Novel Clay-Based Coating May Point the Way to New Generation of Green Flame Retardants

Caption: Using a testing device called a cone calorimeter, NIST researchers measure the heat-release rate and other flammability properties of materials. Above, untreated polyurethane foam catches fire from a nearby heat source. Below, foam treated with a novel clay-filled coating did not ignite when exposed to the same heat source. Instead, a fast-growing protective layer -- called char -- forms on the surface.
