Production of PUR and PUR-PIR foams with red phosphorus as a flame retardant

W. Zatorski Z. K. Brzozowski K. Łebek

Abstract

Two kinds of foams: polyurethane (PUR) and polyurethane-polyisocyanurate (PUR-PIR) ones with red phosphorus as a flame retardant were prepared. As a blowing agent ozon friendly n-pentane with small amount of water was applied. The PUR-PIR foams showed better fire-resistance in comparison with PUR foams without deterioration of functional properties. Effect of synergism in lowering of flammability was obtained via the use of two chemical structures inhibiting the flammability: red phosphorus and isocyanurate rings.
