ALLTHERM ceramic fiber board is made by ceramic fiber bulk and a little binding agent through vacuum formed. ALLTHERM ceramic fiber board can maintain its mechanical strength after high-temperature heating, and the board includes 6 levels: 1050℃， 1260℃, 1350℃, 1430℃, 1600℃,and 1700℃. ALLTHERM ceramic fiber board can resist the scouring of airflow for its high strength, so it can be the material of internal linings.
ALLTHERM inorganic ceramic fiber board is made by ceramic fiber bulk and inorganic binding agent through vacuum forming. When using the board under the circumstance of high temperature, the pollution gas will not be generated.
Characteristics Applications
