Abstract

There is described an isocyanate-based polymer foam having a V-0 rating according to Underwriters' Laboratories Standard 94 Flammability Test after aging of separate samples of the foam (i) for 168 hours at 150° C., and (ii) for 600 hours at 120° C. The foam may be in the form of a molded foam or a slabstock foam. The foam may be used in vehicular applications, such as an under hood application.
