PTFE · PTFE is one of 32 materials in this atlas, grouped under polymer
PTFE is one of 32 materials in this atlas, grouped under polymers: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue. Scores compare PTFE with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Conductivity note: ~0.25 W/m·K. Insulation score 32/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: high OI but pyrolysis fumes. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
PTFE · lede
PTFE ((C2F4)n) is a family of grades whose density ~2.2 g/cm³, heat band ~327 °C, and fire letter high OI but pyrolysis fumes. US and UK documents still dominate Google for PTFE: ASTM, NFPA, BS, EN. Always check whether the job is under IBC, Eurocodes or a national annex.
