Vacuum formed insulation alumina ceramic fiber board is importance parts of high temperature furnace, 1700 and 1800 Polycrystalline mullite fiber board are extensions to the ceramic fiber product line. These alumina ceramic fiber board products exhibit excellent thermal stability (low shrinkage) at very high operating temperatures. Another benefit of Polycrystalline mullite alumina ceramic fiber board product is their extremely high modulus of rupture in both the green and fired state. Because of this strength, both 1700 and 1800 are very well suited for applications where sag resistance is critical.

Typical Applications of Polycrystalline mullite alumina ceramic fiber board:

High-temperature Laboratory
