Paper Details

Most of the domestic (interior decoration) and industrial systems use polyurethane (PU) based material.Flexible polyurethane foam (PUFF), a PU derivative is versatile because of its wide applications in many aspects and themain drawback of PUFF is its inflammability. The combustibility nature may end up with the fire hazard and accidents.The fire related accidents may be prevented by incorporating a suitable flame retardant (FR) in PUFF. The presence offlame retardants (FRs) mainly postpones the flashover which lessens the intensity of the burning rate. Brominatedhalogen based decabromodiphenyl ether (decaBDE) is selected as FR in this present study. decaBDE is incorporated asa FR to subsume the FR characteristics in PUFF in order to overcome the fire related accidents which is alarming incurrent condition. The composition of decaBDE was varied from 1 % to 5 % in order to assay the effect of added FR inthe laboratory based developed PUFF using polyol and isocyanate as the precursors. The effect of addition of decaBDEin PUFF was studied by analysing mechanical property (tensile strength, rebound resilience), physical property(density), thermal property (thermogravimetric analysis-TGA) and flammability test (UL 94). The cell structure(morphology) and the presence of functional groups in the developed PUFF were confirmed by using optical microscopeand Fourier Transform Infrared Spectroscopy (FTIR) respectively. The paper reports that the developed PUFF confirmsthe improved FR characteristics than the unmodified (without addition of FR) PUFF .
