Use of zinc borate as the third component of a traditional brominated flame retardant system in acrylonitrile butadiene styrene

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 predominant flame retardancy mechanism of the traditional system was gas phase action, whereas zinc borate contributes especially in the condensed phase action by forming thicker and stronger char layer.

Use of boron oxide and boric acid to improve flame retardancy of an organophosphorus compound in neat and fiber reinforced polyamide-6
POLAT, Osman; Kaynak, Cevdet (2016-09-01)
The aim of this study was to investigate the usability of boron oxide and boric acid to enhance flame retardancy of (aluminum diethyl phosphinate)-type organophosphorus compound in polyamide-6 and its 15 wt% of short (glass fiber)-reinforced composite. Materials were compounded by melt-mixing method via a twin-screw extruder, and the specimens for testing and analyses were shaped by injection and compression-molding. For the neat polyamide-6 specimens, mass loss cone calorimetry analyses indicated that repl...
The role of nanoparticle geometry in flame retardancy of polylactide nanocomposites containing aluminium phosphinate
Isitman, Nihat Ali; Doğan, Mehmet Onur; BAYRAMLI, ERDAL; Kaynak, Cevdet (2012-08-01)
Although there is considerable research effort in the development of halogen-free flame-retardant polylactide (PLA), a bio-based aliphatic polyester, the potential synergistic interactions of nanoparticles and conventional additives have scarcely been considered. Therefore, this study aimed to investigate the influence of nanofiller geometry on fire retardancy of PLA nanocomposites containing aluminium diethylphosphinate (AlPi) flame retardant. For this purpose, a variety of nanofiller geometries were utili...
Nanoclay and carbon nanotubes as potential synergists of an organophosphorus flame-retardant in poly(methyl methacrylate)
Isitman, Nihat Ali; Kaynak, Cevdet (2010-09-01)
This study explores whether nanoparticles incorporated in polymers always act as synergists of conventional flame-retardant additives. For this purpose, two different filler nanoparticles, namely organically modified layered-silicate clay minerals or nanoclays and multi-walled carbon nanotubes, were incorporated in poly(methyl methacrylate) filled with an organophosphorus flame-retardant that acts through intumescence. Effective dispersion techniques specific to each nanoparticle were utilized and prepared ...
Influence of zinc borate on flame retardant and thermal properties of polyurethane elastomer composites containing huntite-hydromagnesite mineral
Dike, Ali Sinan; Tayfun, Umit; DOĞAN, Mehmet (2017-11-01)
The effect of zinc borate (ZnB) was studied on the flame retardant and thermal properties of thermoplastic polyurethane containing huntite-hydromagnesite. The flame retardant properties of thermoplastic polyurethane-based composites were investigated using limiting oxygen index, vertical burning test (UL 94), thermogravimetric analysis, and mass loss calorimeter. No remarkable effect of ZnB was observed on the flammability properties of composites. UL 94 rating did not change regardless of the added amount ...
Effect of boron containing materials on flammability and thermal degradation of polyamide-6 composites containing melamine cyanurate
Yılmaz, Ayşen; Bayramli, Erdal (2011-05-01)
Three different boron containing materials, zinc borate (ZnB), borophosphate (BPO(4)), and boron and silicon containing oligomer (BSi), were used to improve the flame retardancy of melamine cyanurate (MC) in a polyamide-6 (PA-6) matrix. The combustion and thermal degradation characteristics were investigated using limiting oxygen index (LOI), UL-94 standard, thermogravimetric analysis-Fourier transform infrared spectroscopy (TGA-FTIR), differential scanning calorimeter (DSC), and scanning electron microscop...
