Babcock & Wilcox
Early kaolin-based ceramic fibres in the US.
Keramikfaser did not arrive as a finished commodity. 1940s–60s US/JP; EU RCF classification 1990s around United States / Japan / EU still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.

Zeitlinie
1942+Babcock & Wilcox
Early kaolin-based ceramic fibres in the US.
1950sNeedled blankets
Furnace lining without firebrick thickness.
1970sModules
Anchored folded blankets for petrochemical heaters.
1988–97EU carcinogen class
RCF classified; workplace rules tightened.
1990sAES / Superwool
Alkaline-earth silicate wools, lower biopersistence claims.
2000sREACH / SCOEL
Exposure limits as the product differentiator.
2010sPolycrystalline Al2O3
Still higher T, different process.
2010sFire-protection wraps
Structural steel and ducts — check which fibre.
2020sRCF substitution
Many EU sites specify AES unless T demands RCF.
2020sRecycling of offcuts
Still immature versus mineral wool.

Knowing this timeline is how to read a mill certificate without treating Keramikfaser as timeless.
