Abstract: Melamine and dimethyl methyl phosphate (DMMP) was used as flame retardants for rigid polyurethane foams. The effects of isocyanate index, the amounts of water, melamine, and DMMP on the flame retardant performance and tensile strength of the foams were studied. It was found that when the contents of melamine and DMMP were 25 parts each, water content was 1.5 parts, isocyanate index was 1.15, the foams provided the optimal comprehensive performance.

Key words: rigid polyurethane foam, tensile property, flame retardancy, melamine, dimethyl methyl phosphate
