The effects of fullerene (C₆₀) and aluminium hydroxide (ATH)/C₆₀ combination on the thermal stability, flame retardancy and mechanical properties of styrene- butadiene- styrene block copolymer (SBS) were investigated. Adding small amount (0.5 wt.% - 2 wt.%) of C₆₀ into SBS matrix raised the initial decomposition temperature of the composites slightly, while C₆₀ alone had little influence on the flame retardant behavior. In SBS/ATH/C₆₀ system, however, the addition of C₆₀ significantly improved the UL-94 vertical combustion grade and limiting oxygen index (LOI). The total content of the flame retardant in SBS/ATH/C₆₀ system (56 wt.%) was lower than that in SBS/ATH system (60 wt.%) when UL-94 reached V0 level. Consequently, the adverse effects on the mechanical properties due to the high level of flame retardant loading reduced. Meanwhile, the data obtained from cone calorimetric test indicated that C₆₀ can not only reduce the heat release rate, but also raise the char residue of SBS/ATH composites.
