Flame-retardant properties of ammonium polyphosphate (APP) and its two microcapsules, APP with a shell of melamine–formaldehyde (MF) resin (MFAPP) and APP with a shell of epoxy resin (EPAPP), were studied in styrene–butadiene–styrene (SBS). The results indicate that APP after the microencapsulation leads to an increase in limiting oxygen index in SBS compared with APP. When dipentaerythritol is incorporated into the SBS composites containing the APP microcapsules, a further improvement in flame retardancy of the composites is observed. The microencapsulation does not result in much improvement of mechanical properties. Moreover, the effect of a compatibilizer (SBS grafted with maleic anhydride) on flame-retardant and mechanical properties of SBS/APP composites was investigated.

In this study, nanocomposite foams based on styrene-butadiene-styrene (SBS) copolymer and nanosized calcium carbonate (CaCO3) were prepared using chemical blowing agent (modified Azodicarbonamide) by compression molding at (230°C) temperature and (30MPa) pressure. The effect of nano CaCO3 concentration on cell nucleation rate, foam density, morphology and mechanical properties were studied for all samples. It was found that foam morphology and strength affected by nanofiller addition and its concentration. The results showed that SBS nanocomposite foam with 5 phr of CaCO3 nanoparticles have more cell density and smaller size cells compared with another samples. mechanical properties in compressive mode for foams were improved by increasing nano calcium carbonate content.
