Natural rubber in : SBR crash programme
Read the condition on Natural rubber before the nickname. Year , line “SBR crash programme,” figure 1. Natural rubber did not arrive as a finished commodity. Mesoamerican use / Goodyear 1839 / Wickham 1876 around Amazonia → Malaysia still explains who makes it and which tests it sits in.
Scores compare Natural rubber 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.
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. 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.
This atlas treats Natural rubber as a system: mill route, coatings, tests and the cavity it sits in. 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.
The label keeps Natural rubber, , and 1. “SBR crash programme” is the condition on the figure.1
