Quick answers
Is PTFE non-combustible?
Declared reaction class in this atlas: high OI but pyrolysis fumes. Assemblies still need resistance tests.
Does PTFE insulate?
Thermal mark 32/100 versus the atlas. Conductivity note: ~0.25 W/m·K.
What is the density band?
~2.2 g/cm³
How is it made?
Origin story: DuPont 1938 Plunkett (United States).
Can it be recycled?
Circularity mark 24/100 — editorial, route-specific.
Typical melting or failure heat?
~327 °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.
