“…The dehydroxylation of γ-AlOOH is known to occur at higher temperatures and is accompanied by a theoretical weight loss of 15%. These results are in good agreement with literature [27]. No significant deviation in TGA data is observed even after 25 cycles, which confirms the thermal stability of the material even after repeated regeneration cycles.…”

One of the drawbacks of poly(methyl methacrylate) (PMMA) is its flammability. This limits its use in many areas, particularly in constructions. Although there are several fire retardants commercially available, certain disadvantages remain. Introduction of fire retardants into PMMA can change the mechanical properties and transparency can be significantly reduced. Our attention in this study was focused on aluminium trihydroxide (ATH) nanoparticles as the filler for PMMA. To achieve better compatibility and avoid the agglomeration of nanoparticles, 2‐hydroxyethyl methacrylate was used as a co‐monomer for nanocomposite preparation. The characteristics of sheets made with ATH nanoparticles were compared to standard PMMA sheets prepared without additives. Better thermal properties and impact hardness were observed, the speed of burning was significantly lower, while complete transparency of the material was retained. POLYM.

“…These show that composites reinforced with boehmite exhibit higher fire resistance in comparison with pure poly(methyl methacrylate) [12], improve the char-forming property in ethylene vinyl acetate copolymers [9] and combined with phosphorous-based additives in polycarbonate/acrylonitrile-butadiene-styrene enhance the barrier layer of the fire residue during the combustion [13]. It has been also reported that modified boehmite with tributyl phosphate reduces the peak heat release rates and the time of ignition of polyurethanes [14].…”

SUMMARYThis paper explores the use of boehmite as a fire retardant in low-density polyethylene and polyamide 6. The structure and morphology of the filler are characterized by X-ray diffraction and scanning electron microscopy. The water content of our boehmite is estimated about 30% by thermogravimetric analysis. The filler/matrix interactions in nanocomposites are investigated by means of thermo-physical measurements: differential scanning calorimeter and thermogravimetry. The resulting morphology shows particles individually dispersed in the matrix. The fire tests present a fire-resistance effect at low filler content despite a different behavior as a function of the matrix. For instance, with only 2% volume of boehmite, the burning time of LDPE composite is significantly increased by 15%. At the same filler content in PA6, the burning time is solely increased by 4.5%. On the other hand, the limiting oxygen index is increased by +7.0% (only 2.6% with LDPE composites).
