Based on the study of the burning mechanism of the rigid polyurethane foam, the article claims that the fire resistance of the foam can be greatly improved by changing the burning course and heightening the initial combustion temperature. Combined fire resistant with fine insulating property and physical performance as well as fine flame retardant property has been developed.
