Flammability, fire performance, and thermal stability of short glass fiber reinforced polyamide-6 and polyamide-66 containing halogenated and halogen-free flame retardants (FRs) were compared. Flammabilities were assessed by limiting oxygen index tests and UL94 classifications. Fire behavior was evaluated by mass loss cone calorimetry, a bench-scale tool, to assess fire performance of materials. Halogen-free, phosphorus-based FRs were shown to perform superior to halogenated counterparts on the basis of important fire properties, peak heat release rate, time to ignition, and fire growth index. Moreover, thermal stabilities were maintained at an acceptable level as a clear advantage of halogen-free FRs.


Corrosion Resistance Studies of Austenitic Stainless Steel Grades in Molten Zinc-Aluminum Alloy Galvanizing Bath
Loto, Roland Tolulope; Ozcan, Emre (Springer Science and Business Media LLC, 2016-06-01)
The corrosion inhibition performance and mechanical behavior of galvanized and heat-treated four newly developed austenitic stainless steel grades and type 316L austenitic stainless steel for application as sink rolls in galvanizing baths of 0.14-0.21 wt.% aluminum was investigated and compared through immersion corrosion test to determine the weight loss between 168 and 504 h, tensile test, and Charpy impact test. The delta ferrite content of the test samples was observed and estimated through optical micr...
Contribution of nanoclays to the flame retardancy of polyethylene-based cable insulation materials with aluminum hydroxide and zinc borate
Kaynak, Cevdet (SAGE Publications, 2014-03-01)
The main aim of this study was to investigate contribution of nanoclays to the flame retardancy of two cable insulation materials: low-density polyethylene and its blend with ethylene vinyl acetate. For this purpose, nanoclays were first incorporated alone, then together with traditional flame-retardant aluminum hydroxide, and then together with aluminum hydroxide-zinc borate system. Compounds and nanocomposites were prepared by melt mixing method with a twin-screw extruder, while specimens were shaped by c...
Usability of three boron compounds for enhancement of flame retardancy in polyethylene-based cable insulation materials
İBİBİKCAN, Esin; Kaynak, Cevdet (SAGE Publications, 2014-03-01)
It is known that for the production of halogen-free cable insulation materials based on polyethylene, very high amounts of traditional metal hydroxide flame retardants such as 65 wt% aluminum hydroxide are required to fulfill international directives. In this respect, the aim of this study was to reveal possible enhancement effects of three boron compounds on the flame retardancy of two cable insulation materials: low-density polyethylene and its blend with ethylene vinyl acetate both loaded with aluminum h...
Effects of nanoclays on the flammability of polystyrene with triphenyl phosphate-based flame retardants
Kaynak, Cevdet (SAGE Publications, 2013-07-01)
The main purpose of this study is to investigate the effects of nanoclays on the flammability behavior of neat polystyrene and polystyrene compounded with traditional flame retardants triphenyl phosphate and its synergist melamine cyanurate. Nanocomposites were prepared via ultrasound-assisted solution intercalation technique. Dispersion and nanomorphology of nanoclays were investigated through X-ray diffraction analysis and transmission electron microscopy. Thermal stability and flammability behaviors were...
Liquid steel flow in continuous casting machine: Modelling and measurement
Yavuz, Mehmet Metin (Informa UK Limited, 2011-08-01)
Single phase (liquid steel) and two-phase (liquid steel and argon bubbles) three-dimensional computational fluid dynamic and heat transfer models were developed for the continuous casting machines of ArcelorMittal. The computational domains include tundishes, slide gates, submerged entry nozzles and moulds. The effects of buoyancy, tundish design, tundish practices, nozzle design and caster practices on flow structure were investigated. Mathematical modelling is discussed in detail. In addition, submeniscus...
