: Synthetic polymers in starch-based polymer formulations improve the thermal and mechanical properties of the compounds. The purpose of this study was to develop and analyze foams containing ethylene-vinyl acetate (EVA) and varying concentrations of corn starch. A Hot Disk Thermal Constants Analyser measured the thermal conductivity of the EVA/starch samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of the blends increased with starch content. The porosities of all the samples were very similar, so the larger thermal conductivity enhancements that were observed for certain samples was due to a higher starch content.
