<P>PROBLEM TO BE SOLVED: To provide a method for producing a flexible polyurethane foam having high mechanical properties and excellent vibration characteristics. <P>SOLUTION: The method for production of a flexible polyurethane foam includes reacting a polyol component (A) with an organic polyisocyanate component (B) in the presence of a catalyst (C), a foaming agent (D) and a foam stabilizer (E). The polyol component (A) contains: a strength-improving agent (A1) shown by a specific structural formula; and a polyoxyethylene-polyoxypropylene polyol (A2) in which a number-average functional group number is 3 to 4, a hydroxyl value is 5-50 mg-KOH/g, and the content of terminal oxyethylene units is 10-30 wt.%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
