Quick answers
Is Natural rubber non-combustible?
Declared reaction class in this atlas: combustible; tyres are a fire load. Assemblies still need resistance tests.
Does Natural rubber 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

Prices are bands. A 2024 coil is not a 2026 contract. Labour and certification often dwarf the commodity.
Producers listed are landmarks for orientation, not a ranking or a procurement list.

Global trade
Natural rubber moves as coils, bales, boards or chemicals — check HS codes, not vibes.
