Abstract

To provide a polyol-containing composition that can achieve quasi-incombustibility without using a powder fire retardant, and an expandable polyurethane composition using the polyol-containing composition.SOLUTION: A polyol-containing composition is intended to obtain polyurethane foam by being reacted with polyisocyanate, and contains polyol, a blowing agent, a fire retardant, and a catalyst. Phosphorus concentration in the polyol-containing composition is 3 mass% or more in the polyol-containing composition.SELECTED DRAWING: None
