Abstract: The flame retardancy of phosphorus- and halogen-containing flame retardants for rigid polyurethane foam was investigated by means of oxygen index tester and cone calorimeter. It showed that the flame retardancy of rigid polyurethane foam based on phosphorus-containing flame retardants was better than that on halogen-containing ones. Moreover, combinations the two kinds flame retardants provided even better results. For individual flame retardant, AK8803 was the most effective in extending the ignite time and reducing the heat damage, L580 was best one for inhibiting smoke and poison gas.

Key words: stabilizer, rigid polyurethane foam, flame retardancy
