Microporous Insulation Products
Microporous insulation products are high-efficiency thermal insulators made by pressing nanophase silica dioxide with additives. The nanostructure creates tiny pores that minimize heat transfer, enhancing the material’s insulation performance.
Manufactured through a specialized dry pressing process, these products are lightweight yet durable, offering superior thermal efficiency in high-temperature environments such as industrial furnaces and kilns. This method ensures a robust material capable of withstanding extreme conditions while providing excellent energy-saving benefits.
Additives for Microporous Board

Due to their special nanoporous structure and the synergistic effect of various additives, microporous insulation product can significantly inhibit heat transfer, convection, and radiation across different temperature ranges.
As a result, they outperform traditional insulation materials like mineral wool, perlite, insulating bricks, calcium silicate, and ceramic fibers, and even surpass products like aerogel felts. In most temperature ranges, the thermal conductivity of microporous insulation product is even lower than that of static air
Thermal Insulation Principle
Microporous insulation materials excel in thermal insulation due to their nanoscopic structure, effectively reducing heat transmission via conduction, convection, and radiation.
- Their tiny particle size minimizes contact area, thereby significantly lowering heat transfer through conduction.
- The nanoporous structure, with pore diameters around 20nm, traps gas molecules, virtually eliminating internal convection.
- Additionally, incorporating anti-infrared powders blocks and reflects infrared radiation, further reducing heat transfer, especially at high temperatures.
This combination of properties makes microporous materials exceptionally efficient for thermal insulation.
