Polycrystalline Alumina Fiber (Pure Aluminum Fiber)
Catalog NO.: AIMRSE-CER-024 Category: Polycrystalline Alumina Fiber
Polycrystalline Alumina Fiber is a crystalline refractory fiber. It is made from metallic aluminum powder and other chemical raw materials via special chemical processes. Classified into mullite, high-alumina and pure alumina fibers, it can be processed into blocks, blankets, boards and papers, ideal for high-temperature insulation scenarios like industrial furnaces and aerospace equipment.
