    Abstract: There is described a foamed isocyanate-based polymer derived from a reaction mixture comprising: an isocyanate; a polyol composition comprising a first prescribed amount of polymer particles dispersed in a base polyol; a second prescribed amount of biomass-based carbonaceous particulate material; and a blowing agent. In one embodiment, the foamed isocyanate-based polymer having an Indentation Force Deflection when measured pursuant to ASTM D3574-11 which is within about 15% as that of a reference foam produced by omitting the biomass-based carbonaceous particulate material from the reaction mixture and increasing the amount of polymer particles in the polymer polyol composition to equal the sum of the first prescribed amount and the second prescribed amount. In another embodiment, the foamed polymer has a cellular matrix comprising a plurality of interconnected struts, the biomass-based carbonaceous particulate material conferring to the cellular matrix a load efficiency of at least about 5 Newtons/weight % of biomass-based carbonaceous particulate material. A process to produce the foamed isocyanate-based polymer is also described. A polyol-based dispersion to produce the foamed isocyanate-based polymer is also described. It has been discovered that a relatively expensive petroleum-based copolymer polyol can be fully substituted by a relative inexpensive bio-based (amorphous carbon) dispersion with no significant compromise in important physical properties in the resulting polyurethane foam.

    Abstract: There is described a foam article comprising: a base foam having a textured surface; a trim cover covering at least a portion of the textured surface, the trim cover comprising: (i) a finished outer layer comprising an occupant-contact outer portion and inner portion; (ii) a compressible buffer layer secured with respect to the inner portion of the finished outer layer; and (iii) a contact layer secured with respect to the compressible layer and configured to be in contact with the textured surface of the base foam, the contact layer having a secant modulus at 5% strain of at least about 7 when measured according to modified ASTM D3574-11, Test E, Tensile Test. There is also described a foam article comprising: a base foam having a textured surface; a trim cover comprising a finished outer layer; and optionally, a contact layer interposed between the foam element and the trim cover, the contact layer in contact with at least a portion of the textured surface of the base foam and comprising a contact material; the foam article having a read through score of at least 20 when measured pursuant to modified ASTM D3575-11 I2 (Procedure B). The present inventors have discovered that the occurrence of “read through” may be obviated or mitigated if the contact layer having a secant modulus at 5% strain of at least about 7 when measured according to modified ASTM D3574-11, Test E, Tensile Test is used.

    Abstract: A laminate product comprising a foam core having a pair of opposed major surfaces and a cover layer secured with respect to each major surface is described. The cover layer contains a fibrous reinforcement layer that is substantially encapsulated by a polymer. It has been found that the use of a fibrous polymer layer (e.g., in place of conventional polyethylene film) results in a laminate product having significantly lower resistance to air flow resistance and significantly improved sound absorption properties.

    Abstract: In a preferred embodiment there is disclosed a vehicular seat element comprising a foam substrate, the foam substrate comprising an A-surface for contact by an occupant and a B-surface opposed to the A-surface, a central portion of the A-surface have a first surface area and comprising a plurality of channels, the central portion of the A-surface comprising an occupant contact portion having a second surface area, wherein the first surface area is greater than the second surface area, a plurality of apertures disposed in the plurality of channels, each aperture interconnecting the A-surface and the B-surface of the foam substrate. The plurality of channels acts a distribution manifold for air to be moved laterally with respect to the A-surface of the foam pad and also through the holes in the seat pad to allow for circulation of air. In other words, the through holes in the foam provide a pass for air to flow from the B-surface of the foam pad to the A-surface of the foam pad, and vice versa. This air flow is further promoted by compressing and decompressing of the foam by the mass of the occupant while the vehicle is in motion. This compression and decompression of the foam creates a so-called bellows effect to push or pull air through the vehicular seat. Ideally, the series of channels molded in the A-surface of the foam pad form a manifold that enhances air distribution by providing multiple paths for the air flow around (not just beneath) the occupant and through the seat.

    Abstract: The invention relates mold, particularly a mold for producing foam articles. In a preferred embodiment, the mold comprises a lid and a bowl releasingly engageable to define a mold cavity, the lid comprising: (i) a vent having a passageway for gas to escape from the mold cavity, and (ii) a plurality of grooves connected to the vent. The use of a plurality of grooves/slots in the mold cavity surface effectively acts as a siphon to draw gas away from the composition to be molded. The plurality of grooves/slots is connected to one or more vents which then allows for escape of the gas from the mold cavity to the exterior of the mold.
