PROPERTIES
Our alkaline earth silicate fiber mat 1400 ° C belongs to the last generation of the proven, groundbreaking technology for low bio-resistant fibers. Our alkaline earth silicate fiber mat 1400 ° C is manufactured using modern defibration techniques combined with a new proprietary processing technique, which offers a classification level of 1400 as well as a higher application temperature limit for applications up to 1300 ° C. The needled mat is completely inorganic and retains its strength, flexibility and thermal properties without generating smoke in many work environments. Our alkaline earth silicate fiber mat 1400 ° C is available in various density and thickness combinations and can be used in a variety of high temperature applications.

PRODUCT TYPE
MATERIAL
Alkaline earth silicate fiber high temperature wool (AES Alkaline Earth Silicate Wool) consist of a mix of amorphous fibers that melt and then rapidly solidify a combination of silicon dioxide SiO2 and calcium oxide (CaO) with or without magnesium oxide (MgO). The fiber can be refined with other additives or a change in the material mix (addition of zirconium oxide (ZrO2) have a temperature resistance of up to 1260 ° C.
