Premium Refractory Thermal Polycrystalline Alumina Fiber

Product Description:

SUNTHERM ALWOOL 95-M is a high-performance polycrystalline alumina fiber engineered for specialized industrial applications beyond conventional insulation. Composed primarily of high-purity alumina (Al₂O₃) with a balanced silica (SiO₂) content, it is manufactured using internationally recognized sol‑gel technology-a process that ensures superior material consistency and purity.

ALWOOL 95-M features a brilliant white appearance, a smooth and pliable fiber structure, and excellent resilience. Its notably high specific surface area, combined with outstanding thermal stability, gives it a distinct advantage in applications requiring both thermal durability and active surface interaction.

These unique properties make SUNTHERM ALWOOL 95-M an ideal solution for high‑temperature filtration systems, catalytic combustion processes, and environmental exhaust gas treatment. Whether used as a durable filter medium or as a catalyst support substrate, it delivers consistent performance, long service life, and reliable operation under extreme thermal conditions.

 

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
