Insulation up to 1,850 °C with high-quality AES, PCW, and ASW wool.
This material can be used for insulation up to 1,850 °C. Due to the chemical element weight ratio, the earth's crust contains over 82% oxygen, silicon, and aluminum. The inorganic, textured ceramic fiber is manufactured from this raw material combination and is therefore naturally fire-resistant and heat-insulating.
Advanced chemical technology makes it possible today to precisely produce these fibers by melting various oxides at very high temperatures.
Polycrystalline wool (alumina wool), PCW wool for short, is produced using the innovative Sol-Gel process from aqueous spinning solutions.
It consists of fibers with an alumina content (Al₂O₃) of over 70% by weight. The Sol-Gel process initially creates water-soluble green fibers, which are uniquely crystallized through heat treatment.
Application Temperature: This high-performance wool type is typically used at very high application temperatures exceeding 1,300 °C.
Due to its enormous temperature resistance, PCW ceramic fiber products are in high demand in key industries. Typical areas of application include demanding mold and industrial furnace construction, the automotive industry, and large parts of the ceramics industry.
