II. WHMF Nano Thermal Insulation Core Technology and Product Parameters

1. Nano Triple Thermal Insulation Principle

WHMF full product line uses 7~12nm fumed silica as the core base material, compounded with high-temperature resistant inorganic fibers and SiC/Zr₂O infrared opacifiers, formed at high temperature as an integrated piece, forming a 90% high-porosity nano-microporous structure internally, simultaneously blocking three heat transfer paths:

1. Blocking solid conduction: Ultra-fine nano powder elongates the solid heat transfer path, significantly reducing solid-phase thermal conductivity;

2. Suppressing gas convection: The micropore size is smaller than the mean free path of air molecules, preventing convective heat transfer of air;

3. Blocking infrared radiation: Special opacifiers reflect high-temperature infrared radiation, resulting in extremely low thermal insulation degradation under high-temperature conditions. Under the same operating conditions, thermal insulation performance is 3-4 times that of traditional insulation materials such as rock wool and ceramic fiber.

2. General Core Physical and Chemical Indicators

3. WHMF Five Standardized Product Matrices

To address the different high-temperature, confined, flexible, ultra-thin, and metallurgical special operating conditions across various industries, we have five series to achieve full-scenario coverage:

1. WHMF-41 Nano High-Temperature Insulation Board Rigid standard board, supporting 2.8-meter extra-long one-piece custom sizing, suitable for energy storage prefabricated cabins, factory firewalls, general industrial furnaces and kilns, achieving EI60/EI90/EI120 multi-level fire resistance grading, the most widely used general-purpose model.

2. WHMF-42 Ladle-Dedicated Nano Insulation Board Metallurgical custom formulation, resistant to molten steel thermal shock and low heat storage, used for ladles, tundishes, torpedo cars, and electrolytic aluminum pots, reducing molten metal temperature drop and lowering metallurgical fuel consumption.

3. WHMF-43 Flexible Nano Insulation Board Bendable and flexible structure, suitable for irregularly shaped equipment, high-temperature pipelines, and removable insulation jackets, widely used in petrochemical, boiler, and high-speed train cabin insulation.

4. WHMF-44 Vacuum Nano Insulation Board Extremely low heat capacity and ultra-low thermal conductivity, for aerospace precision equipment, laboratory high-temperature furnaces, and cold-chain medical equipment, where high temperature control precision is required.

5. WHMF-46 Ultra-Thin Nano Insulation Sheet Ultra-thin specifications of 0.8~7mm, with excellent insulation and voltage resistance, specially designed for gaps between new energy vehicle battery cells and energy storage modules, combining thermal insulation, cushioning, and flame retardancy.

4. Six Core Product Advantages

1. Ultra-thin & Space-saving: Only 1/3 the thickness of traditional materials for the same insulation effect, freeing up internal equipment volume and increasing energy storage and battery pack capacity;

2. Stable High-Temperature Performance: Thermal conductivity at 800℃ is only 0.032 W/m·K, with no pulverization or settlement during long-term use;

3. Safe, Long-lasting & Durable: Fully inorganic Class A non-combustible material, corrosion-resistant, resistant to thermal cycling, with a service life far exceeding that of rock wool and ordinary aerogel;

4. Lightweight & Low Load: Density of only 250~400kg/m³, reducing the overall load-bearing of cabins and furnaces;

5. Flexible Customization & Easy Installation: Thickness, length/width, and hardness/softness can all be cut and customized, with an integrated sheet design for simple on-site assembly;
