It is an object of the present invention to provide a method for producing a vehicle seat pad that is difficult to diffuse aldehyde with good curability. In the present invention, an active hydrogen component (A) and an organic polyisocyanate (B) are reacted in the presence of a foaming agent (C), a urethanization catalyst (D), a foam stabilizer (E), and an additive (F). A method for producing a vehicle seat pad comprising the step (I) of obtaining a flexible polyurethane foam, wherein (C) contains water and (F) is a urea compound represented by the following general formula (1) ( F1), containing at least one selected from the group consisting of amino acids (F2) and polyphenols (F3), the core density of the flexible polyurethane foam is 25 to 90 kg / m 3 , and the resilience is 50 to 75%. It is a manufacturing method of the pad for vehicle seat sheets whose hardness (25% -ILD) is 150-400 N / cm < 2 >. |
