Ceramic Fiber Paper
Ceramic Fiber Paper is a thin, flexible, and lightweight sheet insulation material made from a slurry of high-purity Aluminum Silicate Fibers (RCT), an inorganic binder, and a small amount of organic filler. It is manufactured using a papermaking process. The material is valued for its exceptional flexibility, uniformity, ease of die-cutting, and excellent thermal sealing capabilities in confined and precise spaces.
Main Features and Use
The composition and MST are consistent with other RCF products, but its thin format and low binder content define its specific applications.
| CATEGORY | Al2O3 Content | TYPICAL MST | PRIMARY ADVANTAGE |
| Standard Grade | 45% to 50% | ~1260°C to 2300°C | Flexible, thin gasketing and wrap. |
| High Alumina Grade | 50% to 60% | ~1430°C to 1540°C | Higher MST and less shrinkage. |
Key Performance Metrics
| PROPERTY | TYPICAL PERFORMANCE | MECHANISM OF ADVANTAGE |
| Thickness | VERY THIN | Typically 0.5 mm to 5 mm; allows use in tight clearances. |
| Flexibility | EXCELLENT | Can be easily bent, wrapped, and die-cut for custom shapes. |
| Heat Storage | NEGLIGIBLE | Near-zero thermal mass; provides immediate thermal break. |
| Chemical Inertness | HIGH | Stable in most chemical and corrosive environments. |
Advantages and Key Characteristics
Ceramic Fiber Paper is the solution for creating uniform, thin thermal seals and insulating barriers where bulkier materials like blankets or boards are too thick or inflexible.
- Precision Sealing and Gasketing: The primary use is creating high-temperature gaskets for flanges, removable lids, and seals in tight spaces. It conforms well to irregular surfaces, ensuring a gas-tight seal when compressed.
- Thermal Barrier/Wrap: Used as a lightweight, flexible insulating wrap for pipes, tubes, or heating elements, providing protection without adding significant weight or bulk.
- Electrically Insulating: It maintains high electrical resistivity, making it useful as an insulating layer between heating elements and the furnace casing or insulation.
- Punching and Die-Cutting: The paper format allows for easy, accurate fabrication of complex, custom shapes (e.g., washers, complex flange gaskets) using standard industrial cutting equipment.
Typical Industries and Applications
This product is critical in precise, compact thermal assemblies:
- Appliance and OEM: Used as insulation lining for small batch furnaces, domestic heating units, toasters, and ovens.
- Metallurgy/Foundry: Gaskets for furnace doors, runners, riser tube liners, and hot-top applications.
- Automotive: Used for heat shields, exhaust gaskets, and thermal insulation in high-temperature engine areas.
- Electronics: Insulating liners for induction furnace coils and separating layers for sensitive materials being sintered.
Key Data Sheet Properties to Consider
Selection is based on the required sealing pressure and temperature:
- Maximum Service Temperature (MST): Must be checked, particularly against possible shrinkage.
- Density and Weight: Low values are key to its performance; typically measured in kg/m2 (mass per unit area).
- Tensile Strength: Important for handling and for ensuring the gasket does not tear during installation.
- Binder Content: Lower organic binder content means less smoke/outgassing on initial heat-up, which is crucial for clean atmosphere furnaces.
Technical Guidance: Due to the low organic binder content, the paper will produce a small amount of smoke on the first heat-up as the binder burns out. This should be vented. For applications requiring mechanical reinforcement (e.g., severe vibration), the paper can be backed with a thin layer of foil or encapsulated.

❓ 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. |
