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
heat 82 · fire 80
Aramid did not arrive as a finished commodity. DuPont 1965 Kwolek around United States still explains who makes it and which tests it sits in.

NIJ ballistic standards met para-aramid packs.
1990sAsbestos brakes
Aramid pulp in friction materials.
