Microporous board is a high-performance thermal insulation material designed for use in high-temperature industrial environments. It is widely recognized for its ultra-low thermal conductivity, lightweight structure, and excellent thermal stability. These properties make it one of the most efficient and space-saving insulation solutions available today.
Microporous boards are made from a blend of:
Fumed silica (the main insulating component)
Opacifiers (to block radiant heat)
Reinforcing fibers (to improve mechanical strength)
This combination creates a dense network of microscopic pores, each smaller than the free path of air molecules. This structure effectively reduces all three forms of heat transfer: conduction, convection, and radiation.
Microporous insulation can achieve thermal conductivity as low as 0.020–0.030 W/m·K, significantly lower than traditional materials like calcium silicate or ceramic fiber.
These boards can operate continuously at temperatures up to 1000°C, depending on the grade.
Due to their superior insulation performance, microporous boards require less thickness to achieve the same thermal resistance—ideal for applications where space is limited.
Microporous boards are typically lightweight, with densities between 200–400 kg/m³, making installation and handling easier.
Microporous boards are asbestos-free, non-combustible, and compliant with international safety and environmental regulations.
Microporous insulation boards are used across various industries that demand high-performance heat insulation:
Rotary kilns (backup insulation)
Industrial furnaces
Petrochemical reactors
Battery thermal protection
Power plants and high-efficiency boilers
Their consistent performance in harsh environments helps improve thermal efficiency, extend equipment lifespan, and reduce energy costs.
If you’re looking for maximum insulation performance in a compact and safe form, microporous boards are an ideal choice. While the initial cost may be higher, their energy savings, space efficiency, and durability provide exceptional long-term value.
