Polycrystalline mullite fiber board is an ultra light high-temperature refractory fiber with a single mullite phase as the main crystal phase. It can be used as insulating material in high-temperature thermal equipment below 1600 ℃ for a long time. It has the characteristics of low bulk density, low thermal conductivity, small shrinkage, and excellent chemical stability. Polycrystalline mullite fiber products mainly include PMF polycrystalline mullite blanket, polycrystalline mullite veneer block (PMF1600/1700), PMF polycrystalline mullite fiber module, etc.
