Abstract: A flexible isocyanate-based polymeric foam which has: (i) low resiliency; (ii) a Tg less than or equal to about 0° C.; and (iii) a change in tan &dgr; less than or equal to about 35% from a median value measured over a temperature range of from about −20° to about +60° C. The foam may be produced using a formulation comprising selected plasticizers as set in the disclosure. The subject foam is less temperature sensitive than currently known low resilience, flexible polyurethane foams. Thus, the present foam finds many applications such as for use in the interior of a vehicle where energy dissipation of the foam is important over a relatively wide temperature range—e.g., −20° to +60° C.
