Study on Recycling ABS Plastic/Nano CaCO3 /TiO2 /POEModified Composites

High filler content acrylonitrile‐butadiene‐styrene composites containing tungsten and bismuth oxides for effective lead‐free x‐ray radiation shielding

“…Despite the good polymer/filler interfacial adhesion evidenced by morphological analysis, this effect cannot be avoided, particularly for isodimensional particles such as those used in this work, as the particles inevitably act as stress concentration points during fracture propagation in the polymer matrix 46 . However, the detrimental effect of the fillers on the flexural strength of the composites is not dramatic, and the composite still shows flexural strength values comparable to other ABS composites filled, for instance, with calcium carbonate or titanium dioxide particles 47 …”

“…46 However, the detrimental effect of the fillers on the flexural strength of the composites is not dramatic, and the composite still shows flexural strength values comparable to other ABS composites filled, for instance, with calcium carbonate or titanium dioxide particles. 47 As concerning Shore D hardness measurements, whose results are reported in Table 2, the addition of the inorganic fillers induces a progressive increase in TGA analysis in non-oxidative conditions was also carried out on the prepared samples to evaluate the effect of filler addition on the thermal stability of the polymer phase. Results are summarized in Table 2.…”

Cooperative Effect of Chemical and Physical Processes for Flame Retardant Additives in Recycled ABS

“…A list of the composition of the samples is listed in Table 1. References [2][3][4][5] were prepared using only one FR to study the effect of each additive, while the references [6][7][8][9][10][11] were prepared by mixing two different FR additives to study potential synergies between them. The total amount of additives in the samples was kept constant throughout the experiments (15 wt.%).…”

“…The best modulus values were obtained for the references containing SEP. The SEP-based material (Reference [5]) was the composites with the highest modulus value, representing an increase of 37%, while the references based on a mixture containing SEP (References [8,10,11]) presented values centered on 3500 MPa (≈ 30%). The increase in modulus values is due to the addition of the inorganic particles, which provides stiffness to the starting rABS.…”

“…[9,10]. Several studies have been carried out on recycled ABS in terms of improving thermo-mechanical properties by using nanoclays or other virgin polymers [11,12]. However, studies focusing on improving the flame retardant properties of recycled polymers are scarce [13][14][15][16][17].…”
