PROBLEM TO BE SOLVED: To provide a polyurethane foam good in heat resistance, moist heat resistance fire retardancy.SOLUTION: In a polyurethane foam obtained from a polyurethane foaming raw material including polyol, polyisocyanate, a foaming agent, a catalyst and a fire retardant, the polyol includes polyester polyol having the side chains of an alkyl group by one or more, the polyisocyanate is made of diphenylmethane diisocyanate, the fore retardant is made of either or both of powder fire retardants selected from expanded graphite and a phosphorous-based powder fire retardant, the addition amount thereof is 20 to 40 pts.mass to 100 pts.mass of the polyol and the density of the polyurethane foam (JIS K7222:2005) being 80 to 120 kg/m.SELECTED DRAWING: None

    【課題】耐熱性、耐湿熱性及び難燃性が良好なポリウレタンフォームの提供を目的とする。【解決手段】ポリオール、ポリイソシアネート、発泡剤、触媒及び難燃剤を含むポリウレタン発泡原料から得られるポリウレタンフォームにおいて、ポリオールは、アルキル基の側鎖を1以上持つポリエステルポリオールを含み、ポリイソシアネートは、ジフェニルメタンジイソシアネート系イソシアネート、難燃剤は、膨張黒鉛またはリン系粉体難燃剤の何れか一方又は両方の粉体難燃剤からなり、添加量が前記ポリオール100質量部に対して20〜40質量部で、ポリウレタンフォームの密度(JIS K7222:2005)が、80〜120kg/m3である。【選択図】なし
