Alumino-Silicate Glass Wool (ASW)

  • Also known as “refractory ceramic fibre” (RCF)
  • Invented in 1942
  • Commercialized in the 1950s
  • Mainly used for products in industrial high-temperature applications
  • High chemical resistance
  • Typically used from 600 °C to 1400 °C

Alumino-silicate glass wools, also known as “refractory ceramic fibre” (RCF), are amorphous fibres produced by melting a combination of Al2O3 and SiO2 (see also EN 1094-1; VDI 3469 Parts 1 and 5).

Products made of alumino-silicate glass wools are generally used at application temperatures > 900 °C in industrial equipment like furnaces and kilns under critical application conditions, in fire protection and in automotive exhaust systems.

ASW and REACH - Facts and Consequences

Substances considered to be of very high concern (SVHC) may be subjected to authorization. Some of the ASW/RCF wools have been identified as SVHC since 13 January 2010. See ECFIA position on the issue.
