“…A similar study was reported recently for poly(ethylene terephthalate), proving the condensed phase action of such systems [34]. It was reported that presence of a metal oxide stabilizes the intermediate pyrolysis products, promoting cross-linking reactions between the polymer chains.…”

Abstract:The latest techniques used to prove, describe and analyze the gas phase activity of a fire retardant used in polymeric materials are briefly reviewed. Classical techniques, such as thermogravimetric analysis or microscale combustion calorimetry, as well as complex and advanced analytical techniques, such as modified microscale combustion calorimeter (MCC), molecular beam mass spectroscopy and vacuum ultra violet (VUV) photoionization spectroscopy coupled with time of flight MS (TOF-MS), are described in this review. The recent advances in analytical techniques help not only in determining the gas phase activity of the flame-retardants but also identify possible reactive species responsible for gas phase flame inhibition. The complete understanding of the decomposition pathways and the flame retardant activity of a flame retardant system is essential for the development of new eco-friendly-tailored flame retardant molecules with high flame retardant efficiency.

“…On the other hand, antimony oxide (Sb 2 O 3 ) with a wide band gap of 3.4 eV, has also being used in various applications as catalyst [21], flame retardant [22][23][24], optoelectronic and photoelectric devices [25][26][27]. The photocatalytic activity of pure Sb 2 O 3 is low due to high band gap (E g =3.4 eV) [28].…”

“…But the aromatic ring or polyaromatics (1600 cm -1 ) structure still existed in the residue. The absorption bands of aluminum phosphate derivatives (orthophosphate, pyrophosphate) (1119,1107 cm -1 ) were detected [8], giving positive evidence that the phosphorus component in composites had changed its structure in the char layer when the temperature reached 500°C (Table 6).…”

“…It has been reported that UPR can be modified with ammonium polyphosphate, melamine pyrophosphate [5], red phosphorus [6] and DOPO ramification [7] to enhance their flame retardancy. As a novel chemical group of phosphorous flame retardants, metal phosphinates show a strong flame retardant activity not only on their own but also a pronounced synergism with selected nitrogen-containing organic substances or metal oxides [8], which has been widely used in PET, PA6, PA66 and EP [9][10][11].…”

The synergistic flame retardant effects of AlPi and ATH in UPR were investigated. The flammability and thermal stability of UPR composites were evaluated with LOI, UL-94 vertical burning, MCC and TG. The structure and morphology of filler and char residues were examined with SEM and FTIR. The interaction between AlPi and ATH was observed when the mass ratio of AlPi and ATH was 3:2 and LOI value of flame-retarded UPR increased to 30 and UL-94 rating passed V-0; however, the SEM showed that AlPi and ATH have a good dispersion in UPR. The pHRR of UPR-15AlPi/10ATH was 241.6 Wg -1 , decreasing by 30.4 % compared with pure UPR. The experimental TG curve of AlPi/ATH in N 2 was lower than calculated one at the second stage and had lower char residue at 700°C, demonstrating interaction of AlPi and ATH during thermal degradation. The char residue of UPR-15AlPi/10ATH at 700°suggested that the interaction between AlPi and ATH strengthened the char-formation ability and thermal stability of UPR, so the SEM showed a strong and dense char surface. The FTIR of char residues at different temperatures showed that AlPi and ATH interactions changed the type of aluminum phosphates, making char residue of UPR/AlPi/ATH system increased eventually.
