Nomex in 1970s: Nomex paper
Read the condition on Nomex before the nickname. Year 1970s, line “Nomex paper,” figure 400. Declared performance after blowing-agent or moisture drift. A material is what it is made of, the condition it survives, and where it goes afterward. Nomex under “Nomex paper” in 1970s should say which, with 400 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
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. The zone where heat or chemistry changes the datasheet.
The label keeps Nomex, 1970s, and 400. “Nomex paper” is the condition on the figure.1970s
