Abstract: A flame-resistant and sound- and vibration-insulating member for a vehicle, which is a soft polyurethane foam formed by a reaction between an organic polyisocyanate component and a polyol component, wherein the organic polyisocyanate component includes as a major component a monomeric MDI and further includes a reaction product containing carbodiimide and/or uretone imine groups, the monomeric MDI containing 29-33% of NCO and including 1-45% by weight of 2,4′-diphenylmethane diisocyanate, while the polyol component includes at least 50% by weight of polyol having 2-8 functional groups and a molecular weight of 1000-10000, and wherein the soft polyurethane foam has a density of 40-150 kg/m3, a 50% compressive load of (5-60)×10−2N/mm2, a tensile strength of at least 120 kPa and an elongation of at least 50%, and exhibits flame resistance according to FMVSS-302. A process of manufacturing the flame-resistant and sound- and vibration-insulating member is also disclosed.

Abstract: A noise insulating member having a low degree of water absorbency and a low degree of oil absorbency. The noise insulating member includes a polyurethane foam obtained by reaction of an organic polyisocyanate component and a polyol component in the presence of a fluorine-containing surfactant, and having a cellular network having cells and communication holes which communicate with said cells. The communication holes have respective diameters each of which is not larger than 60 &mgr;m.

Abstract: A soft polyurethane foam which has a rebound resilience percentage of not higher than 30% and whose temperature dependency of a compression force deflection that is represented by a difference between a 25%-compression force deflection value at -20.degree. C. and a 25%-compression force deflection value at +20.degree. C. is not larger than 0.030 kg/cm.sup.2.

Abstract: A method and a foamed resin molding in which a skin layer is formed by pressing an expansible film against and into conformity with cavity walls of a mold or a bag-like cover member by foaming pressure of a foamable resin and a foamed resin body molded concurrently and integrally under the skin layer, which facilitate the easy parting of the moldings from the mold without parting agent.
