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.

Abstract: A composite foam article comprises a foam core layer presenting a first surface and a second surface facing opposite the first surface. A first polymeric bonding layer is disposed on the first surface, one or more first reinforcing layers comprising a plurality of fibers and a polymeric binder are disposed on the first polymeric bonding layer, and a first polymeric containment layer is disposed on the one or more first reinforcing layers. A second polymeric bonding layer is disposed on the second surface, one or more second reinforcing layers comprising a plurality of fibers and a polymeric binder are disposed on the second polymeric bonding layer, and a second polymeric containment layer is disposed on the one or more second reinforcing layers. At least one catch layer comprising particles of carbon is dispersed in and/or disposed between any of the aforementioned layers.
