CCEWOOL® Ceramic Fiber Shapes is made from high quality refractory ceramic fiber bulk as raw material, through vacuum forming process. This product is developed into unshaped product with both superior high-temperature rigidity and self-supporting strength. 

We produce CCEWOOL® Unshaped Vacuum Formed Ceramic Fiber to fit for the demand for some specific industrial sector production processes. Depending on performance requirements of the unshaped products, different binders and additives are used in production process. All unshaped products are subject to relatively low shrinkage in their temperature ranges, and maintain a high thermal insulation, lightweight and shock resistance. The non-burnt material can easily be cut or machined. During use, this product shows excellent resistance to abrasion and stripping, and can not be wetted by most molten metals.


  • Ultra-Low Shot Content

    Shot content is a crucial factor in determining the thermal conductivity of fibers. Using a unique shot 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 boards.

  • Strongest compressive strength

    Compressive strength refers to the fiber shapes's ability to resist breaking under pressure. 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 compressive strength.

  • 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 Ceramic Fiber Shapes

  • Versatility in Shape and High Dimensional Accuracy

    CCEWOOL® LBP Shapes can be manufactured into various complex shapes with high dimensional accuracy. This flexibility allows for custom solutions tailored to specific needs, ensuring a precise fit and optimal performance in diverse industrial applications.

  • Direct Flame Contact Without Emissions

    These shapes can withstand direct contact with flames without emitting any odors or volatile gases, even at high temperatures. This ensures a safe and clean working environment, making them ideal for applications involving open flames or high heat.

  • High Mechanical Strength and Gas Flow Resistance

    The CCEWOOL® LBP Shapes are designed with high mechanical strength, providing resistance to deformation and wear. They are also resistant to gas flow, ensuring stability and durability in high-pressure or harsh operating conditions.

  • Low Shrinkage and Thermal Conductivity

    These shapes have low shrinkage and low thermal conductivity, offering excellent insulation properties while maintaining structural integrity over time. This feature ensures efficient thermal management and longevity in high-temperature environments.

  • Excellent High-Temperature Strength and Stability

    CCEWOOL® LBP Shapes maintain excellent strength and thermal stability even at high temperatures. This ensures consistent performance and reliability, making them suitable for demanding industrial applications that require materials to withstand extreme heat while maintaining their properties.
