Polycrystalline Alumina Fiber in Industrial Insulation Solutions

Product Description:

Polycrystalline Alumina Fiber in Industrial Insulation Solutions, SUNTHERM ALWOOL 95-M is an advanced polycrystalline alumina fiber material primarily composed of alumina (Al₂O₃) and silica (SiO₂), manufactured using internationally advanced sol–gel technology. As a new-generation ultra-lightweight high-temperature insulation material, it features a pure white appearance with a smooth, soft, and resilient fiber structure, along with an exceptionally high specific surface area.

Thanks to its excellent thermal stability and structural performance, this material is widely used in catalytic combustion and environmental exhaust gas treatment applications, serving as an ideal high-temperature filtration medium and catalyst carrier.

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
