Soluble Fiber Board / Paper
Soluble Fiber (or Low Bio-Persistence) products are high-temperature insulation materials engineered to offer the excellent thermal performance of traditional ceramic fiber, while being chemically designed to dissolve quickly in the human body’s physiological fluids. This significantly reduces the potential health risk associated with fiber inhalation, making them the preferred choice in regions with strict safety regulations.
Soluble Fiber Board is a rigid, self-supporting insulation board made by vacuum-forming LBP fibers with an inorganic binder. It provides high-temperature insulation combined with structural stability and high compressive strength.
Key Features and Use
| PROPERTY | DESCRIPTION | PRIMARY ADVANTAGE |
| Form | Rigid, self-supporting panel | Used where mechanical strength and rigidity are required. |
| Density | HIGH | Offers good resistance to light mechanical load and high-velocity gas erosion. |
| Applications | Furnace doors, rigid baffles, burner blocks,
and backup insulation for dense linings operating below 1200°C. |
Technical Note
The density of the board (higher than blankets) helps further minimize fiber release under mechanical stress, enhancing the safety profile for maintenance workers.
Soluble Fiber Paper is a very thin, flexible insulation material produced using a modified papermaking process. It is used for sealing, wrapping, and precision gasketing in areas with minimal clearance.
Key Features and Use
| PROPERTY | DESCRIPTION | PRIMARY ADVANTAGE |
| Form | Thin, flexible sheet (0.5 mm to 5 mm) | Excellent conformity and precision sealing in tight spaces. |
| Flexibility | EXCELLENT | Can be easily die-cut, wrapped, and bent without breaking. |
| Applications | High-temperature gaskets for flanges and joints, thermal wrapping of heating elements, and as a protective, separating layer in kilns. |
Technical Note
Paper has a negligible thermal mass, making it ideal for creating an immediate thermal break without adding significant heat-up time to the assembly.
Performance and Technical Guidance
Composition and Temperature Limits
The MST of LBP fibers is typically lower than the highest-grade RCF but is sufficient for a wide range of industrial applications.
- Composition: CaO / MgO / SiO2 / Al2O3 blend.
- Maximum Service Temperature (MST): Typically 1200°C (2192 F).
Primary Advantage: Health and Safety
The primary reason for selecting these products over standard RCF is the Low Bio-Persistence characteristic. Fibers are engineered to be chemically soluble, meaning they break down rapidly and are cleared from the lungs, adhering to modern health standards for refractory mineral fibers.
Selection Guidance
- Choose Board when you require the thermal insulation of fiber plus compressive strength or need a rigid, self-supporting lining (e.g., doors).
- Choose Paper when you require a thin, flexible gasket or wrapping material for tight clearances and complex shapes (e.g., flange sealing).

❓ 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. |
Q: Do you provide certifications to verify material quality? | A: Absolutely. We provide product-related inspection certificates and quality assurance documentation upon request. This verifies that your order has passed all internal quality control checks and meets the required material specifications and industry standards. |
Q: What measures are taken for product protection during transport? | A: We ensure quick, reliable transport by using robust, industrial packaging that strictly follows industry standards. This includes high-strength palletization, heavy-duty strapping, and weather-resistant wrapping to protect fragile items like bricks and mixes from corner chipping, mechanical damage, and moisture during transit. |
