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