PTFE in 2000s: GenX / alternatives
Read the condition on PTFE before the nickname. Year 2000s, line “GenX / alternatives,” figure 327. Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.
This atlas treats PTFE as a system: mill route, coatings, tests and the cavity it sits in. 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.
Origin: DuPont 1938 Plunkett, United States. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: silicone. Circularity mark 24/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep PTFE honest.
The other high-temp elastomer/plastic in kitchens. The cheap olefin PTFE replaced in hostile chemistry. Lined steel vs glass-lined — different plants choose differently. High-temp textile vs high-temp plastic. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation.
The label keeps PTFE, 2000s, and 327. “GenX / alternatives” is the condition on the figure.2000s
