The effectiveness of potassium aluminum sulphate (alum) as flame retardant was studied by incorporating varying concentrations of it: 0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% in the foam recipes. Fire characteristics of the foam samples produced were investigated and the results compared with the control. Results of the investigation showed that as the concentration of potassium aluminum sulphate increases, the ignition time, add-on, and char formation increases while the flame propagation rate and afterglow time decreases. Thermal behavior of the foam samples were also determined using thermo gravimetric analyzer. Results show that the novel flame retardant in the foam samples delayed the onset of degradation time and also high activation energy was required for the burning of the foam samples
