Our ceramic fiber paper is available in three precision-engineered temperature grades, each optimized for specific heat intensity:
- 1260℃ (2300℉): Standard-grade for medium-high heat applications (e.g., industrial ovens, boiler insulation).
- 1400℃ (2550℉): High-alumina grade for extreme heat environments (e.g., kiln linings, metal smelting equipment).
- 1430℃ (2600℉): Zirconia-enhanced grade for ultra-high heat and corrosion resistance (e.g., chemical reactors, aerospace testing furnaces).
Beyond temperature versatility, it offers flexible dimensional options: thickness from 0.5mm (ultra-thin for precision gaskets) to 12mm (heavy-duty insulation), minimum width customizable to 50mm, 100mm, or other specifications. We also produce custom-shaped components and gaskets tailored to irregular equipment profiles—ideal for sealing gaps in complex industrial setups.
Ceramic Fiber Paper Premium Raw Material & Impurity Control
The foundation of our ceramic fiber paper’s performance lies in strict raw material management, ensuring low thermal shrinkage and long-term heat resistance:
- We use high-purity ceramic fiber cotton as the base material, with impurities reduced to less than 1% through multi-stage purification. Excess impurities are a leading cause of grain coarsening, increased linear shrinkage, and shortened service life—our rigorous control eliminates this risk.
- The ultra-pure composition results in a bright white appearance and exceptional stability: linear shrinkage is less than 2% at 1200℃, ensuring structural integrity even after prolonged high-temperature exposure.
- Imported high-speed centrifuges (11,000 RPM) maximize fiber formation rate, producing paper with uniform thickness, slag ball content below 10%, and superior flatness. Slag ball content directly impacts thermal conductivity—our low-slag design delivers a mere 0.12 W/mK at 1000℃, outperforming conventional insulation materials.
We refine traditional wet-forming technology with enhanced slag removal and automated drying, ensuring consistent quality and performance:
- Wet-forming process distributes fibers uniformly, creating a non-layered structure with excellent elasticity and mechanical processability. The paper resists tearing and bending, adapting to complex installation requirements.
- Fully automated drying systems enable faster, more thorough, and uniform drying—resulting in a product with tensile strength exceeding 0.4MPa, high tear resistance, and robust thermal shock stability.
- Our product line extends beyond standard grades to include flame-retardant ceramic fiber paper and expandable ceramic fiber paper, addressing specialized needs like fire protection and dynamic sealing.
Every batch of Highland Refractory® Ceramic Fiber Paper undergoes rigorous quality checks to ensure reliability for industrial use:
- Dedicated inspectors oversee each production stage, with comprehensive test reports provided before shipment—validating key metrics like thermal conductivity, shrinkage, and tensile strength.
- We accept third-party inspections (e.g., SGS, BV) to verify compliance with international standards, giving you full confidence in product quality.
- Production adheres to ISO 9000 quality management system standards, ensuring consistency across batches.
- Each roll is weighed before packaging to guarantee actual weight exceeds theoretical weight, eliminating shortages.
- Packaging consists of 5-ply kraft paper outer cartons and moisture-proof plastic inner bags, ensuring product integrity during long-distance transportation.
With a thermal conductivity of just 0.12 W/mK at 1000℃, our ceramic fiber paper minimizes heat transfer, reducing energy consumption in furnaces, boilers, and high-temperature equipment. Its low density (120-200 kg/m³) also reduces structural load, making it ideal for lightweight insulation needs.
Low impurity content (<1%) and advanced fiber formation technology ensure minimal thermal shrinkage (<2% at 1200℃) and resistance to thermal shock. It maintains structural integrity through repeated heating-cooling cycles, extending service life and reducing replacement frequency.
Tensile strength exceeding 0.4MPa and excellent tear resistance allow for easy cutting, punching, and shaping—even for ultra-thin grades (0.5mm). It adapts to irregular surfaces and tight spaces, making it perfect for custom gaskets and sealing applications.
We offer full customization for thickness, width, shape, and special treatments (e.g., impregnated coatings to eliminate bubbles). Whether you need small precision gaskets or large-format insulation sheets, we tailor the product to your exact requirements.
Our ceramic fiber paper is non-combustible at 1000℃ and features high tear resistance, making it ideal for:
- Alloy splash protection in metallurgy.
- Surface insulation for heat-resistant plates.
- Fireproof materials in construction and industrial safety.
- Electrical insulation (after impregnated coating) for high-temperature electrical components.
- Industrial anti-corrosion insulation in chemical plants and refineries.
When combined with glass fiber, it forms high-efficiency air filter paper with low air resistance, high filtration efficiency, high-temperature resistance (up to 1430℃), corrosion resistance, and environmental safety (non-toxic). Key uses include:
- Air purification in large-scale integrated circuits, electronics, and instrumentation industries.
- Pharmaceutical and biotech manufacturing (sterile air filtration).
- Defense industry, subway, and civil defense construction (toxic fume and smoke particle filtration).
- Food processing (clean air supply) and medical applications (blood and biological fluid filtration).
With excellent mechanical processability and customizability, our ceramic fiber paper is crafted into gaskets and irregular components for:
- Thermal insulation and sealing in furnaces, kilns, and boilers.
- Sealing gaps in high-temperature pipelines and valves.
- Precision sealing in aerospace testing equipment and chemical reactors.
