  • 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.

  • Fraunhofer Certification

    Certified by the Fraunhofer Laboratory in Europe for solubility testing.

Features of Low Biopersistent Fiber Bulk

  • Excellent Thermal Shock Resistance

    CCEWOOL® LBP Bulk can withstand rapid temperature changes without cracking or degrading, ensuring reliable performance in environments with fluctuating temperatures.

  • Excellent Thermal Insulating Performance

    This bulk material provides superior thermal insulation, effectively retaining heat and minimizing heat loss, making it ideal for high-temperature applications.

  • Low Thermal Conductivity

    The bulk material has low thermal conductivity, which significantly reduces heat transfer, enhancing energy efficiency in various insulation applications.

  • Low Heat Storage

    CCEWOOL® LBP Bulk has low heat storage capacity, allowing for quicker heating and cooling cycles, which improves overall energy efficiency and thermal management.

  • Low Bio-Persistence

    The material is designed with low bio-persistence, making it safer for use and handling, and reducing health risks associated with inhalation.
