What “the material” actually is
硅橡胶 is sold as grades, not as a single substance. Chemistry [R2SiO]n, density ~1.1–1.5 g/cm³, heat band elastomer; resins cure.
This atlas treats 硅橡胶 as a system: mill route, coatings, tests and the cavity it sits in.

硅橡胶 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 硅橡胶 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.

Deep dive: 硅橡胶
硅橡胶 ([R2SiO]n) is a family of grades whose density ~1.1–1.5 g/cm³, heat band elastomer; resins cure, and fire letter often high LOI vs organic rubbers.
Heat, fire and insulation
Conductivity note: ~0.2 W/m·K; filled greases conduct. Insulation score 42/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: often high LOI vs organic rubbers. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
How it is made and used
Origin: Kipping / Rochow 1940s, United Kingdom / US. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span buildings to defence / safety. Pairings matter: rubber.
Market and circularity
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 40/100. Ask which scrap, which certificate, which year.

常见问题
Is 硅橡胶 non-combustible?
Declared reaction class in this atlas: often high LOI vs organic rubbers. Assemblies still need resistance tests.
Does 硅橡胶 insulate?
Thermal mark 42/100 versus the atlas. Conductivity note: ~0.2 W/m·K; filled greases conduct.
What is the density band?
~1.1–1.5 g/cm³
How is it made?
Origin story: Kipping / Rochow 1940s (United Kingdom / US).
Can it be recycled?
Circularity mark 40/100 — editorial, route-specific.
Typical melting or failure heat?
elastomer; resins cure
What should it be paired with?
rubber: The carbon-chain tyre elastomer.
Where is it specified?
Buildings, transport, energy and consumer goods — see the uses chapter.
