Exploring Alumina Continuous Fibers: High-Temperature Insulation Solutions by Vulcan Shield Global
In the world of high-performance materials, alumina continuous fibers have established themselves as game-changers for industries requiring exceptional thermal, chemical, and mechanical properties. These fibers are made from high-purity aluminum oxide, crafted through the sol-gel method, which ensures unparalleled strength, flexibility, and thermal stability. At Vulcan Shield Global (Vulcan Shield Global), our lineup of continuous fiber products includes F-72, C-85, and M-99, designed to meet the diverse demands of industries ranging from aerospace to petrochemicals.
What Are Alumina Continuous Fibers?
Alumina continuous fibers are advanced ceramic fibers engineered for high-temperature and demanding environments. These fibers are:
- Highly flexible and capable of being intricately woven into fabrics, ropes, and cloth-like materials.
- Resilient at extreme temperatures, making them indispensable for applications like thermal insulation, high-temperature seals, and structural reinforcements.
- Known for their exceptional chemical resistance, ensuring stability even in corrosive environments.
Vulcan Shield Global’s Continuous Fiber Products
1. F-72: 72% Alumina Content
F-72 alumina fibers are lightweight, flexible, cost-efficient, making F-72 a budget friengly option for medium to high-temperature applications. F-72 also possesses properties like high temperature resistance, high strength, oxidation resistance, and antistatic properties, making it a core material for the production of next-generation refractory products.
The F-72 alumina fiber has a long-term service temperature of 1200°C, with a single fiber diameter of approximately 7-10μm, making F-72 suitable for applications in metal matrix composites. F-72 fibers, with a 72% Al2O3 content, has a soft and flexible texture, making them suitable for the manufacture of textile products. After weaving and braiding, it can be made into various shapes of thermal insulation seals and can also be used for composite reinforcement.
Key Properties: Operates continuously at temperatures up to 1200°C.Resistant to mild acids and alkalis, making it suitable for environments with moderate chemical exposure.Ideal for applications requiring lightweight thermal insulation, such as furnace linings and glass manufacturing.
2. C-85: 85% Alumina Content
The C-85 alumina fiber strikes a balance between cost and performance, with enhanced mechanical strength and thermal stability. C-85 has high structural integrity and is ideal for industrial-grade applications.
Key Properties: Withstands continuous temperatures up to 1300°C.Improved modulus for added structural integrity in high-stress environments. Higher resistance to thermal cycling compared to F-72.
3. M-99: 99% Alumina Content
Microscoptic Cross Section of M-99 Fiber
M-99 alumina fiber is Vulcan Shield Global’s flagship product, offering the highest alumina content (99%). The long-term service temperature of M-99 alumina fiber can reach around 1000-1100℃, with a single fiber diameter of approximately 12-14μm. M-99 is suitable for applications in ceramic, polymer and metal matrix composites. The 99% Al2O3 content effectively controls the material interface effect, exhibits good compatibility with active surfaces, and can be used to produce lightweight and high-strength composite products using winding or prepreg techniques.
Key Properties:
Operates at temperatures exceeding 1000°C.Exceptional modulus and strength, making it ideal for high-stress and high-temperature applications. Chemically inert and resistant to oxidation, even in the harshest conditions.
