CCEWOOL® RCF Board DB 2012

CCEWOOL® Ceramic Fiber Board DB 2012 is a refractory ceramic fiber backboard made primarily from alumina-silica fiber , natural refractory materials, and a small amount of organic binders. It is processed using a fully automated continuous production line. The product has a high fiber content and features characteristics such as high-temperature resistance, lightweight, and thermal shock resistance. 

CCEWOOL® Ceramic Fiber Board DB 2012 can be used in various applications, including industrial kiln and furnace lining, wall lining, lining materials, insulation for electric heating furnaces, ceramic shuttle kilns, tunnel kilns, and roller kilns, providing strong support for energy saving, consumption reduction, high quality, and high yield in kilns.


  • 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 board'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.
