Nomex in 1350: Nomex fibre IIIA
The behaviour of Nomex is written as 1350’s “Nomex fibre IIIA,” fixed by 400. An advert’s adjective is not a melting point. “Room temperature” alone is not a figure. CO, HCN, HF or fibres — the species depend on chemistry. Name the test (ISO 5659, EN 45545, NFPA 1971).
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. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
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+.
“Nomex fibre IIIA” for Nomex in 1350 carries 400. Praise without that figure is not a property.1350
