Aramid is one of 32 materials in this atlas, grouped under textiles: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.

Scores compare Aramid with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.

Tiefe Einführung

Deep dive: Aramid

Aramid (PPTA (para) / meta-aramid cousin Nomex) is a family of grades whose density ~1.44 g/cm³, heat band does not melt; decomposes ~500 °C, and fire letter inherently FR vs commodity PA.

What “the material” actually is

Aramid is sold as grades, not as a single substance. Chemistry PPTA (para) / meta-aramid cousin Nomex, density ~1.44 g/cm³, heat band does not melt; decomposes ~500 °C.

This atlas treats Aramid as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

Conductivity note: low radial; fibre anisotropic. Insulation score 36/100 is relative to 32 entries — metals lose, VIPs and aerogels win.

Fire letter in editorial use: inherently FR vs commodity PA. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

How it is made and used

Origin: DuPont 1965 Kwolek, United States. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: nomex.

Market and circularity

Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.

Circularity mark 38/100. Ask which scrap, which certificate, which year.

Häufige Fragen

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

What should it be paired with?

nomex: The meta-aramid fire cousin.

Where is it specified?

Buildings, transport, energy and consumer goods — see the uses chapter.
