<P>PROBLEM TO BE SOLVED: To provide a flexible polyurethane foam good in formability, wherein vibration transmission is reduced; and to provide a method for producing the same. <P>SOLUTION: The method for producing a flexible polyurethane foam by reacting an active hydrogen component (S) with an organic polyisocyanate component (B) in the presence of a foaming agent (C), a catalyst (D) and a foam stabilizer (E), is characterized in that the following polyol (s1) is contained in the (S) component. The polyol (s1) is a polyoxyalkylene polyol which is an alkylene oxide adduct of an active hydrogen-containing compound (H), wherein 40% or more of terminally positioned hydroxy groups are specific primary hydroxy group-containing groups; the hydroxyl value x, the total degree of unsaturation y and the ethylene oxide content z satisfy a specific relationship; the hydroxyl value is 10-50 mgKOH/g; and the ethylene oxide content is 4-25 wt.%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
