Aramid in : Kevlar 29
Read the condition on Aramid before the nickname. Year , line “Kevlar 29,” figure 29. If a salesperson quotes a single “safety score”, ask which standard, which thickness, which year.
Scores compare Aramid 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.
Aramid (PPTA (para) / meta-aramid cousin Nomex) is a family of grades whose density ~1.44 g/cm³, heat band does not melt; decomposes ~500 °C, and fire letter inherently FR vs commodity PA. Aramid is sold as grades, not as a single substance. Chemistry PPTA (para) / meta-aramid cousin Nomex, density ~1.44 g/cm³, heat band does not melt; decomposes ~500 °C.
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.
The label keeps Aramid, , and 29. “Kevlar 29” is the condition on the figure.29
