abstract="Both natural graphite (NG) and home-made expandable graphite (EG) were blended with polypropylene (PP) and intumescent flame retardant (IFR) by a melt process. The resulting composites contain filler of 1-5 phr (parts per hundred parts of PP-IFR). The limiting oxygen index (LOI) and thermal gravimetric analysis (TGA) were employed for the study of fire retardance. It shows that the incorporation of EG into systems of PP-IFR would impart flame retardance and thermal stability to the virgin formulation PP-IFR with optimal synergy at a loading of 2 phr, rather than the NG. The mechanical properties of the three systems and fracture surface morphology by SEM were also described.<p /><p>Language: en</p>",
