Abstract: Polypropylene (PP) foams are commercially manufactured in four ways, with each method producing different characteristics. The aim of this paper was to examine the properties of each PP-based foam and compare their thermal behaviors and conductivities. A thermal constant analyzer was used to measure the thermal conductivity of the foam samples with the transient plane source (TPS) technique. Results showed that thermal conductivity varied for each production method, but density was the most influential variable that altered conductivity of the PP-based foams.
