Nylon in 1935: Carothers 66
The behaviour of Nylon is written as 1935’s “Carothers 66,” fixed by 66. An advert’s adjective is not a melting point. “Room temperature” alone is not a figure. Carothers’ polyamide — stockings, tyre cord, climbing rope and a melt-drip fire personality.
Nylon is one of 32 materials in this atlas, grouped under textiles: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue. Scores compare Nylon 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. Nylon (PA6 / PA66) is a family of grades whose density ~1.14 g/cm³, heat band PA6 ~220 °C; PA66 ~260 °C, and fire letter combustible, melt-drip.
Nylon is sold as grades, not as a single substance. Chemistry PA6 / PA66, density ~1.14 g/cm³, heat band PA6 ~220 °C; PA66 ~260 °C. This atlas treats Nylon as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: low. Insulation score 30/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
“Carothers 66” for Nylon in 1935 carries 66. Praise without that figure is not a property.1935
