CCEWOOL® Alumina Fiber Board 2732 for Fabrication

CCEWOOL® Alumina Fiber Board 2732 for Fabrication is a high-performance alumina fiber insulation board developed for demanding high-temperature engineering applications. The product is manufactured from high-purity alumina fibers using a wet vacuum forming process, followed by controlled high-temperature treatment to create a stable fiber structure. This manufacturing process enables the board to maintain excellent thermal stability and structural integrity in operating environments up to 1500°C (2732°F).

Compared with conventional industrial-grade fiber boards, CCEWOOL® Alumina Fiber Board 2732 for Fabrication features improved fiber purity, enhanced structural uniformity, and superior dimensional stability. These optimizations provide lower shrinkage and higher mechanical strength under elevated temperature conditions. The uniform and dense fiber structure also makes the board particularly suitable for Fabrication and secondary processing, allowing it to be cut, drilled, or machined into various engineered insulation components.

CCEWOOL® also provides Fabrication customization services for this product. Based on equipment configurations or engineering drawings, boards can be supplied in customized dimensions, thicknesses, or complex shapes to meet the specific requirements of high-temperature industrial equipment, laboratory furnaces, and aerospace thermal protection systems.

Benefits

  • Higher Temperature Capability

    Compared with standard RCF boards, Alumina Fiber Board offers a higher temperature rating, making it more suitable for demanding high-temperature applications.

  • Lower Shrinkage at Elevated Temperatures

    Alumina Fiber Board maintains better dimensional stability under prolonged high-temperature exposure, reducing shrinkage and helping preserve structural integrity.

  • Better Structural Strength for Engineered Components

    With a denser and more stable fiber structure, Alumina Fiber Board provides higher mechanical strength and rigidity than conventional RCF boards.

  • More Suitable for Precision Fabrication

    Compared with standard RCF boards, Alumina Fiber Board is better suited for cutting, drilling, and machining into complex insulation components for engineered systems.

Features of Alumina Fiber Board 2732 for Fabrication

  • Excellent High-Temperature Stability
