In high-temperature insulation systems, efficiency depends on blocking heat flow, not just withstanding high temperatures. Traditional materials with coarse fibers or high shot content create heat-transfer paths that raise shell temperature and energy use.CCEWOOL® refractory ceramic paper solves this by controlling fiber fineness, purity, and structure, achieving ultra-low thermal conductivity and more stable insulation performance.
How does CCEWOOL® achieve ultra-low thermal conductivity?
CCEWOOL® refractory ceramic fiber paper is made from our own high-purity ceramic fiber bulk with impurity content below 1%, preventing crystal transformation or structural degradation at high temperatures. This stability forms the foundation for consistently low thermal conductivity during long-term operation.
During fiber production, the ceramic fiber bulk is formed using imported high-speed centrifuges running at 11,000 r/min, producing finer and more uniform fibers while keeping shot content at ≤15%. Since shot particles create “thermal bridges,” reducing them significantly shortens straight heat-transfer paths and lowers thermal conductivity.
The forming process includes a nine-stage shot-removal system, further minimizing shot content. As a result, CCEWOOL® refractory ceramic paper reaches a thermal conductivity of only 0.12 W/m·K at 1000°C (1832°F), which is 15–20% lower than standard fiber papers.
Wet-forming ensures even fiber distribution, smooth surfaces, and no delamination, creating a continuous micro-porous structure that extends heat-flow paths and increases insulation efficiency by about 20% at the same thickness.
To ensure consistency between batches, CCEWOOL® applies its self-developed Fiber Micro-defect Detection System Based on Image Recognition Technology V1.0, which monitors fiber arrangement, shot content, and thickness uniformity in real time and automatically adjusts process parameters, ensuring stable insulation performance in every batch.
Lower Thermal Conductivity, Higher Equipment Efficiency
In high-temperature systems—such as furnace-door seals, flue insulation, module backing, and casting layers—CCEWOOL® refractory ceramic paper blocks heat more effectively thanks to its low thermal conductivity, low shrinkage, and stable microstructure. This helps maintain more uniform furnace temperatures and reduces energy loss.
Customer results show that using CCEWOOL® refractory ceramic paper can reduce furnace heat loss by 18–25%, cut fuel use by 4–6%, lower furnace-shell temperature by 30–50°C, and extend lining life by over 25%. These improvements come from better fiber structure, low shot content, and consistent manufacturing—not increased thickness.
With high-purity materials, ultra-fine fibers, ultra-low shot content, and intelligent production control, CCEWOOL® refractory ceramic paper extends heat-flow paths, reduces heat loss, and improves energy efficiency. Its insulation performance comes from structure rather than thickness, ensuring long-term stability.
