This comparison is limited to reviewed official-source processing and use-context evidence.\n\n## Processing behavior\n\nFEP is described by official FEP sources as melt-processable, while PTFE is generally handled through different fabrication routes in the reviewed source context.\n\n## Melt processability\n\nMelt processability is the core supported distinction for this page and must remain tied to the cited FEP and PTFE source scopes.\n\n## Extrusion and fabrication context\n\nOfficial FEP sources support extrusion-related contexts; PTFE fabrication wording remains bounded to the existing governed PTFE evidence and does not imply a universal process ranking.\n\n## Wire and cable use context\n\nWire and cable are included only as FEP source-backed use-context examples and not as a material recommendation.\n\n## Film and tubing use context\n\nFilm and tubing are included as FEP source-backed contexts; this page does not compare optical behavior, thermal ceilings, or mechanical rankings.\n\n## Manufacturer-specific terminology\n\nManufacturer product names and forms remain source-specific, and this page does not infer cross-brand grade equivalence.\n\n## What this comparison does not cover\n\nThis page excludes quantified thermal ceilings, chemical-service ratings, mechanical rankings, optical claims, cost ranking, and material-selection recommendations.\n\n## Evidence and limitations\n\nEvery technical statement is mapped to a supported claim, source-backed explanation, context-only note, or exclusion decision before publication review.\n","reviewed_at":null,"sources":[{"name":"Sprint 12 PTFE vs FEP trust-reviewed
