Fire resistance finishing of thermoplastics as represented by the example of polystyrene

Fire resistance finishing of thermoplastics as represented by the example of polystyrene. Kerscher, Utto (Chem. Fabr. Kalk G.m.b.H., Cologne, Ger.). Nehorlavost Polym. Mater., 90-9. Dom Tech. SVTS: Bratislava, Czech. (German) 1976. CODEN: 36QXAU. DOCUMENT TYPE: Conference CA Section: 36 (Plastics Manufacture and Processing) Mixts. of hexabromocyclododecane [25637-99-4], nonabromobiphenyl (I) [27753-52-2], or decabromodiphenyl ether [1163-19-5] and Sb2O3 were useful fireproofing agents for styrene polymers, e.g., a styrene polymer contg. 16% 7:3 I-Sb2O3 mixt. had a rating of V-0 in burning tests (UL 94). The fireproofing agents had little effect on the other properties of the polymers. The toxicity of the combustion gases of the polymers was not increased by the fireproofing agents.

Solid products from the thermolysis and combustion of polyolefin compositions containing synergistic antimony trioxide-based mixtures. Bordanova, V. V.; Klimovtsova, I. A.; Filonov, B. O.; Fedeev, S. S.; Surtaev, A. F.; Lesnikovich, A. I.Some commonly used reagents like 87-82-1 and 9002-88-4 are used in this experiment. (Nauchno-Issled. Inst. Fiz.-Khim. Probl., Minsk, USSR). Vysokomol. Soedin., Ser. B, 29(1), 42-5 (Russian) 1987. CODEN: VYSBAI. ISSN: 0507-5483. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) The thermal decompn. and combustion products of low-d. and high-d. polyethylene [9002-88-4] and polypropylene [9003-07-0] with binary synergistic fireproofing agent mixts., consisting of Sb2O3 and chloroparaffins C27H31Cl25, Barmilon [85188-60-9] (C15H6Cl12), hexabromobenzene [87-82-1], or hexabromocyclododecane [25637-99-4] were detd. The concns. of Sb oxyhalides (Sb4O5Br2, SbOCl) and Sb2O3 were detd. by x-ray diffraction, and the total concn. of Sb was detd. by at. emission spectroscopy after dissocn. in PhCl and PhMe. The fireproofing effectiveness of synergetic halohydrocarbon mixts. can be increased by accelerating the reaction of HCl with Sb2O3 to oxyhalides ensuring the transition of Sb halides in the gaseous phase and preventing the formation of metallic Sb. .
