Product Feature

1. **High Strength and High Modulus**: Alumina fibers have extremely high tensile strength and rigidity, maintaining structural integrity under high-stress conditions.
2. **High Temperature Resistance**: These fibers can retain their physical and chemical properties at extreme temperatures, typically withstanding temperatures above 1000°C, and certain types can even endure temperatures exceeding 1500°C.
3. **Chemical Stability**: Alumina fibers exhibit strong resistance to most chemicals, making them less prone to corrosion by acids and bases.
4. **Low Thermal Expansion Coefficient**: Compared to other materials, alumina fibers have a lower thermal expansion coefficient, making them suitable for applications involving thermal cycling.
5. **Insulating Properties**: Alumina fibers possess excellent electrical insulation properties, making them ideal for the production of electrical insulating materials.
 

Application

1. **Aerospace**: Used in the production of high-temperature structural materials, such as insulation layers and heat shields for aircraft engines.
2. **Industrial Furnaces**: Employed as insulation materials in high-temperature furnaces, improving energy efficiency and durability.
3. **Electronics and Electrical Appliances**: Used to manufacture high-temperature insulation materials and electrical insulation layers.
4. **Composite Materials**: As a reinforcement material, alumina fibers can enhance the strength and high-temperature performance of resin-based composites.
5. **Fireproof Materials**: Used in the production of fireproof blankets, fireproof clothing, and other fire-resistant products.

Due to their superior properties, alumina continuous long fiber yarns have a wide range of applications in high-tech fields, particularly where high-temperature resistance, corrosion resistance, and high strength are required.
