CCEWOOL® RCF bulk specialized for vacuum formed shapes

CCEWOOL® Ceramic Bulk Fiber is produced by melting high-purity raw materials such as clay grog, aluminum oxide powder, silica powder, and zircon sand in an industrial electric furnace at high temperatures to form a fluid. Then, it is transformed into fiber-like structures through processes like compressed air blowing or spinning with a centrifuge, and collected to create ceramic fiber cotton.

CCEWOOL® Ceramic Bulk Fiber can resist most types of chemical corrosion. They are lightweight, durable, have low heat storage capacity, effectively save energy, and exhibit excellent resistance to thermal shocks, making them suitable for use in harsh environments. CCEWOOL® Ceramic Bulk Fiber serves as a raw material for the production of refractory ceramic fiber blankets, boards, papers, and can also be directly used in various high-temperature applications such as high-temperature insulation and packaging materials.


  • Ultra-Low Shot Content

    Shot content is a crucial factor in determining the thermal conductivity of fibers. Using imported high-speed centrifuges, 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 modules.

  • Lowest Thermal Conductivity

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

  • Versatile Applications

    Can be used as raw material for RCF blankets, boards, and paper, or directly for high-temperature insulation and various other high-temperature applications.

Features of Ceramic Fiber bulk specialized for vacuum formed shapes

  • Unlubricated

    CCEWOOL® RCF bulk is produced without any lubricants, ensuring it is pure and suitable for high-temperature and chemically sensitive applications where contamination must be avoided.

  • Low Heat Capacity and Low Thermal Conductivity

    This bulk material has a low heat capacity and low thermal conductivity, effectively minimizing heat transfer and enhancing energy efficiency, making it an excellent choice for thermal insulation.

  • Excellent Chemical Stability

    The material exhibits excellent chemical stability, maintaining its properties and performance even when exposed to harsh chemicals, ensuring long-lasting durability and reliability.

  • Superior Thermal Stability, Resistant to Powdering at High Temperatures

    CCEWOOL® RCF bulk offers superior thermal stability, remaining intact and resistant to powdering even at high temperatures. This ensures consistent performance and structural integrity in extreme heat conditions, making it ideal for vacuum formed shapes.
