Flame retardancy of poly(ethylene terephthalate), PET, was improved using different flame retardant additives such as triphenylphosphate, triphenylphosphine oxide, zinc borate, and boron phosphate (BP). Composites were prepared using a twin screw extruder and subsequently injection molded for characterization purposes. The flame retardancy of the composites was determined by the limiting oxygen index (LOI) test. Smoke emission during fire was also evaluated in terms of percent light transmittance. Thermal stability and tensile properties of PET-based composites were compared with PET through TGA and tensile test, respectively. The LOI of the flame retardant composites increased from 21% of neat PET, up to 36% with the addition of 5% BP and 5% triphenyl phosphate to the matrix. Regarding the smoke density analysis, BP was determined as an effective smoke suppressant for PET. Enhanced tensile properties were obtained for the flame retardant PET-based composites with respect to PET. (c) 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42016.

Mechanical, thermal, and fire retardant properties of poly(ethylene terephthalate) fiber containing zinc phosphinate and organo-modified clay DOĞAN, Mehmet; Erdogan, Selahattin; Bayramlı, Erdal (2013-05-01) The effect of zinc bisdiethylphosphinate (ZnPi) and organoclay on mechanical, thermal, and flame retardant properties of poly(ethylene terephthalate) (PET) fiber was investigated. ZnPi was preferred due to its fusible character at spinning temperature and organoclay was used for synergistic interaction. The mechanical, thermal, and flame retardant properties of fibers were examined by tensile testing, thermogravimetric analysis (TG), and micro combustion calorimeter (MCC). The tensile strength of the PET fi...
Synergistic fire retardancy of colemanite, a natural hydrated calcium borate, in high-impact polystyrene containing brominated epoxy and antimony oxide Kaynak, Cevdet (2011-05-01) This study explores for the first time the synergistic fire retardant action of natural hydrated calcium borate, namely the mineral colemanite, which partially replaces antimony oxide in brominated flame retardant high-impact polystyrene compounds. Various antimony oxide to hydrated calcium borate ratios were employed keeping the brominated flame retardant additive at a constant loading level. With partial colemanite substitution for antimony oxide, lower heat release rate, total heat evolved and fire growt...
FLAME RETARDATION AND MECHANICAL-PROPERTIES OF 1,3 PROPYLENE-GLYCOL BASED UNSATURATED POLYESTER Gündüz, Güngör; OZTURK, S (Informa UK Limited, 1994-01-01) Flame retardance properties of 1,3 propylene glycol based unsaturated polyester containing 40% styrene and 20% acrylonitrile were investigated. The polyester with 12% Br content is self-extinguishing while others with lower bromine contents burn slowly. The high decrease in mechanical strength due to the presence of bromine is highly compensated by acrylonitrile.
Hydrogen production over molybdenum loaded mesoporous carbon catalysts in microwave heated reactor system Guler, Melih; Doğu, Timur; VARIŞLI, DİLEK (2017-12-15) Ammonia decomposition reaction to produce COx free hydrogen over molybdenum incorporated mesoporous carbon based catalysts was studied in a microwave heated reactor system. Mesoporous carbon is acting as the catalyst support as well as the microwave receptor in the reaction medium. While the highest conversion value was 49% in conventionally heated reaction system at 600 degrees C, total conversion value was achieved over the same catalyst at 400 degrees C in microwave heated system with a GHSV of 36,000 ml...
Use of zinc borate as the third component of a traditional brominated flame retardant system in acrylonitrile butadiene styrene Kaynak, Cevdet (2013-11-01) Because zinc borate is an effective smoke suppressant and cheaper than antimony trioxide, the main aim of this study was to investigate usability of zinc borate as the third component of a traditional binary Br/Sb2O3 system in acrylonitrile butadiene styrene. Limiting oxygen index, UL-94, and mass loss cone calorimeter studies indicated that almost all flame retardancy parameters were kept when certain percentages of antimony trioxide were replaced with zinc borate. Residue analysis revealed that the predom...
