This article addresses the flame retardancy of polyurea using three different sulfonate salts, sodium diphenylamine-4-sulfonate, 3-(1-pyridinio)-1-propane sulfonate, and ammonium sulfamate, and their combination with some conventional flame retardants. Cone calorimetry and thermogravimetry are used for the evaluation of the flame retardancy and thermal stability. Among the sulfonate salts, ammonium sulfamate shows the best flame retardancy both alone and in combination. The conventional… CONTINUE READING
