Abstract: An object of the present invention is to provide a polyurethane composition, in which reduction in the strength of the foam is suppressed when the foam has been greatly deformed. The present invention relates to a polyurethane composition comprising a base resin and a curing agent, wherein the base resin comprises a compound (A-1) comprising a polyalkylene skeleton comprising neither an aromatic skeleton nor an alicyclic skeleton, and having two or more functional groups having an active hydrogen atom, a compound (A-2) comprising an aromatic skeleton and/or alicyclic skeleton, and having two or more functional groups having an active hydrogen atom, a blowing agent (B), and an amine-based catalyst (C); a polyurethane foam therefrom; and a method for soundproofing and reinforcing a vehicle.
