Nanoclay Flame Retardancy: Why a Few Percent of Clay Can Change a Polymer's Fire Behaviour

In 1993, researchers at Toyota’s research laboratory published results showing that nylon 6 containing 4.7% montmorillonite had a heat release rate roughly half that of unfilled nylon under cone calorimeter testing conditions. This was one of the first demonstrations that a very small amount of nanoclay could substantially change polymer fire behaviour — and it launched a research field that has since generated thousands of publications and several commercial applications.
