Abstract: The influences of metal (iron, magnesium, aluminum, and zinc) on thermal properties for paraffin/intumescent flame retardants (IFR) as a phase change material were studied in this paper. Thermogravimetric analysis (TGA), thermogravimetric analysis Fourier transform infrared spectrometry (TGA-FTIR), microscale combustion calorimetry (MCC), cone calorimetry (CONE), and differential scanning calorimetry (DSC) were used to characterize the thermal properties of the sample. The results revealed that metal could affect the thermal degradation and increase the char yield for a paraffin/IFR system. The volatilized products for the combustible gases were decreased, and carbon dioxide was increased for paraffin/IFR with metal compared to that without metal. Also, the flame retardant efficiency of IFR in paraffin could be improved by adding metal. However, the changes of the thermal properties for the metal-PCM were not in accord with increasing metal in the paraffin/IFR system. Also, the flame retardant mechanism for paraffin/IFR with metal was proposed.
