Ceramic Fiber Rope Cloth Tape
Ceramic Fiber Rope Cloth Tape are high-temperature products manufactured by spinning, twisting, braiding, or weaving high-purity Aluminum Silicate Fibers (RCF) into various flexible, fabric-like forms. They are essential for applications requiring a flexible, compressible, and reliable high-temperature seal or thermal wrap where rigid materials cannot be used. They often contain a small amount of carrier fiber (like fiberglass or metal wire) for improved handling strength.
Main Chemical Compositions & Categories
The core material is RCF, which dictates the MST. Carrier fibers are added for mechanical strength, but may reduce the MST slightly.
| ADDITIVE | FUNCTION | MAX SERVICE T (Approx.) |
| Fiberglass Carrier | Low-cost strength enhancement | 550°C (RCF itself remains) |
| Inconel Wire | Maximum mechanical strength and erosion resistance | 1000°C (1832F) |
Key Forms and Applications
| PRODUCT FORM | CONSTRUCTION | PRIMARY APPLICATION |
| Rope (Twisted/Braided) | Round or square cross-section, dense | Gasketing for furnace doors and lids, boiler sealing. |
| Cloth (Woven Fabric) | Flexible sheet material | Curtains, protective blankets, expansion joint covers. |
| Tape (Woven/Knitted) | Narrow, flat strip | Pipe wrapping, heat tracing insulation, small seals. |
Ceramic Fiber Rope Cloth Tape
Advantages and Key Characteristics
Ceramic Fiber Textiles maintain the excellent thermal insulation properties of RCF while providing the flexibility necessary for sealing complex or moving parts.
- Conformity and Sealing: Their flexible nature allows them to conform to uneven surfaces, making them highly effective as compressible gaskets for furnace doors and lids, ensuring a tight seal that minimizes heat loss and prevents air infiltration/outgassing.
- Mechanical Reinforcement: The incorporation of metallic wires (e.g., Inconel) significantly increases the tensile strength and resistance to abrasion at high temperatures, which is critical for door seals and applications with mechanical movement.
- Thermal Shielding: Cloth and tape are easily deployed as flexible thermal barriers (e.g., curtains) to partition heat zones or protect sensitive components from radiant heat.
- Asbestos Replacement: These materials serve as the primary, safe, and high-performance replacement for traditional asbestos-based textiles in high-temperature gasketing and wrapping applications.
Typical Industries and Applications
These products are used wherever a flexible, high-temperature thermal barrier is needed:
- Furnace Maintenance: Rope is the standard material for sealing furnace and kiln doors, flue joints, and peep hole plugs.
- Piping and Ductwork: Tape is used for pipe wrapping to insulate small-diameter runs, and cloth is used for flexible expansion joint covers on large ducts.
- Metallurgy/Welding: Cloth is used for stress-relieving blankets or as protective covers to shield nearby equipment during hot work.
- Ovens and Dryers: Gaskets and seals for conveyor oven lids and continuous processing equipment.
Key Data Sheet Properties to Consider
Selection is highly dependent on the required mechanical strength and maximum service temperature:
- Maximum Service Temperature (MST): CRITICAL VALUE. Must be checked, specifically for the temperature limit of the carrier fiber or wire (which often limits the maximum use T).
- Density/Construction: Rope and tape are specified by their cross-section (diameter/width) and construction (twisted is soft, braided is firmer) to achieve the correct level of sealing compression.
- Tensile Strength: High tensile strength (especially with wire reinforcement) ensures the textile does not snap or fray during installation or service.
Technical Guidance: When used for sealing, the rope or gasket should be slightly larger than the gap to ensure it is compressed during installation, creating a tight, resilient seal. When using cloth or tape with a fiberglass carrier, be aware that the fiberglass will burn out around 550°C, leading to a temporary reduction in mechanical strength before the RCF fibers fully take the load.

❓ Frequently Asked Questions (FAQ)
Question | Elaborated Answer |
Q: What is the Refractoriness Under Load (RUL) of your refractories? | A: Refractoriness Under Load (RUL) is a critical property that defines the maximum temperature our materials can withstand while under compressive stress before deforming (softening). Since we offer a wide range of materials—from Alumina-Silicate Bricks to high-performance Silicon Carbide Bricks—the RUL varies significantly. For specific product data, please refer to the product data sheet or submit a quote request for the material you are interested in. |
Q: Where are the Rabatec refractories and materials produced? | A: Our products are primarily sourced from specialized manufacturing plants in China. Crucially, these facilities have all undergone rigorous audits and achieved comprehensive ISO certifications (Quality, Environment, and Safety), ensuring that production adheres to the highest global standards for consistency and performance. |
Q: What refractory materials does the company offer? | A: We supply a comprehensive portfolio of advanced refractory solutions, including: Shaped Products: Alumina & Silica Bricks, Basic & Specialized Bricks (e.g., Magnesia), SiC & Structural Ceramics, and Precast Shapes. Monolithic Products: Refractory Castables, Mixes & Mortars. Insulation: Insulation Fibre and High-Performance Insulation Products. |
Q: How should I choose the appropriate refractory material for my application? | A: Selecting the correct refractory is paramount to process efficiency. The choice depends on three key factors: 1. Operating Environment: Maximum process temperature and thermal cycling (shock). 2. Chemical Attack: Type of slag, molten metal, or corrosive gas being handled (acidic, neutral, or basic). 3. Mechanical Stress: Abrasion, erosion, and static load requirements. We recommend utilizing our detailed refractory solutions service to consult with our engineers for an optimized, application-specific recommendation. |
Q: Which monolithic material should I choose when patching an existing lining? | A: For patching and minor repairs, the ideal monolithic material depends on the parent lining material, the patching depth, and the need for a rapid return to service. Common choices include: Refractory Mortars & Mixes (for minor joints/surfaces) or Plastic Refractories (for areas requiring physical compaction). Always choose a patch material chemically compatible with the existing lining to ensure proper bonding and service life. |
Q: Can I receive product samples before placing a major order? | A: Yes. We gladly provide product samples for your internal testing and validation purposes. This ensures you can confirm the quality, composition, and fit of the material—such as our Refractory Castables or Alumina-Silicate Bricks—in your specific operational environment before committing to a bulk purchase. |
