Nomex in 1970s: Fire service · 537
The behaviour of Nomex is written as 1970s’s “Fire service,” fixed by 400. An advert’s adjective is not a melting point. “Room temperature” alone is not a figure. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
DuPont’s meta-aramid — fire-fighter turnout, electrical paper and a char that does not melt-drip like nylon. Nomex 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 Nomex with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates. Nomex (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.
Nomex 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 Nomex as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: low (fibre); papers electrically insulating. Insulation score 48/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
“Fire service” for Nomex in 1970s carries 400. Praise without that figure is not a property.1970s
