Claim 0:
1. A composite foam article comprising:
a polyurethane foam core presenting a first surface and a second surface facing opposite said first surface, said polyurethane foam core having a density of from 45 to 80 kg/m3, and having a compression force deflection at 10% deflection of from 10 to 110 psi when measured in accordance with ASTM 3574-D;
a first skin which is porous and disposed on said first surface, said first skin comprising a plurality of fibers, a polymeric binder, and a polyolefin powder in addition to said polymeric binder of said first skin;
a second skin which is porous and disposed on said second surface, said second skin comprising a plurality of fibers, a polymeric binder, and a polyolefin powder in addition to said polymeric binder of said second skin;
a first additional layer comprising an ethylene and acrylic acid (“EAA”) copolymer and disposed between said first surface of said polyurethane foam core and said first skin; and
a second additional layer comprising an EAA copolymer and disposed between said second surface of said polyurethane foam core and said second skin;
wherein said composite foam article has a post-compression thickness of from 1.5 to 5 mm and a strength of greater than 17 N at a post-compression thickness of greater than 2 mm when tested in accordance with SAE J949 at 23° C.
