Aramid in : Defects
Read the condition on Aramid before the nickname. Year , line “Defects,” figure 500. Indentation, drape or compressive class — whichever the trade actually measures.
This atlas treats Aramid as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: low radial; fibre anisotropic. Insulation score 36/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: inherently FR vs commodity PA. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: DuPont 1965 Kwolek, United States. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: nomex. Circularity mark 38/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Aramid honest.
Higher modulus, different impact story. 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 zone where heat or chemistry changes the datasheet.
The label keeps Aramid, , and 500. “Defects” is the condition on the figure.500
