Description of Polycrystalline Mullite Fiber Board

Polycrystalline mullite fiber board is made of polycrystalline mullite fiber cotton compressed together using organic and inorganic adhesives by wet vacuum suction filter process. Fiber board has characteristics of excellent strength, anti-scouring, easy processing and cutting. As a multi-purpose product, polycrystalline mullite fiber board can be applied to high temperature heat surface of furnace lining.

Features of Polycrystalline Mullite Fiber Board

Low heat capacity and low thermal conductivity
Non-brittle material, good elasticity
Excellent thermal stability
Resisting wind erosion, long service life
Excellent thermal shock resistance
Excellent spalling resistance performance
Easy to be molded and cut

Applications of Polycrystalline Mullite Fiber Board

High temperature sealing gasket
Anti-scour parts of lining inner paste
Hot surface material of high temperature furnace lining
Heating device thermal insulation
Furnace door and body filling material
