CCEWOOL® RCF Blanket LZ 2550

CCEWOOL® Ceramic Fiber Blanket LZ 2550 is primarily made from refractory ceramic fiber spun fiber as raw material with properly amount of Zr2O3 ,double-sided internal needle punching process. It is a lightweight, flexible refractory fiber insulation material resistant to high temperatures up to 1400°C (2550°F). 

CCEWOOL® Ceramic Fiber Blanket LZ 2550 exhibit excellent toughness, elasticity, and workability, making them versatile high-temperature insulation products.


  • 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.

Features of Ceramic Fiber Blanket LZ 2550

    CCEWOOL® RCF Blanket LZ 2550 offers high compressive strength, ensuring durability and a long service life even in demanding applications.

  • Low Heat Capacity and Low Thermal Conductivity

    This blanket provides excellent insulation with low heat capacity and low thermal conductivity, effectively minimizing heat loss.

  • Non-Brittle Material with Good Toughness

    The material is non-brittle and has good toughness, making it resistant to cracking and breaking under stress.

  • Small Dimensional Tolerance and Good Flatness

    With precise dimensional tolerance and good flatness, the blanket ensures a snug fit and reliable performance in various applications.

  • Easy to Cut and Install, Convenient for Construction

    CCEWOOL® RCF Blanket LZ 2550 is easy to cut and install, simplifying construction and reducing installation time and labor costs.

  • Excellent Resistance to Wind Erosion

    The blanket has excellent resistance to wind erosion, maintaining its integrity and insulating properties in windy conditions.

  • Continuous Production with Uniform Fiber Distribution and Stable Performance

    Produced continuously with uniform fiber distribution, the blanket ensures consistent performance and reliability.

  • Excellent Sound Absorption and Noise Reduction Performance

    In addition to thermal insulation, the blanket provides excellent sound absorption and noise reduction, improving the acoustic environment in various settings.
