Advanced Polycrystalline Alumina Fiber

Advanced Polycrystalline Alumina Fiber is a premium-grade polycrystalline alumina fiber material composed primarily of high-purity alumina (Al₂O₃) and silica (SiO₂), produced using internationally advanced sol–gel processing technology.

This innovative material features a pure white appearance with a smooth, soft, and flexible fiber structure, offering excellent resilience and an exceptionally high specific surface area. These characteristics enable superior performance in high-temperature environments where both thermal insulation and structural integrity are critical.

With outstanding thermal stability, low shrinkage, and excellent resistance to thermal shock, ALWOOL 95-M performs reliably under continuous high-temperature conditions. Its unique microstructure makes it particularly suitable for use as a high-efficiency filtration medium and catalyst carrier.

It is widely applied in catalytic combustion systems and industrial exhaust gas treatment processes, providing enhanced efficiency, durability, and environmental performance.

Product Features:

Excellent specific surface area parameters, suitable for adsorption and catalysis applications;

Superior resistance to acids and alkalis;

Excellent electrical insulation properties;

High design flexibility; products with varying properties can be obtained by adjusting chemical composition and heat treatment processes.

Product Applications:

Raw material for fiber products (e.g., fiber blankets, felts, paper, boards, shaped parts, etc.)

Catalyst carrier material

High-temperature filtration material

Reinforcement for composites such as metal matrix, ceramic matrix, and resin matrix composites

Mat material for three-way catalytic converters

Thermal insulation material for the automotive industry

Thermal insulation filling material for high-temperature kilns and furnaces
