High Purity Polycrystalline Alumina Fiber Blanket
Product Description:
The 1600 Grade Industrial Alumina Fiber Blanket is produced through advanced sol-gel processing combined with precision needle-punching technology. It features a uniform fiber structure, excellent flexibility, and superior mechanical strength, enabling stable long-term operation in high-temperature environments.
With a maximum service temperature of up to 1600°C, the product provides excellent thermal stability, thermal shock resistance, and chemical corrosion resistance. It exhibits low shrinkage at high temperatures and resists deformation effectively. In addition, its low thermal conductivity delivers outstanding insulation and energy-saving performance, significantly reducing heat loss.
It is widely applied in industrial furnaces, kilns, petrochemical equipment, heat treatment systems, and other high-temperature applications.
Product Features:
▲ Excellent high-temperature resistance and thermal stability
▲ Low heat storage, low thermal conductivity, and extremely low shot content
▲ High tensile strength with excellent hot-state mechanical performance
▲ Outstanding chemical corrosion resistance, especially against alkali attack
▲ Excellent delamination resistance with smooth and even surface quality
▲ High thermal reflectivity for enhanced energy-saving performance
Product Applications:
▲ Refractory and thermal insulation linings for industrial kilns and furnaces
▲ High-temperature insulation equipment and pipelines
▲ High-temperature sealing gaskets
▲ High-temperature filtration media
▲ Substrate material for automotive three-way catalytic converters
▲ Aerogel thermal insulation composites
▲ Raw material for modules and folded blocks
