Quick answers
Is Aramid non-combustible?
Declared reaction class in this atlas: inherently FR vs commodity PA. Assemblies still need resistance tests.
Does Aramid insulate?
Thermal mark 36/100 versus the atlas. Conductivity note: low radial; fibre anisotropic.
What is the density band?
~1.44 g/cm³
How is it made?
Origin story: DuPont 1965 Kwolek (United States).
Can it be recycled?
Circularity mark 38/100 — editorial, route-specific.
Typical melting or failure heat?
does not melt; decomposes ~500 °C

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.

Resource belts
Ore, plantations or energy that feed primary routes.
Global trade
Aramid moves as coils, bales, boards or chemicals — check HS codes, not vibes.
