Meta-aramida da DuPont: fardas de bombeiro, papel elétrico, carvão sem gotejamento.
Também chamado: meta-aramida · PMIA · Nomex paper
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.
Introdução profunda
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.
Origin: DuPont 1960s, United States. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: aramid.
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.
