Silikon 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 Silikon 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.

Tiefe Einführung

Deep dive: Silikon

Silikon ([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.

What “the material” actually is

Silikon 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 Silikon as a system: mill route, coatings, tests and the cavity it sits in.

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.

Häufige Fragen

Is Silikon non-combustible?
Declared reaction class in this atlas: often high LOI vs organic rubbers. Assemblies still need resistance tests.
Does Silikon 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.
