Summary: | The present invention relates to a reactive formulation used to make a flame resistant flexible polyurethane foam which is particularly suited for use in under the hood vehicle applications which require sound deadening and vibration management and a process to make said foam. Said foam is particularly suitable for such applications because desirable flame resistant properties are achieved after exposure to heat over an extended period of time. In particular, the flame resistant flexible polyurethane foam is made from a reactive formulation comprising an A side comprising (i) one or more organic isocyanate and a B side comprising (ii) one or more isocyanate-reactive component, (iii) a flame retardant component comprising a combination of red phosphorus, expandable graphite, and optionally sodium citrate wherein the flame retardant component does not contain ammonium polyphosphate; and (iv) one or more additional component selected from a catalyst, a blowing agent, a cell opener, a surfactant, a crosslinker, a |
