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
Prices are bands. A 2024 coil is not a 2026 contract. Labour and certification often dwarf the commodity.
Producers listed are landmarks for orientation, not a ranking or a procurement list.
