Flexible polyurethane foam, process for its production, and seat for automobile using the flexible polyurethane foam

Abstract

To provide a flexible polyurethane foam having good vibration characteristics and suitable particularly for a seat for an automobile. A flexible polyurethane foam obtainable by reacting a polyol composition with a polyisocyanate compound in the presence of a catalyst, a blowing agent and a foam stabilizer, characterized in that the polyol composition comprises a high molecular weight polyoxyalkylene polyol (A1) and a polymer-dispersed polyol (A2) containing fine polymer particles in the high molecular weight polyoxyalkylene polyol (A1), and at least part of the fine polymer particles contained in the polymer-dispersed polyol (A2) are fine polymer particles having silicon atoms.
