The fire‐retardant effectiveness of mixtures of hexabromocyclododecane (HBCD) and artimony oxide (Sb 2 O 3 ) in polyethylene (PE) was examined utilizing differential thermal analysis (DTA), gas chromatography/mass spectroscopy (GC/MS) and limited oxygen index (LOI) techniques. It was determined that the normal practice of mixing Sb 2 O 3 with HBCD induced a synergistic chemical reaction at 250°C whose main product, SbBr 3 , was responsible for enhanced fire retardancy. The mixing of SbBr 3 directly into the PE produces a superior fire‐retardant polyethylene.
