👨‍🚒Como se fabrica

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.
