Nanoclay as a Flame Retardant: How It Works and Where It Fits

Mon, 13 Apr 2026 00:00:00 +0000

Flame retardancy is one of the most commercially important applications of nanoclay in polymer composites — and one of the most misunderstood. The misunderstanding usually starts with the data. Cone calorimeter results for nanoclay nanocomposites show dramatic reductions in peak heat release rate (sometimes 50–70%), which looks like excellent fire performance. Then someone tests flammability by UL-94 and finds the nanoclay doesn’t help at all, or barely passes. Confusion follows.
