Quick answers
Is Polyester non-combustible?
Declared reaction class in this atlas: melts and drips unless FR. Assemblies still need resistance tests.
Does Polyester 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

Prices are bands. A 2024 coil is not a 2026 contract. Labour and certification often dwarf the commodity.
Producers listed are landmarks for orientation, not a ranking or a procurement list.
