Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number. Natural rubber is sold as grades, not as a single substance. Chemistry (C5H8)n cis-1,4, density ~0.92 g/cm³, heat band elastomer; decomposes on heat.

Natural rubber 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 Natural rubber with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Origin: Mesoamerican use / Goodyear 1839 / Wickham 1876, Amazonia → Malaysia. The process chapter follows feedstock → conversion → forming → finish → install. Natural rubber ((C5H8)n cis-1,4) is a family of grades whose density ~0.92 g/cm³, heat band elastomer; decomposes on heat, and fire letter combustible; tyres are a fire load.
