ナイロン 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 ナイロン 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: ナイロン

ナイロン (PA6 / PA66) is a family of grades whose density ~1.14 g/cm³, heat band PA6 ~220 °C; PA66 ~260 °C, and fire letter combustible, melt-drip.

What “the material” actually is

ナイロン is sold as grades, not as a single substance. Chemistry PA6 / PA66, density ~1.14 g/cm³, heat band PA6 ~220 °C; PA66 ~260 °C.

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

Heat, fire and insulation

Conductivity note: low. Insulation score 30/100 is relative to 32 entries — metals lose, VIPs and aerogels win.

Fire letter in editorial use: combustible, melt-drip. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

How it is made and used

Origin: DuPont 1935–38, United States. The process chapter follows feedstock → conversion → forming → finish → install.

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

Market and circularity

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

Circularity mark 32/100. Ask which scrap, which certificate, which year.

よくある質問

Is ナイロン non-combustible?

Declared reaction class in this atlas: combustible, melt-drip. Assemblies still need resistance tests.

Does ナイロン insulate?

Thermal mark 30/100 versus the atlas. Conductivity note: low.

What is the density band?

~1.14 g/cm³

How is it made?

Origin story: DuPont 1935–38 (United States).

Can it be recycled?

Circularity mark 32/100 — editorial, route-specific.

Typical melting or failure heat?

PA6 ~220 °C; PA66 ~260 °C

What should it be paired with?

polyester: The cheaper filament that took shirts.

Where is it specified?

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