Fire Properties of Acrylonitrile Butadiene Styrene Enhanced with Organic Montmorillonite and Exolit Fire Retardant

“…Guo et al [32] studied the influence of modified ammonium polyphosphate (APP) on the flame retardancy of wood floor composite by cone calorimetry and noticed a synergetic effect between APP and the composite followed by a good improvement on the overall flame retardancy of the multicomponent material. Similar results were outlined also by other research groups (please see for example Realinho et al [1], Xia et al [26], Lu et al [27], Despinasse and Schartel [28], Ma et al [33]).…”

“…Several formulations were prepared (see Table 2) and all the materials were first dried at 100 C for 24 h than were mixed at a blending temperature of 205 • C in a Brabender mixing chamber (Brabender, Germany), with a rotating rate of 60 rpm applied for 10 min. The materials final composition was chosen according to the open literature [1][2][3][4][5] and with the scope to determine the most favorable minimum addition of OMT and fire retardants in order to get the best fire properties. The specific specimens used for further tests were obtained at 205 • C in a Carver press over three minutes at a pressure of 50 atm and two minutes at 150 atm.…”

“…Consequently, improving the fire-retardant behavior of polymers is of critical importance for specialists. Many authors have combined ABS with different fire retardants [1][2][3][4][5][6][7][8][9][10][11][12] as well as different clays in order to enhance the synergy between the components [13]. One of the most used clays is the organic montmorillonite (OMT) [13].…”

“…Therefore, according to the literature recommendations, in this research a recycled ABS (reABS) was acquired and improved by adding 1%-2% organic montmorillonite and 15%-20% fire retardants. The nanometer sized montmorillonite clay particles can enhance surface integrity and provide advantages over the thermal properties of the composites, while the Exolit fire retardants [1,6] are well known for their capability to decrease the heat released in a fire. These new developed materials were tested with regard to their fire properties by means of the Limiting oxygen index (LOI), UL 94, and cone calorimeter methods.…”

Mechanical property improvement and fire hazard reduction of ammonium polyphosphate microencapsulated in rigid polyurethane foam

“…The results showed that nanocomposites with 30 phr APP achieved the flammability rating of V‐1 and limiting oxygen index (LOI) of 29.2% and also had the highest thermal stability. Realinho and fellows reported that condensed‐phase activity via charring and residue formation in acrylonitrile‐butadiene‐styrene copolymer containing APP was observed. Rajaei investigated the combined effects of APP and talc on the fire and mechanical properties of epoxy/glass fabric composites.…”
