CCEWOOL® RCF Blanket HPS 2300

CCEWOOL® Ceramic Fiber Blanket HPS 2300, purified from raw materials with fewer impurities, is made from high-purity refractory ceramic fiber spun fiber. Compared to RCF Blanket S, this product is whiter and has a lower thermal conductivity. It contains no organic binders. Manufactured through a unique internal needle punching process, with tensile strength exceeding 85KPa, providing higher performance and longer lifespan in applications involving heat flow or chemical corrosion. 

CCEWOOL® Ceramic Fiber Blanket HPS 2300 insulation material offers a variety of thickness, width, and density.


  • 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 blankets.

  • Maximum Tensile Strength

    Tensile strength refers to the fiber blanket's ability to resist breaking under tension. Utilizing our innovative double-sided needling technique, our fiber blankets exceed 85 Kpa in tensile strength, effectively withstanding impacts in harsh environments and significantly extending their service life.

  • 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.
