PURPOSE:To obtain the title foam excellent in thermoformability by reacting a specified active hydrogen compound with an active hydrogen compound comprising a compound which blocks NCO groups and an organic polyisocyanate in the presence of a blowing agent. CONSTITUTION:A process for producing a flexible polyurethane foam comprising reacting an active hydrogen compound (A) with an organic polyisocyanate (B) in the presence of a catalyst (C) and a blowing agent (D) and optionally other additives (E), wherein component A comprises an active hydrogen compound (a) having an average functionality of 2-6 and an average hydroxyl value of 20-200 and a compound (b) which blocks NCO groups at an (a)/(b) weight ratio of (99.5-80)/(0.5-20), is provided. This foam is excellent in comfortableness, sound-insulating performances, moldability, thermoformability, etc. and is useful for automotive interior furnishing materials, sound-insulating materials or pads for clothing. |
