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

Scores compare 诺梅克斯 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.

Deep dive: 诺梅克斯

诺梅克斯 (poly(m-phenylene isophthalamide)) is a family of grades whose density ~1.38 g/cm³, heat band does not melt; decomposes ~400 °C+, and fire letter inherently FR textile.

What “the material” actually is

诺梅克斯 is sold as grades, not as a single substance. Chemistry poly(m-phenylene isophthalamide), density ~1.38 g/cm³, heat band does not melt; decomposes ~400 °C+.

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

Heat, fire and insulation

Conductivity note: low (fibre); papers electrically insulating. Insulation score 48/100 is relative to 32 entries — metals lose, VIPs and aerogels win.

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

How it is made and used

Origin: DuPont 1960s, United States. The process chapter follows feedstock → conversion → forming → finish → install.

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

Market and circularity

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

Circularity mark 36/100. Ask which scrap, which certificate, which year.

常见问题

Is 诺梅克斯 non-combustible?
Declared reaction class in this atlas: inherently FR textile. Assemblies still need resistance tests.
Does 诺梅克斯 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+
What should it be paired with?
aramid: The para-aramid strength cousin (Kevlar).
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
