Thermally resistant polyurethane foams with reduced flammability
View through CrossRef
Thermally resistant polyurethane foams containing 1,3,5-triazine ring were modified with additive flame retardants. It has been found that addition of melamine, melamine polyphosphate, or isocyanurate at the foaming step resulted in reduction of foam flammability. The physical properties of flame-retardant modified foams were compared with those of non-modified foams. The obtained modified foams showed oxygen index 22.2–24.2 and were highly thermally resistant even at long lasting 200℃ temperature exposure.
