Alumina Needled Blanket

Alumina Fiber Needled Mat is made of high-alumina polycrystalline fiber (alumina fiber with a content of more than 72%), which is a high-quality lightweight high-temperature resistant polycrystalline non-intumescent liner material. It has excellent aging durability, blowing resistance and erosion resistance, and the temperature resistance can reach 1500℃. It is now widely used as a gasket material for automotive three-way catalytic converters, and is suitable for various packaging technologies, providing customized design solutions.

Alumina Needled Blanket is a high-performance refractory insulation material made from high-purity alumina fibers through an advanced needle-punching process. Designed for extreme heat resistance and long-term thermal stability, Alumina Needled Blanket can withstand very high operating temperatures while maintaining excellent mechanical strength and low thermal conductivity. It is widely used in industrial systems that require reliable insulation and energy efficiency.

In practical applications, Alumina Needled Blanket offers outstanding resistance to thermal shock, chemical corrosion, and mechanical vibration. Its uniform fiber structure and dense interlocking design provide strong durability and prevent fiber shrinkage under prolonged high-temperature exposure. The flexible and lightweight structure allows easy cutting, shaping, and installation on furnaces, kilns, reactors, and high-temperature pipelines. In addition, Alumina Needled Blanket helps reduce heat loss and improve temperature control, supporting stable production processes.

Furthermore, Alumina Needled Blanket is extensively applied in metallurgy, petrochemical, ceramic, glass, power generation, and aerospace industries. It is commonly used for furnace linings, heat treatment equipment, fire barriers, and thermal protection systems. With strict quality control, stable production capacity, and customizable thickness and density, Alumina Needled Blanket helps manufacturers improve energy efficiency, enhance operational safety, and ensure long-term reliable performance in extreme industrial environments.
