Abstract: Minerals are often added to polypropylene (PP) foams to improve thermal conductivity. The aim of this study was to test and compare the thermal conductivity of unfilled, magnesium hydroxide (Mg(OH)2)-, and montmorillonite (MMT)-reinforced PP foams. An analyzer measured the thermal conductivity of the polypropylene foams using the Transient Plane Source (TPS) method. Results showed that thermal conductivity increased with foam density and with magnesium concentration.
