Nano Microporous Insulation Board | Ultra-Low Thermal Conductivity High-Temperature Insulation Panel
Product Overview
Nano Microporous Insulation Board is a high-efficiency insulation panel built around a nano-scale closed microporous structure. The material blocks the three heat transfer pathways-solid conduction, gas convection and thermal radiation-inside a thin, lightweight sheet. Compared with ceramic fiber board, calcium silicate board and conventional refractory insulation, it delivers a much lower thermal conductivity in the same installation thickness, which helps reduce outer surface temperature and cut heat loss from industrial equipment. It is an ideal upgrade for plants that need thinner insulation layers without sacrificing thermal performance.
The board is produced from high-purity inorganic raw materials through precision batching, high-pressure forming and controlled curing. Its internal structure remains compact and uniform after long-term high-temperature operation and repeated thermal cycling. The panel does not shrink, deform, pulverize or lose insulation efficiency, making it a durable choice for energy-saving retrofits of high-temperature kilns, furnaces and thermal systems.
Key Features
Ultra-Low Thermal Conductivity: the closed microporous matrix greatly restricts heat transfer, outperforming traditional refractory insulation materials at equivalent thickness.
Lightweight and Space-Saving: low bulk density allows a thinner insulation layer, which reduces equipment load and frees internal working space.
Stable High-Temperature Performance: special forming and curing processes keep the structure intact under continuous high heat and thermal shock.
Good Mechanical Strength: high-pressure integrated forming provides adequate compression resistance for stacking, handling and on-site installation.
Flexible Cutting and Shaping: the panel can be cut, drilled or polished on site to fit flat, curved and irregular equipment surfaces.

Application Scenarios
This panel is widely used for lining insulation, backup layers and energy-saving upgrades in industrial kilns, tunnel kilns, metallurgical furnaces, boiler systems, high-temperature flues and chemical reactors. It also serves precision thermal protection in aerospace support systems and new energy thermal equipment where thin yet efficient insulation is required.
Factory & Service Advantages
Huaci is an export-oriented factory specializing in the mass production and custom supply of rigid microporous insulation panels. The whole production chain, from raw material batching and particle homogenization to high-pressure forming and constant-temperature curing, runs on automatic computer-controlled lines. Every batch is digitally monitored to keep density, microporous structure and thermal conductivity consistent. We operate a full-process ERP traceability system covering incoming inspection, in-process checks, finished-product testing, warehousing and export packaging. Samples, trial orders, bulk orders and customized sizes are all supported, with stable lead times and palletized export packaging for long-distance ocean freight.
FAQ
Q: How is this panel different from a conventional ceramic fiber board?
A: The insulation works through a closed microporous structure instead of a fibrous network. Because the pores are smaller than the mean free path of air molecules, gas conduction inside the panel is strongly suppressed. Thermal conductivity therefore stays below 0.020 W/m·K at 200°C, and a thin layer can replace a much thicker fiber board in the same equipment.
Q: What is the maximum working temperature, and how do I choose a grade?
A: Standard grades serve up to 650°C, while high-temperature grades reach 1000–1050°C. Select the grade from the actual hot-face temperature plus a safety margin, and keep the interface temperature within the rated limit of the panel.
Q: Can it be cut and fitted on curved or irregular surfaces?
A: Yes. The panel can be cut with a hand saw, drilled and edge-sanded on site. Cut edges should be sealed or covered, and the panel must stay dry during installation, because absorbed moisture raises thermal conductivity.
Q: Does the material contain asbestos or loose fibers?
A: No. It is made from inorganic mineral raw materials without asbestos. Normal dust protection is still recommended while cutting or sanding.
Q: What about packing, sample orders and lead time?
A: Panels are packed in cartons on fumigation-free pallets, and glass fiber scrim or aluminum foil facing is available. Standard sizes ship from ready stock, while customized sizes are usually produced within two to three weeks.
