1600C Alumina Fiber Insulation Blanket

Product Description:

1600C Alumina Fiber Insulation Blanket is manufactured using an advanced sol-gel process combined with precision double-sided needle-punching technology, producing a high-performance insulation material with a strong, uniform fiber structure. This process significantly enhances tensile strength and mechanical integrity, delivering excellent durability even in the most demanding operating conditions. The blanket offers outstanding thermal stability at continuous operating temperatures up to 1600°C, maintaining its structural integrity with minimal shrinkage or deformation. It also provides superior resistance to chemical attack and thermal shock, making it ideal for aggressive industrial environments. Thanks to its low thermal conductivity, the blanket ensures high insulation efficiency, reducing energy loss and improving overall system performance. With excellent dimensional stability and long-term reliability, the 1600°C Alumina Fiber Blanket is widely used in demanding high-temperature applications, including industrial furnaces, kilns, petrochemical equipment, and thermal processing systems.
