| Abstract: | A submicrometer mesoporous structured iron–tin oxide hydroxide [FeSnO(OH)5] was synthesized via a hydrothermal method and characterized by X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and the Brunauer–Emmett–Teller method. Blank poly(vinyl chloride) (PVC) and a flexible PVC treated with FeSnO(OH)5 were investigated by limiting oxygen index (LOI) testing, cone calorimetry testing (CONE), tensile properties testing, and thermogravimetric analysis (TGA)–differential scanning calorimetry. The PVC sample treated with 5 phr FeSnO(OH)5 (PVC5) showed the best integration properties among the studied samples. Compared with those of the untreated PVC sample, the LOI value of PVC5 increased 5.6%, and its tensile strength also improved; the average heat‐release rate, average specific extinction area, and total smoke production of PVC5 decreased about 13.4, 28.0, and 48.8%, respectively. The char residue of PVC5 after CONE contained oxides and chlorides and was dense; this reduced the release of hydrogen chloride. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.
