Nylon in : Parachutes & cord

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. Fire letter in editorial use: combustible, melt-drip. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide. Origin: DuPont 1935–38, United States. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: polyester. Circularity mark 32/100. Ask which scrap, which certificate, which year.
