CCEWOOL® Super Duty RCF Board

CCEWOOL® Super Duty Ceramic Fiber Board is a new type of refractory and heat insulation material, which is made of refractory ceramic fiber bulk as the main raw material. It can maintain high strength and low thermal conductivity at high temperature.

CCEWOOL® Super Duty Ceramic Fiber Board has tough texture.The bearing capacity at normal temperature is greater than 80 t/m2 and the bearing capacity at high temperature is greater than 40 t/m2. Its compressive strength is more than ten times that of general refractory ceramic fiber board. Its thermal insulation performance is basically the same as that of general refractory ceramic fiber board. It is a kind of high-strength thermal insulation fiber board.

Benefits

  • Advanced Fire-Resistant Insulation Material with Exceptional High-Temperature Performance

    This new fire-resistant insulation material maintains high strength and low thermal conductivity under high-temperature conditions, providing reliable insulation protection in various demanding environments.

  • Compressive Strength Ten Times Higher than Standard Ceramic Fiber Boards

    Its compressive strength exceeds that of typical ceramic fiber boards by over tenfold, while delivering comparable insulation performance to traditional ceramic fiber boards.

  • Efficient Drying for Consistent Quality

    Using a fully automated drying system, the product undergoes deep, uniform drying within two hours, ensuring compressive and flexural strengths above 1.2 MPa, enhancing overall quality and durability.

  • Precision CNC Cutting for High Accuracy

    With fully automated CNC machinery, the product is cut with near-zero dimensional error, meeting the stringent requirements of high-precision applications.

Features of Super Duty RCF Board

  • Excellent Load Bearing Capacity

    Capable of supporting heavy loads without deformation or damage, ensuring reliability in demanding applications.

  • Excellent Thermal Stability

    Performs consistently under high temperatures without losing structural integrity.

  • Excellent Thermal Shock Resistance

    Can withstand rapid temperature fluctuations without cracking or failure.

  • Low Thermal Conductivity

    Minimizes heat transfer, providing efficient thermal insulation.

  • Low Heat Storage

    Stores minimal heat, allowing for quick temperature adjustments and improved energy efficiency.

  • Easily Machined, Cut, and Shaped

    Can be customized with ease for various applications, reducing construction time and effort.
