Polycrystalline Mullite Fiber Bulk
Polycrystalline Mullite Fiber Bulk, also known as PCW Fiber Bulk, is a high-purity loose fiber developed for demanding high-temperature insulation applications. With excellent thermal stability, low heat storage, and good resistance to thermal shock, it is suitable for industrial furnace insulation, high-temperature filling, sealing, and refractory systems.
Mindelun supplies 1600°C Polycrystalline Mullite Fiber Bulk for direct insulation applications and as a raw material for producing high-performance PCW insulation products. Its loose and flexible structure makes it suitable for filling gaps, joints, irregular spaces, and other areas where rigid insulation materials are difficult to install.
