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

Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.

Introducción profunda

Deep dive: Caucho natural

Caucho natural ((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.

What “the material” actually is

Caucho natural 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.

This atlas treats Caucho natural as a system: mill route, coatings, tests and the cavity it sits in.

Heat, fire and insulation

Conductivity note: ~0.15 W/m·K. Insulation score 38/100 is relative to 32 entries — metals lose, VIPs and aerogels win.

Fire letter in editorial use: combustible; tyres are a fire load. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

How it is made and used

Origin: Mesoamerican use / Goodyear 1839 / Wickham 1876, Amazonia → Malaysia. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: silicone.

Market and circularity

Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.

Circularity mark 46/100. Ask which scrap, which certificate, which year.

Preguntas frecuentes

Is Caucho natural non-combustible?

Declared reaction class in this atlas: combustible; tyres are a fire load. Assemblies still need resistance tests.

Does Caucho natural insulate?

Thermal mark 38/100 versus the atlas. Conductivity note: ~0.15 W/m·K.

What is the density band?

~0.92 g/cm³

How is it made?

Origin story: Mesoamerican use / Goodyear 1839 / Wickham 1876 (Amazonia → Malaysia).

Can it be recycled?

Circularity mark 46/100 — editorial, route-specific.

Typical melting or failure heat?

elastomer; decomposes on heat

What should it be paired with?

silicone: The high-temp elastomer NR cannot be.

Where is it specified?

Buildings, transport, energy and consumer goods — see the uses chapter.
