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

Polimery 2005, No 9, 686



Summary

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.


Key words: polyurethane foam, polyurethane-polyisocyanurate foam, flame retardant, slow-burning polymers, red phosphorus, oxygen index
