- Abstract
Glass fiber reinforced polyamide ( PA) 6 T/ DT flame retarded with aluminum diethylphosphinate ( AlPi) was tested to assess its flame retardant properties. Models for the decomposition of PA 6T/ DT with and without AlPi are presented. Thermal decomposition was measured by performing TGA with Fourier transform infrared ( FTIR) spectroscopy and FTIR spectroscopy in the condensed phase. Fire behavior was studied using a cone calorimeter and flammability was tested with UL 94 and the limiting oxygen index. AlPi works as an effective flame retardant for glass fiber reinforced PA 6T/ DT materials, acting in the gas phase. Also observed was condensed-phase action, which occurs especially under oxidative conditions before the samples ignite. © 2013 Society of Chemical Industry
