Smoldering is a self-sustaining heterogeneous oxidation reaction that induces a slow, low temperature, flameless combustion.1 Flexible polyurethane foams (PUF) are particularly prone to smoldering due to their high air permeability and low density. In this study we investigate the effect of PUF cell structure and morphology on smoldering. Our preliminary results show that above a threshold value of air permeability, the specific surface area of PUF might be used to assess smoldering.
