A flexible isocyanate-based polymeric foam which has: (i) low resiliency; (ii) a Tg less than or equal to about 0&deg; 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 &minus;20&deg; to about &plus;60&deg; 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&mdash;e.g., &minus;20&deg; to &plus;60&deg; C.

Isocyanate-based polymer foam and process for production thereof

A one-part moisture curable polyurethane adhesive composition comprises a blend of polyurethane prepolymers and one or more additives which unexpectedly improve the sag resistance and mechanical properties of the formulation. The final adhesive composition retains good stability in the absence of moisture for an extended period between manufacture and application of the adhesive, and has a relatively rapid and consistent cure rate in the presence of atmospheric moisture. The final cured composition exhibits good mechanical properties and generally is unaffected by ambient application and cure conditions.
