Abstract

Polyurethane flexible foams (PUFs) have a large market as upholstery and bedding cushioning material. There is an increasing demand for flame retarded grades in rail, plane and automotive transportation. Untreated PUFs are prone to rapid fire growth due to their low density and thermal conductivity. Furthermore, the low viscosity of the melt produced during combustion generates severe dripping with some foam compositions. This downward flow of flaming liquid can result in a pool fire that further enhances the rate of heat release. In this work we investigate the effect of clays, carbon nanofibers (CNFs) and polyhedral oligomeric silsesquioxane (POSS) on heat release rate and melt dripping of PUF based nanocomposites. It is shown that CNFs, can eliminate flaming liquid in a new small-scale flammability test.
