“…The formed carbon layer covers the polymer and prevents combustible gases from entering the flame zone. [51,52] In summary, the flame retardant mechanism of Sb 2 O 3 in conjunction with DBDPE is primarily gas phase flame retarding, accompanied with condensed phase flame retarding. [33] EVA composites containing Sb 2 O 3 and DBDPE particles with the loading of 12-40 wt% achieved a high LOI value and excellent fire burning rating to meet fire retardant requirements.…”

A high near-infrared (NIR) reflective cooling compound with flame retardant characteristics was fabricated by incorporating antimony trioxide (Sb 2 O 3 ) and decabrominated diphenyl ethane (DBDPE) into ethylene-vinyl acetate copolymer (EVA). The solar reflectivity and cooling capacities of the control sample and EVA compounds with either Sb 2 O 3 or DBDPE, and EVA composites embedded with Sb 2 O 3 and DBDPE, were evaluated by ultraviolet-visible-near infrared analysis and temperature tests. The effect of Sb 2 O 3 and DBDPE on the flammability, thermal behavior, and mechanical properties of EVA copolymer were determined via the UL-94 burning test, limiting oxygen index (LOI), differential scanning calorimetry, thermogravimetric analysis, and tensile and tearing tests. Compared with the glass blank, EVA compound filled with 10 wt% Sb 2 O 3 and 30 wt% DBDPE showed a roughly 17.3 C and 38.0 C decrease during sunlight exposure and in indoors, respectively, accompanied by the maximum NIR reflectivity of 68.8% in all as-prepared blends. Moreover, this as-prepared compound met a UL-94 V-0 classification and reached a LOI value of 29.3%. Notably, the singular addition of either Sb 2 O 3 or DBDPE improved the cooling capability of EVA but rarely fulfilled the fire retardant demand. In contrast, the incorporation of Sb 2 O 3 and DBDPE improved the desirable cooling and flame retardant properties.

“…One of the most frequently used engineering polymer is acrylonitrile-butadiene-styrene (aBs). This is due to its good mechanical properties, chemical resistance, easy processing, good surface quality of aBs parts, possibility of use in advanced applications, as well as good quality-price correlation [1][2][3][4][5][6][7][8][9][10][11]. aBs is used in various branches, such as: automotive, electrical or electronic [6][7][8][9].…”

Influence of flame RetaRdant and PRocessIng condItIons on selected PRoPeRtIes of mouldIngs made of aBsThanks to dyeing of polymers, the possibilities of their use are constantly increasing. It is equally important to use additives that will have several functions. a perfect example is titanium dioxide used as an optical brightener and a flame retardant at the same time. Mostly it is used in the form of a powder. However, there are no studies where TiO 2 is used as a colourbatch based on the different polymer matrix.The aim of the work was to investigate the effect of titanium white in the form of colourbatch on the flammability and selected properties of mouldings produced in various processing conditions. Colourbatch based on Ps matrix, was used in the research. The variable processing parameters were: injection temperature T w , volume flow rate V w , residence time and the addition of a colourbatch. On the basis of the measurements, it was found that the processing conditions and the addition of the colourbatch have low effect on the hardness of the mouldings, which was in the range from 75.59 o sh D (shore type D) to 81.95 o sh D. It was also noted that the addition of colourbatch with TiO 2 and increasing injection temperature reduces impact strength even by several dozen percent. Moreover, it was found that use of TiO 2 causes a delay in the ignitability of the samples in selected cases. It is difficult to determine whether the variable processing conditions or the addition of TiO 2 on the Ps matrix have a greater impact on the ignitability of the moulded parts.

“…As a general thermoplastic, acrylonitrile‐butadiene‐styrene (ABS) resins are widely used in electronic industry, light industry, and automobile industry due to its outstanding properties such as mechanical properties, chemical resistance, and good processing characteristics . However, the ABS resins can burn easily in the air and release a large amount of smoke and toxic gases, which limit its potential applications in many fields.…”

In this paper, three different kinds of typical transition metal molybdates (AMoO 4 , A = Co, Ni, Cu) were synthesized via a hydrothermal method. X-ray diffraction and scanning electron microscopy (SEM) were used to characterize their structures. Then, the synthesized molybdates were incorporated into acrylonitrile-butadiene-styrene (ABS) matrix via a masterbatch-based melt blending method. SEM images showed that transition metal molybdates (AMoO 4 , A = Co, Ni, Cu) are homogeneously dispersed in the ABS matrix. Thermogravimetric analysis (TGA) results indicated that the introduction of these transition metal molybdates (AMoO 4 , A = Co, Ni, Cu) could accelerate the degradation of ABS, especially for the CuMoO 4 . The initial thermal degradation temperatures are decreased by 9-12°C for ABS/CoMoO 4 and ABS/NiMoO 4 composites. But for the ABS/CuMoO 4 composite, it is decreased by 45°C. Meanwhile, the peak of heat release rate is decreased by 10%-13% for ABS/CoMoO 4 and ABS/NiMoO 4 composites, and it is decreased by 26% for ABS/CuMoO 4 composite. Moreover, TGA/infrared spectrometry was used to investigate the smoke suppression effect of CuMoO 4 in ABS indirectly; it showed that the addition of CuMoO 4 inhibits the release of hydrocarbons, aromatic compounds, and CO and promotes the generation of CO 2 .
