Nomex in 1970s: Fire service
Read the condition on Nomex before the nickname. Year 1970s, line “Fire service,” figure 400. Circularity mark 36/100. Ask which scrap, which certificate, which year.
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+.
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 letter in editorial use: inherently FR textile. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
The label keeps Nomex, 1970s, and 400. “Fire service” is the condition on the figure.1970s
