| 20110230577 | ISOCYANATE-BASED FOAM HAVING IMPROVED ANTI-YELLOWING PROPERTIES AND PROCESS FOR PRODUCTION THEREOF - There is described an isocyanate-based polymer foam having improved anti-yellowing properties. The foam produced from a formulation comprising an isocyanate, a blowing agent, a first active hydrogen-containing compound and a second active hydrogen-containing compound different than the first active hydrogen-containing compound. The second active hydrogen-containing compound comprises an active hydrogen-containing phosphite compound. A process for producing such a foam is also described. | 09-22-2011 |
| 20110020483 | VENTED MOLD AND METHOD FOR PRODUCING MOLDED ARTICLE - 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. | 01-27-2011 |
| 20100255242 | PROCESS FOR ADHERING FOAM ELEMENTS AND PRODUCT THEREOF - There is described a process for adhering a first elongate foam element having a first end portion to a second elongate foam element having a second end portion. The process comprises an initial step of melting a first surface portion of the first end portion to produce a first molten portion. Next the first end portion is abutted to the second end portion. Thereafter, the first molten portion is caused to solidify to create a seam bond between the first end portion and the second end portion. Thus, the present invention relates to adhering two elongate foam elements together at their end portions. The bond between the foam elements is created by melting at least a portion of the surface of one or both of the end portions of the two foam buns. This creates insitu a molten region which acts as an adhesive when the end portions of the two buns are abutted or otherwise contacted with each other. | 10-07-2010 |
| 20100060066 | VEHICULAR SEAT SYSTEM AND VEHICULAR HEADREST - The invention relates to a vehicular seat system including a seat bottom and a seat back. The headrest is connected to the seat back. The headrest consists of a number of components. These components include: a non-foam frame element, a non-foam insert secured with respect to a portion of the frame element, and a resilient element in which at least a portion of the frame element and the entire insert are embedded. The resilient element consists essentially of a homogeneous foam material. The frame element comprises a pair of post elements for coupling to the vehicular seat back. The post elements are interconnected by a cross-piece element. The headrest is connected to the seat back such that the minimum distance between the outer surface of the headrest for contacting a head of an occupant and the insert is in the range of from about 10 mm to about 30 mm. The vehicular headrest useful in the present seat system is compliant with the FMVSS 202a backset retention requirement | 03-11-2010 |
