👨‍🚒Comment on le fabrique

01 Feedstock

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

02 Conversion

DuPont 1960s

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.

Nomex process path

Nomex heat & fire

Energy in, class out.

1. Heat — in
2. Nomex — mat
3. λ / char — out
4. Ignition — fire
5. Euroclass — class
6. Assembly — sys

Envelope

Melting/softening does not melt; decomposes ~400 °C+; conductivity low (fibre); papers electrically insulating.

Environment

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

Code

Fire class inherently FR textile is a starting letter, not a wall rating.
