Nomex in : Ageing
Read the condition on Nomex before the nickname. Year , line “Ageing,” figure 400. Euroclass is reaction. EI/R ratings are assemblies — boards, coats, cavities.
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. Circularity mark 36/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Nomex honest.
The para-aramid strength cousin (Kevlar). Coatings for steel vs fibres for people. The older inherently better-than-PE apparel fibre. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation. Declared performance after blowing-agent or moisture drift.
The label keeps Nomex, , and 400. “Ageing” is the condition on the figure.400
