Explore our foundational range of high-efficiency insulation options, manufactured under rigorous quality control standards.
Microporous insulation represents the absolute frontier of thermal barrier technology. Engineered at the nanometer scale, these materials utilize the Knudsen Effect to reduce thermal conductivity below that of still air. By compressing fumed silica particles alongside specialized infrared opacifiers and structure-reinforcing fibers, manufacturers create an internal pore structure averaging less than 20 nanometers. This structural constraint limits the mean free path of gas molecules, effectively shutting down gaseous conduction and radiant heat transfer.
Standard fibrous or cellular insulations fail at elevated temperatures due to exponential radiant heat loss. In contrast, microporous matrices integrate reflective opacifiers that block infrared radiation. Consequently, at 800°C to 1000°C, microporous structures exhibit thermal conductivity ratings up to four times lower than traditional ceramic fiber blankets, allowing system engineers to significantly downsize thermal barrier layers.
For global OEMs, procuring high-performance materials involves managing cost risks alongside lead times. Modern Chinese factories have successfully shifted from high-volume manufacturing to advanced technological engineering. By utilizing localized access to premium raw fumed silica and employing automated, dry-press vacuum lines, these plants maintain cost-competitiveness without sacrificing structural tolerances. The integration of precision manufacturing with robust shipping logistics in hubs like Nanchong and Shenzhen guarantees consistent production scale and rapid worldwide shipping.
Global operations demand compliance with rigorous standards including ASTM C1676, ISO 9001, RoHS, and REACH. High-performance microporous and vacuum insulation panels (VIPs) must maintain their insulating values over decades. To support this, leading factories offer specialized engineering assistance, structural modeling, and thermal testing to ensure materials seamlessly integrate into critical assemblies, such as EV battery cells or fireproof building facades.

Technical answers to common questions about fumed silica VIPs and high-performance microporous insulation.
At ambient pressure and room temperature, microporous fumed silica insulation exhibits thermal conductivity values around 0.018 to 0.020 W/m·K. Under vacuum encapsulation (as seen in VIPs), this value can drop to between 0.004 and 0.006 W/m·K.
Fumed silica cores have a smaller pore structure (around 10-20 nm) compared to glass fiber cores. Even if the vacuum barrier is compromised, fumed silica retains a thermal conductivity of approximately 0.020 W/m·K, whereas compromised glass fiber cores quickly rise to over 0.035 W/m·K.
No. Vacuum insulation panels cannot be cut, drilled, or physically altered, as puncturing the outer envelope will release the vacuum and reduce the panel's insulating performance. Exact sizing must be specified during the manufacturing phase.
When correctly installed inside a protective layer (such as structural architectural walls or appliance casings), our fumed silica VIPs are designed to maintain high thermal performance for 30 to 50 years.
Our microporous materials conform to standards including ASTM C1676, and meet RoHS, REACH, and UL94-V0 fire safety requirements.
This relationship gives Zerothermo access to advanced industrial vacuum engineering facilities, testing equipment, and a robust raw material supply chain.
