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.
Product variations
