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.

Isocyanate-based polymer foam having improved flame retardant properties

There is described a process for producing a free-rise polyurethane foam having a density of less than or equal to about 0.75 pcf. the process comprises the steps of: (a) contacting: (i) an isocyanate, (ii) a first polyol comprising a first polymer chain consisting essentially of propylene oxide units and alkylene oxide units selected from ethylene oxide, butylene oxide and mixtures thereof in a weight ratio of propylene oxide units to alkylene oxide units in the range of from about 90:10 to about 25:75, the polymer chain being terminally capped with the ethylene oxide units, the first polyol having a primary hydroxyl content of at least about 70% based on the total hydroxyl content of the first polyol, (iii) water (iv) a surfactant and (v) a catalyst to form a foamable reaction mixture; and (b) expanding the foamable reaction mixture to produce the free-rise polyurethane foam.

Process for producing a low density free-rise polyurethane foam

A composite foam article is disclosed herein. The composite foam article comprises a polyurethane foam core presenting a first surface and a second surface facing opposite the first surface. A first skin is disposed on the first surface and a second skin is disposed on the second surface. The first and second skins comprise a plurality of fibers and a polymeric binder. The composite foam article also comprises at least one supplemental layer comprising an ethylene and acrylic acid copolymer dispersed in and/or disposed between any of said aforementioned skins and core.
