Description


1. Product Overview


Sanhe's core product, the low-dimensional Nano Insulation Board — also known as Microporous Insulation Board — is engineered using advanced nano-microporous technology. Selected low-thermal-conductivity inorganic refractory nano-powders are processed through a patented dry-forming process to create a uniform, dense, low-dimensional nano-microporous structure with a pore diameter below 100 nanometers. 
This unique pore structure restricts the free movement of air molecules, significantly suppressing gaseous heat conduction. Specialized functional additives further block infrared thermal radiation. As a result, the nano insulation board blocks heat transfer across all three mechanisms — conduction, convection, and radiation — delivering insulation performance far beyond conventional refractory materials. 


The product is an ideal replacement for traditional insulation materials such as calcium silicate boards, ceramic fiber blankets/boards, and rock wool. Under high-temperature conditions, it delivers up to 4–5 times better thermal insulation performance, allowing customers to reduce construction thickness, lower installation cost, and achieve a faster return on investment.

3. Product Advantages


  • Ultra-low thermal conductivity: as low as 0.020 W/(m·K) at room temperature and below 0.032 W/(m·K) at 800°C — up to 80% lower than traditional insulation materials.
  • High-temperature resistance: continuous service temperature of 1000–1050°C (model-dependent), with peak resistance up to 1200°C.
  • Dimensional stability: high-temperature linear shrinkage below 2%, maintaining structural integrity without deformation or collapse.
  • Outstanding energy savings: equivalent insulation performance at only 1/5 to 1/3 the thickness of conventional materials — for example, a 25 mm Sanhe nano board achieves the same hot-face-to-cold-face performance (900°C to 97°C) as a 106 mm ceramic fiber board.
  • Environmentally friendly and safe: 100% inorganic composition, free of asbestos and other hazardous substances, with zero toxic gas emission at high temperature.
  • Easy to process and install: can be cut and drilled with standard woodworking tools for convenient on-site installation.
  • Flexible customization: dimensions, density, and thickness can be tailored within a defined range to match each customer's structural design.
  • Quality assured: manufactured under ISO 9001 and ISO 14000 certified management systems; independently tested by SGS for thermal conductivity, specific heat, water absorption, vertical burning, insulation resistance, RoHS, REACH-SVHC and ELV compliance.

6. Frequently Asked Questions


Q1: What is a Nano Insulation Board (Microporous Insulation Board)?

It is a high-performance refractory insulation panel made from low-thermal-conductivity fumed silica nano-powders, formed by a patented dry-press process into a low-dimensional nano-microporous structure (pore diameter <100 nm). This structure suppresses heat conduction, convection, and radiation simultaneously, giving the board insulation performance well beyond conventional refractory materials.

Q2: What is the maximum operating temperature?

Long-term service temperature ranges from 950°C to 1050°C depending on the model (SH400/SH550: ≤1000°C; SH950: 950°C, ; SH1150: 1050°C). Please refer to the technical specification table above for model-specific data.

Q3: How does it compare with ceramic fiber, calcium silicate board, or aerogel?

At equal insulation performance, the nano insulation board requires only 1/5 to 1/3 the thickness of conventional materials. In one documented case, a 25 mm Sanhe nano board achieved the same hot-face/cold-face result (900°C/97°C) as a 106 mm ceramic fiber board.

Q4: What sizes and thicknesses are available?

Standard sizes range from 200×200 mm up to 1000×600 mm and thickness from 1.0 mm to 100 mm, depending on the model. Custom dimensions, density, and thickness can be produced to match your project requirements.

Q5: What packaging do you provide for export shipments?

Boards are encapsulated in POF heat-shrink film, thermoplastic film, aluminum foil, vacuum-packed aluminum foil, or fireproof cloth depending on the model, then packed in cartons or wooden cases suitable for sea and air freight.

Q6: Is the product safe and environmentally compliant?

Yes. The boards are 100% inorganic, asbestos-free, and emit no toxic gases at high temperature. Products are manufactured under ISO 9001 and ISO 14000 certified systems and have been independently tested by SGS for thermal conductivity, RoHS, REACH-SVHC, and ELV compliance.

Q7: Which industries use Sanhe nano insulation boards?

Cement, steel and metallurgy, non-ferrous metal (aluminum electrolysis), petrochemical, ceramics, glass, power generation, shipbuilding, new energy/battery energy storage. 

Q8: Can the product be customized for our specific project?

Yes. Sanhe offers sample development and testing, thermal simulation, insulation system design, and process customization to match your operating temperature, structural constraints, and space requirements.

Compared with conventional materials such as aerogel blankets and foam insulation, our nano microporous insulation delivers ultra-low thermal conductivity, high temperature resistance, and superior thermal stability, making it an ideal solution for battery thermal runaway protection.

Cement Kiln

In the cement industry, beyond the equipment itself, one of the most critical factors is the energy consumption and heat loss of the kiln system. In a typical clinker production line, the rotary kiln operates continuously at temperatures exceeding 1000°C. Heat dissipation from the kiln shell not only wastes energy, but also directly impacts production efficiency and equipment lifespan. In recent years, more and more manufacturers have turned their attention to an advanced insulation material: nano insulation boards/Microporous Insulation Boards.

Aluminum Electrolysis Cell

In modern electrolytic aluminum production, the thermal balance and structural stability of the pot are directly related to energy consumption and pot life. As a high-performance inorganic refractory material, Sanhe vermiculite board has become a key functional layer in the cathode structure of electrolytic aluminum pots due to its high-temperature resistance, low thermal conductivity, and excellent resistance to fluoride corrosion.

Steel Ladle

Nano microporous insulation panels have thermal insulation performance that is 3 to 4 times higher than conventional materials and can withstand high temperatures. They are particularly suitable for thermal insulation in steel equipment, helping achieve energy saving and emission reduction.

Fireplace

In modern home design, a wood-burning or gas fireplace is more than just a source of heat—it’s a centerpiece that creates warmth, comfort, and ambiance. However, with flame temperatures often reaching 600°C to over 1000°C, fire safety and thermal efficiency quickly become top priorities in fireplace design.
