FLEXIBLE POLYURETHANE FOAM, PROCESS FOR PRODUCING THE SAME, AND AUTOMOTIVE SHEET EMPLOYING THE SAME

摘要

A novel flexible polyurethane foam which has satisfactory vibration characteristics and the excellent ability to maintain a passenger posture. The flexible polyurethane foam is obtained by reacting either a high-molecular polyoxyalkylene polyol or a polyol comprising the high-molecular polyoxyalkylene polyol and fine polymer particles dispersed therein with a polyisocyanate compound in the presence of a catalyst, a blowing agent, and a foam stabilizer, and is characterized in that the following fluorine compound (F) is used as at least part of the foam stabilizer in an amount of 0.00001 to 1 part by mass per 100 parts by mass of all active-hydrogen compounds. Fluorine compound (F): A compound which is a copolymer of (p) a fluoroacrylate or fluoromethacrylate with (q) an alkyl acrylate having a long-chain alkyl group, alkyl methacrylate having a long-chain alkyl group, acrylate having an oxyalkylene group, or methacrylate having an oxyalkylene group and optionally with (r) other copolymerizable monomer and which has a fluorine content of 12 to 50% by mass.
