Nano Insulation Board
A Nano Insulation Board is a highly specialized, rigid thermal insulation panel composed primarily of fumed silica with an internal structure defined by nanometer-sized pores. This nanostructure is what gives the board its name and its exceptional thermal performance. By utilizing this structure along with opacifiers (e.g., carbon black or iron oxide), the board achieves the lowest thermal conductivity (k) of any rigid high-temperature material, minimizing all three modes of heat transfer (conduction, convection, and radiation) simultaneously.
Main Components and Structure
The board is engineered for maximum thermal efficiency in minimal thickness.
| COMPONENT | COMPOSITION | FUNCTION |
| Fumed Silica | High-purity SiO2 | Creates the nanoporous structure that blocks gas-phase conduction. |
| Opacifiers | Iron Oxide / Carbon Black | Blocks radiant heat (IR radiation) at high temperatures. |
| Fiber Reinforcement | Inorganic fibers | Provides structural integrity and handling strength. |
| CLASSIFICATION | MAXIMUM SERVICE T | PRIMARY ADVANTAGE |
| Standard Grade | ~950°C to 1000°C | Maximum insulation performance in the smallest possible cross-section. |
| High-Temp Grade | Up to 1200°C | Used for demanding backup insulation in ultra-hot furnaces. |
Key Performance Metrics
| PROPERTY | TYPICAL PERFORMANCE | MECHANISM OF ADVANTAGE |
| Thermal Conductivity (k) | ULTRA LOW | Significantly better than conventional refractory fibers or boards, especially at high T. |
| Thickness Equivalence | Superior | Can replace several inches of conventional insulation with a fraction of the material. |
| Dimensional Stability | EXCELLENT | Rigid and maintains precise dimensions under heat without slumping. |
Nano Insulation Board
Advantages and Key Characteristics
Nano Insulation Boards are a premium solution utilized when there is an absolute need to minimize furnace wall thickness, reduce weight, or when energy conservation is paramount.
- Extreme Space Savings: This is the most compelling reason for selection. The exceptional k value allows for a 50% to 75% reduction in the required insulation thickness compared to materials like Calcium Silicate or Ceramic Fiber. This increases the furnace’s internal working volume and reduces its overall footprint.
- Energy Efficiency: By providing a highly effective thermal break, these boards drastically reduce heat loss and lower the cold-face temperature of the furnace shell. Their low thermal mass also contributes to faster heating and cooling cycles.
- Protection of Equipment: They are commonly used as a highly efficient backup layer to protect less durable, lower-temperature insulation (like mineral wool or CS board) from excessive heat exposure.
Typical Industries and Applications
This material is specialized for high-tech, high-temperature, and mobile applications:
- Metallurgy: Back-up insulation for induction furnaces, ladles, and tundishes where wall thickness is critical to maximizing internal volume.
- Aerospace/Automotive: Insulation for specialized test rigs, portable heat-treating equipment, and small, precise sintering furnaces.
- OEM Equipment: Thin, high-efficiency insulation for appliances, ovens, and dryers where the manufacturer needs low-profile insulation to meet strict surface temperature standards.
Technical Guidance
Nano Insulation Boards are very effective but delicate. They are not suitable for direct hot-face exposure to gas velocity or abrasion. They must be protected by a durable material (like brick, castable, or high-density ceramic fiber board). The panels are often factory-wrapped in a fiberglass cloth or plastic film to contain the fine silica powder; this wrapping must remain intact during installation to ensure both safety and material integrity.

❓ 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. |
