CCEWOOL® PCW Blanket 2912

CCEWOOL® Polycrystalline Wool Fiber Blanket 2912 is an ideal choice for high-temperature and chemically corrosive applications.

CCEWOOL® Polycrystalline Wool Fiber Blanket 2912 is produced using sol-gel technology to create fibers of specific dimensions, which are then formed into blankets through a double-sided needling process. The product exhibits excellent strength and flexibility. It is a refractory fiber that exists in the form of mullite crystal phases and maintains its outstanding dimensional stability and elasticity even at high temperatures. The introduction of polycrystalline fiber blankets has effectively filled the gap in the field of fibers for long-term use at temperatures ranging from 1350°C (2462℉) to 1500°C (2732℉).

CCEWOOL® Polycrystalline Wool Fiber Blanket 2912 are more resistant to acids and alkalis than refractory ceramic fibers and perform exceptionally well in high-temperature environments subjected to oxidation, reduction, and chemical corrosion.

CCEWOOL® Polycrystalline Wool Fiber Blanket 2912 is virtually free of shot, resulting in extremely low thermal conductivity and excellent thermal insulation properties.


  • 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.
