In industrial sealing, insulation gaskets, furnace door seals, and various machined shapes, ceramic fiber paper must withstand cutting, bending, stretching, and installation. However, conventional fiber paper often fails during processing due to:
-
Tearing under slight tension: caused by short fibers, weak bonding, and unstable structure.
-
Edge cracking during cutting: due to uneven fiber distribution and loose structure.
-
Delamination after bending: from insufficient toughness and weak interlayer bonding.
These issues result from material structure and forming quality—not from installation errors.
CCEWOOL® refractory ceramic fiber paper overcomes these weaknesses through optimized materials and forming technology, achieving high flexibility and strong tear resistance.
Why CCEWOOL® Refractory Ceramic Fiber Paper Has Better Tear Resistance
Optimized Fiber Structure: High-Speed Fiberizing for Stronger Toughness
CCEWOOL® refractory ceramic fiber paper uses high-speed centrifugal fiberizing, producing longer continuous fibers with fewer short fibers and coarse shots. This provides:
-
A stronger long-fiber skeleton: long fibers interlock to create a dense, continuous network without weak points.
-
Higher tensile toughness: long fibers require more energy to break and allow greater sliding distance, improving performance during bending, pulling, and installation.
This long-fiber network significantly increases tensile strength (ASTM C892), preventing tearing, powdering, and delamination.
Uniform Structure: High-Consistency Wet-Forming Process
CCEWOOL® refractory ceramic fiber paper wet-forming ensures full fiber dispersion before deposition, producing a dense and uniform sheet.
Key benefits:
-
No weak zones: stress is evenly distributed, reducing tear initiation points.
-
Strong interlayer bonding: wet deposition eliminates internal lamination interfaces, allowing clean cuts and crack-free bending.
Intelligent Deep-Drying: Stronger Toughness, No Hidden Cracks
CCEWOOL® uses an intelligent deep-layer drying system that dries the fiber paper uniformly from the inside out, preventing the internal stresses caused by traditional “surface-dry but inner-wet” processes. This ensures that CCEWOOL® refractory ceramic fiber paper does not crack when bent, does not crush under pressure, and maintains tight, clean edges during cutting without tearing. Uniform drying is the key to achieving ceramic fiber paper that resists cracking during processing and use.
Patented Intelligent Quality Inspection: Consistent Strength in Every Roll
To ensure consistent tear resistance in every batch, CCEWOOL® refractory ceramic fiber paper uses its self-developed Fiber Micro-defect Detection System Based on Image Recognition Technology V1.0 . The system monitors fiber length, orientation, uniformity, shot content, thickness, density, and forming consistency in real time, and automatically adjusts process parameters when needed. This closed-loop control keeps the tensile strength of each roll highly consistent and eliminates the missed defects and errors common with manual inspection, removing potential tear-risk points at the source.
Whether used in high-temperature gaskets, complex shapes, furnace door seals, or on-site installation, CCEWOOL® refractory ceramic fiber paper provides superior tear resistance, stable structure, and longer service life.
