Premium Refractory Thermal Polycrystalline Alumina Fiber
Manufactured using an advanced sol–gel process, Premium Polycrystalline Alumina Fiber is lightweight and flexible, with a high specific surface area. Designed for demanding high-temperature applications, it provides thermal insulation and can also be used in catalytic combustion and exhaust gas treatment systems.
Description
Product Description:
SUNTHERM ALWOOL 95-M is a polycrystalline alumina fiber developed for specialized industrial applications that require more than conventional thermal insulation. Made primarily from high-purity alumina (Al₂O₃) with a controlled silica (SiO₂) content, it is manufactured using sol–gel technology to achieve consistent material quality and purity.
ALWOOL 95-M has a bright white appearance and a smooth, flexible fiber structure. Its high specific surface area and excellent thermal stability make it well suited for applications involving both high temperatures and surface-related processes.
The fiber can be used in high-temperature filtration, catalytic combustion, and exhaust gas treatment systems. Depending on the system design, it can serve as a filter medium or a catalyst support, providing a material option for processes operating under demanding thermal conditions.
Product Features:
- High specific surface area: Suitable for adsorption and catalytic applications.
- Acid and alkali resistance: Offers resistance to acidic and alkaline environments.
- Electrical insulation: Provides effective electrical insulation.
- Flexible material design: Product properties can be tailored by adjusting the chemical composition and heat treatment process.
Product Applications:
Raw material for fiber-based products, including blankets, felts, paper, boards, and custom-shaped components
Catalyst support material
High-temperature filtration media
Reinforcement for metal matrix, ceramic matrix, and resin matrix composites
Mounting mat material for three-way catalytic converters
Thermal insulation for automotive applications
Insulating filler for high-temperature kilns and furnaces
