Полиэстер 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 Полиэстер 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.

Глубокое введение

Deep dive: Полиэстер

Полиэстер ((C10H8O4)n PET) is a family of grades whose density ~1.38 g/cm³, heat band ~250–260 °C, and fire letter melts and drips unless FR.

What “the material” actually is

Полиэстер is sold as grades, not as a single substance. Chemistry (C10H8O4)n PET, density ~1.38 g/cm³, heat band ~250–260 °C.

This atlas treats Полиэстер as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

Conductivity note: low solid; fabrics trap air. Insulation score 50/100 is relative to 32 entries — metals lose, VIPs and aerogels win.

Fire letter in editorial use: melts and drips unless FR. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

How it is made and used

Origin: Whinfield & Dickson 1941 / DuPont Dacron, United Kingdom / US. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: nylon.

Market and circularity

Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.

Circularity mark 34/100. Ask which scrap, which certificate, which year.

Частые вопросы

Is Полиэстер non-combustible?

Declared reaction class in this atlas: melts and drips unless FR. Assemblies still need resistance tests.

Does Полиэстер insulate?

Thermal mark 50/100 versus the atlas. Conductivity note: low solid; fabrics trap air.

What is the density band?

~1.38 g/cm³

How is it made?

Origin story: Whinfield & Dickson 1941 / DuPont Dacron (United Kingdom / US).

Can it be recycled?

Circularity mark 34/100 — editorial, route-specific.

Typical melting or failure heat?

~250–260 °C

What should it be paired with?

nylon: The polyamide rival: tougher wet, different dye class.

Where is it specified?

Buildings, transport, energy and consumer goods — see the uses chapter.
