Abstract: There is described an isocyanate-based polymer foam having the combination of: (i) a Limiting Oxygen Index (LOI) of greater than or equal to 26.5% when measured pursuant to ASTM D2863-17a, and (ii) a Total Volatile Organic Content (TVOC) when measured pursuant to VDA 277 of less than or equal to 225 μg/g C. Preferably, the foam is produced from a foamable composition comprising: an isocyanate; a reactive compound containing: (1) at least one hydrogen which is reactive with the isocyanate, and (2) one or both of a halogen and a phosphate moiety; a blowing agent comprising one or both of water and carbon dioxide; and a catalyst; wherein the reactive compound is present in an amount in the range of from about 30% to about 95% of total ISO equivalents excluding water, if present in the foamable composition.
