In this polyurethane foam, the aromatic phosphate is added in the range of 200 to 1000 parts by weight with respect to 100 parts by weight of the total of polyisocyanate and polyol, and is said to be excellent in soundproofing and fireproofing properties (patent) Reference 1).

  Polyurethane foam in which a polyisocyanate, a polyol, a flame retardant, and a foaming agent are blended and a styrene polymer polyol is used as the polyol is considered to have excellent sound absorption characteristics and flame retardancy (Patent Document 2). .

  Furthermore, regarding the flame retardancy of polyurethane foam, a polyurethane foam in which polyisocyanate, polyol and foaming agent are blended and 3 to 25% by weight of tris (trihaloneopentyl) phosphate is also proposed. This polyurethane foam is said to be excellent in sound absorption and flame resistance (Patent Document 3).
