- Light weight
- Excellent flexibility
- Good sound insulation
PRODUCT TYPE
MATERIAL
Alkaline earth silicate fiber high temperature wool (AES Alkaline Earth Silicate Wool) consist of a mix of amorphous fibers, which are melted and then rapidly solidified using a combination of silica SiO2 and calcium oxide (CaO) with or without magnesium oxide (MgO). The fiber can be obtained by refining with other additives or a change in the material mix (addition of zirconium oxide (ZrO2) have a temperature resistance of up to 1260 ° C.
