Quick answers

Is Nomex non-combustible?

Declared reaction class in this atlas: inherently FR textile. Assemblies still need resistance tests.

Does Nomex insulate?

Thermal mark 48/100 versus the atlas. Conductivity note: low (fibre); papers electrically insulating.

What is the density band?

~1.38 g/cm³

How is it made?

Origin story: DuPont 1960s (United States).

Can it be recycled?

Circularity mark 36/100 — editorial, route-specific.

Typical melting or failure heat?

does not melt; decomposes ~400 °C+

heat 88 · fire 94
