CCEWOOL® Intumescent RCF Paper

CCEWOOL® Intumescent Ceramic Fiber Paper is produced from a mixture of high purity refractory ceramic fiber, natural graphite fine flakes, and organic binders through a fiber washing process. 

At about 1200 ℉ (649 ℃), CCEWOOL® Intumescent Ceramic Fiber Paper expands up to maximum of 400% of its thickness. This feature serves as excellent material for gasket and sealing applications.


  • Ultra-Low Shot Content

    Shot content is a crucial factor in determining the thermal conductivity of fibers. Using a nine-stage slag removal process, our fibers achieve ultra-low shot content, demonstrating excellent thermal performance with low thermal conductivity and superior insulation properties in continuous high-temperature environments.

  • Minimal Shrinkage Rate

    Strict control of harmful impurities is essential for reducing thermal shrinkage and enhancing heat resistance. Through rigorous raw material management, we reduce impurity content to below 1%, ensuring low thermal shrinkage and high heat resistance in our fiber papers.

  • Strongest Tear Resistance

    Tear resistance refers to the tensile strength of fiber paper. Using a fully automatic drying system, the drying process is faster and more thorough, achieving deep drying in 2 hours with uniform results. This ensures the product has superior tear resistance.

  • Lowest Thermal Conductivity

    Through strict quality control and high-standard production processes, CCEWOOL® minimizes shot content and meticulously controls bulk density, achieving the lowest thermal conductivity. This provides customers with exceptional insulation performance and more efficient energy-saving solutions.

Features of Intumescent Ceramic Fiber Paper

  • Low thermal capacity

    CCEWOOL® Intumescent RCF Paper has a minimal thermal capacity, meaning it does not retain heat energy extensively.

  • Low thermal conductivity

    The paper exhibits excellent thermal insulation properties, minimizing the transfer of heat through its structure. This characteristic makes it effective in applications where thermal insulation is crucial.

  • Excellent electrical insulation properties

    CCEWOOL® Intumescent RCF Paper provides high resistance to electrical currents, ensuring reliable insulation in electrical applications. It prevents electrical conductivity and associated hazards.

  • Excellent machining performance

    This denotes the paper's ease of handling during fabrication processes such as cutting, shaping, or forming. It maintains structural integrity and quality throughout machining operations.

  • High strength, tear resistance

    The paper is strong and resilient against tearing, offering durability and reliability in various operational conditions. It withstands mechanical stress and maintains its form under pressure.

  • High flexibility

    It demonstrates flexibility, allowing it to bend or conform to curved surfaces without cracking or breaking. This flexibility enhances its applicability in diverse installation scenarios.

  • Low shot content

    CCEWOOL® Intumescent RCF Paper contains minimal loose particles or debris, ensuring cleanliness and reducing the risk of contamination in sensitive environments.
