摘要: A prepolymer composition for preparing polyurethane insulating foams with fire-retardant properties from pressurized containers consists of a component at least one containing 4 - 20 % by weight NCO groups, and usual additives, as well propellant gas. The is essentially halogen-free has 5 to 40 weight, based on the component, plasticizing phosphates and/or formulas O = P (OR)3 (OR)2R.
