Microporous insulation structures utilize the physics of the Knudsen Effect to deliver unprecedented thermal resistance. By manufacturing a matrix of silica structures with pore sizes averaging between 20 to 100 nanometers—well below the mean free path of air molecules at standard atmospheric pressure—the transmission of thermal energy via gaseous convection is fundamentally minimized.
Traditional refractory materials such as mineral wool, ceramic fiber, or calcium silicate rely on trapping air in large macro-spaces. At extreme operating temperatures exceeding 800°C, high-velocity molecular collisions within these large pockets act as bridges for thermal transport. Nano-microporous insulation panels disrupt this pathway completely, achieving thermal conductivity values as low as 0.018 W/(m·K), which is significantly lower than that of still air.
For engineering applications demanding strict compliance with fire protection directives (such as EN 13501-1 Class A1 non-combustibility and UL 94 V-0 requirements), fumed silica-based microporous boards present an impenetrable thermal shield. These structures are structurally reinforced with inorganic opacifiers to reflect infrared radiation, ensuring minimal thermal degradation and physical contraction over thousands of heating cycles.

Under international safety standards like ECE R100, electric vehicles require a multi-minute delay in cell-to-cell thermal propagation. Custom thin-profile microporous thermal blankets provide high breakdown resistance in tight spaces.
In architecture and maritime design, space is premium real estate. Reducing wall insulation thickness while maintaining structural R-values increases usable floor layout, driving demand for vacuum integrated panels.
Carbon neutrality goals require manufacturing facilities to minimize energy dissipation. Microporous backings in industrial ovens and iron smelters save up to 40% in radiant heat loss compared to conventional fibers.

Explore ParametersAs a key subsidiary of the prestigious CBVAC Group, Zerothermo Technology Co., Ltd. is recognized as a leading national high-tech enterprise. Our state-of-the-art production base located in Nanchong City, Sichuan Province, stands as one of China's most comprehensive and advanced manufacturing centers for vacuum technology and nano-thermal application products.
We combine academic vacuum science with rigorous engineering production to manufacture highly reliable microporous boards, VIPs (Vacuum Insulation Panels), and custom high-temperature barriers. Our strict quality system controls ensure every square meter conforms to demanding industrial specifications, providing reliable solutions globally.
Supporting our insulation lines is our precision metallurgical fabrication division. We design and deliver custom component profiles according to client-submitted CAD files and strict operating tolerances:
Custom sizes exceeding ANSI/ASME/DIN standard scopes, produced according to custom parameters.
Square, oval, asymmetric, and micro-precision flanges, including large-scale diameters exceeding 60 inches.
High leak-tightness finishes, ideal for integration within advanced industrial furnace chambers.
Every batch of fumed silica raw material undergoes verification tests. We maintain tight pore distributions to ensure zero hotspots in safety-critical thermal environments.
We customize physical properties—from high-density load-bearing boards to flexible wraps—meeting your mechanical and thermodynamic design constraints.
Our computerized dry-press molding lines support continuous output, fulfilling large-scale structural project schedules without supply-chain bottlenecks.
We design specialized protective shipping packaging to keep moisture-sensitive microporous panels safe, ensuring they arrive dry and structurally intact.
We work closely with your design and quality teams from raw prototypes to final certifications, ensuring reliable integration at every step.
By utilizing our advanced fumed silica vacuum insulation panels (VIPs) and high-temperature microporous boards, we provide high-efficiency thermal insulation solutions across multiple demanding sectors.
In the Pharmaceutical Cold Chain, we protect critical vaccines and biological samples for long periods. In Architecture, we supply energy-saving, thin insulation boards that reduce carbon footprints. For High-Temperature Industries, our microporous boards act as back-up insulation in kilns and smelters, protecting structures, reducing thermal losses, and lowering energy costs.

Analyzing how nano-structured materials outperform traditional fiber systems in industrial and petrochemical applications.
Our standard nano-microporous boards are rated for continuous use at temperatures up to 1000°C, with peak classification limits reaching 1100°C. For applications above these levels, we can modify the core opacifiers and fibers to optimize stability.
Unprotected fumed silica is naturally hydrophilic. To prevent water absorption, we offer hydrophobized cores and protective barrier coverings (such as heat-sealed PE/PET films or aluminum foils) to maintain thermal performance in humid or wet environments.
When installed correctly according to our engineering guidelines, our fumed silica VIPs are designed for a service life exceeding 30 to 50 years. This longevity is achieved through multi-layered barrier wraps and integrated gas getters that absorb internal moisture and outgassed molecules over time.
Rigid, unencapsulated microporous boards can be trimmed using standard woodworking tools (with dust extraction). However, Vacuum Insulation Panels (VIPs) must never be cut or punctured on-site, as losing the internal vacuum will reduce their thermal resistance to standard atmosphere levels.
Whether you need customized thicknesses for EV battery enclosures or large-volume shipments of structural building insulation, our technical engineers are here to support your project requirements.
