에어로젤 is one of 32 materials in this atlas, grouped under advanced: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.

Scores compare 에어로젤 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: 에어로젤

에어로젤 (SiO2 network + >90% air) is a family of grades whose density ~0.003–0.15 g/cm³, heat band silica sinters; organic aerogels burn, and fire letter silica A1; polymer aerogels not.

What “the material” actually is

에어로젤 is sold as grades, not as a single substance. Chemistry SiO2 network + >90% air, density ~0.003–0.15 g/cm³, heat band silica sinters; organic aerogels burn.

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

Heat, fire and insulation

Conductivity note: silica blankets ~0.015–0.025 W/m·K class. Insulation score 98/100 is relative to 32 entries — metals lose, VIPs and aerogels win.

Fire letter in editorial use: silica A1; polymer aerogels not. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

How it is made and used

Origin: Kistler 1931; NASA / Aspen 1990s–, United States. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: vacuum-insulation.

Market and circularity

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

Circularity mark 50/100. Ask which scrap, which certificate, which year.

자주 묻는 질문

Is 에어로젤 non-combustible?

Declared reaction class in this atlas: silica A1; polymer aerogels not. Assemblies still need resistance tests.

Does 에어로젤 insulate?

Thermal mark 98/100 versus the atlas. Conductivity note: silica blankets ~0.015–0.025 W/m·K class.

What is the density band?

~0.003–0.15 g/cm³

How is it made?

Origin story: Kistler 1931; NASA / Aspen 1990s– (United States).

Can it be recycled?

Circularity mark 50/100 — editorial, route-specific.

Typical melting or failure heat?

silica sinters; organic aerogels burn

What should it be paired with?

vacuum-insulation: The other ultra-low λ panel.

Where is it specified?

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