Abstract: A laminate product particularly useful in vehicular applications is described. The laminate product comprises a foam core having a first major surface and a second major surface. One or both of the major surfaces comprises a fibrous layer and an adhesive layer adhering the fibrous layer to the foam core. The process for producing the laminate product involves exposing an initial laminate product to infrared radiation. A portion of the adhesive layer between fibers in fibrous layer being ablated. The foam laminate product has improved sound absorption properties and while maintaining desirable strength and stiffness properties. In addition, in certain cases, the peel strength of the fibrous reinforcing layer to the foam core is significantly improved in the present foam laminate product compared to the conventional approaches.

Abstract: In one of its aspects, the present invention relates to foamed isocyanate-based polymer derived from a reaction mixture comprising an isocyanate, an active hydrogen-containing compound, a dendritic macromolecule and a blowing agent; wherein at least a 15% by weight of the dendritic macromolecule may be mixed with a polyether polyol having an OH number less than about 40 mg KOH/g to form a stable liquid at 23° C. The dendritic macromolecule confers advantageous load building characteristics to the foamed isocyanate-based polymer and may be used to partially or fully displace the use of conventional copolymer polyols used. A process for production of a foam isocyanate-based polymer and a process for conferring loading building properties to a foamed isocyanate-based polymer are also described.
