🪢Comment on le fabrique

01 Feedstock

Ore, monomer, fibre, mineral or scrap that can legally become Nylon.

02 Conversion

DuPont 1935–38

03 Forming

Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.

04 Heat / cure

Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.

05 Finish

Coatings, sizings, facers, galvanizing, anodising, painting.

06 Install

Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.

Primary

Virgin route around United States.

Recycled / secondary

Recycling exists but quality or energy often disappoints.

Specialty

High-spec grades leave the commodity mill.

Site-applied

Coatings, sprays, casts — the factory is sometimes a jobsite.

Nylon heat & fire

Energy in, class out.

Envelope

Melting/softening PA6 ~220 °C; PA66 ~260 °C; conductivity low.

Environment

Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Nylon.

Code

Fire class combustible, melt-drip is a starting letter, not a wall rating.
