Abstract: The present disclosure provides for an isocyanate-reactive composition that can react with an isocyanate compound in a reaction mixture to form a polyurethane-based foam. The isocyanate-reactive composition includes an isocyanate reactive compound and a combustion modifier composition. The isocyanate reactive compound has an isocyanate reactive moiety and an aromatic moiety. The combustion modifier composition includes both phosphorus from a halogen-free flame-retardant compound and a transition metal from a transition metal compound. The combustion modifier composition can have a molar ratio of the transition metal to phosphorus (mole transition metal:mole phosphorous) of 0.05:1 to 5:1.
