摘要: Flame retardant polyurethane foams are produced by mixing and reacting a polyol, low molecular weight compound with 1 or more active hydrogen, an organic polyisocyanate acidic boron in the presence of organo-metal urethane catalyst. The flame-retardant foam may be used for thermal sound insulation, cushioning molding useful objects.
