“…This appears due to the weak thermal stability of OMT and FR, while when these two components are used together a synergy between them occurs and TTI times of nanocomposites are improved. On the other hand, Zhang et al [45] who used a cone calorimeter with a heat flux of 35 kW/m 2 , obtained a time of ignition of 39 s for pristine ABS and 51 s for ABS with 30% APP filler. Other researchers, as Wu et al [46], obtained a TTI of 24 s for ABS with a 50 kW/m 2 external heat flux, which is in line with our result.…”

In this paper an experimental investigation on fire retardancy of a new polymer nanocomposite derived from organic montmorillonite and exolit fire retardant in an acrylonitrile- butadiene-styrene copolymer by analyzing the flammability and fire behavior is described. The samples were prepared by melting and mixing nanocomposites and fire retardant in different concentrations in an acrylonitrile-butadiene-styrene base polymer. It was found that using only one component (organic montmorillonite or fire retardant) the burning stops in 10 s on the sample. Confirmation of synergy in flammability by combining both montmorillonite and flame retardants was noticed and is discussed regarding the flame-retardant mechanisms assessed by means of the Limiting oxygen index (LOI), UL 94, and cone-calorimeter methods. The acrylonitrile- butadiene-styrene preparation with 15–20 wt% fire retardant and 1–2 wt% organic montmorillonite reached a UL-94 V-0 classification, contrasting with the pure acrylonitrile- butadiene-styrene and the acrylonitrile-butadiene-styrene with 15 wt% fire retardant and acrylonitrile-butadiene-styrene with 1–2 wt% organic montmorillonite formulations, which completely burned. Finally, the samples showed a very good synergy going to a higher reduction of the peak heat release rate and to a minimum mass reduction, as obtained from cone calorimeter tests.

A novel flame retardant system, ammonium polyphosphate (APP), and expandable graphite (EG) with a new carbon source, poly(diphenolic phenyl phosphate) (poly(DPA‐PDCP)), derived from biomass has been proven to be effective in preventing melting drip and improving flame retardancy of acrylonitrile–butadiene–styrene copolymer (ABS) in this study, which was manifested by limiting oxygen index (LOI) and vertical flammability (UL‐94) tests. The optimal synergy was exhibited at a loading of 30 wt % of three flame retardants in a proper ratio (APP/poly(DPA‐PDCP)/EG = 12/3/15). Thermogravimetric analysis result indicated the char residue and the thermal stability could be enhanced because of the synergistic effect of APP/poly(DPA‐PDCP)/EG, which is elaborated by a hypothesis of flame retardancy mechanism of the three components. The morphologies of cross‐section and char residue by SEM were also described. The dynamic mechanical analysis implied that APP/poly(DPA‐PDCP)/EG together can enhance the dynamic mechanical property of ABS. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
