High-Performance Thermal Materials Manufactured in China
Technical Efficacy, Classification, and Thermal Dynamics
In the contemporary landscape of high-performance construction, cold chain logistics, and high-temperature heavy industry, thermal management and fire safety are no longer independent targets. They are interconnected challenges that demand cutting-edge material science solutions. Fireproof insulation panels engineered using nano-microporous and vacuum insulation technology have revolutionized how engineers insulate space-critical environments.
Vacuum Insulation Panels (VIPs) operate on the principle of eliminating gaseous thermal conduction. By evacuating the internal air space of a porous core material (such as fumed silica or fiberglass), the molecular mean free path of any remaining gas is reduced to a level significantly below the pore size of the material. This essentially blocks heat transfer via gas convection and conduction.
For high-temperature applications, nano-microporous panels utilize compressed silica particles to create microscopic voids smaller than the mean free path of air (approximately 70 nanometers at standard pressure). Consequently, even without a complete vacuum, these panels achieve thermal conductivity values lower than still air, all while being constructed from inorganic oxide compounds that are inherently non-combustible (Class A1 rating).
| Material Type | Thermal Conductivity (W/m·K) | Max Operating Temp | Fire Safety Classification | Primary Industry Application |
|---|---|---|---|---|
| Fumed Silica VIPs | 0.004 - 0.006 | 80°C - 100°C | Class A1 / Class B (depending on film) | Cold Chain Logistics, Freezers, Building Envelope |
| Nano Microporous Panels | 0.016 - 0.022 | 1000°C | Class A1 (Non-Combustible) | Elevator Fire Doors, Industrial Kilns, Metallurgy |
| Fiberglass Core VIPs | 0.002 - 0.004 | 120°C | Class B | Domestic Refrigerators, Deep Cold Shipping Box |
| Polyurethane (PU) Foam VIPs | 0.018 - 0.022 | 80°C | Class B1/B2 | Refrigerated Containers, Cold Rooms |

View More +Zerothermo Technology Co., Ltd., a subsidiary of CBVAC Group and a national high-tech enterprise, is headquartered in the Beijing Economic-Technological Development Area with its production base located in Nanchong City, Sichuan Province. This facility stands as one of China's largest comprehensive production centers for vacuum technology application products.
By integrating industrial-scale precision vacuum manufacturing with global standards of R&D, we provide thermal barriers that are thinner, more robust, and significantly safer than traditional alternatives. Our alignment with CBVAC Group grants us unparalleled engineering capacity in vacuum chamber production, thin-film metallization, and outgassing measurement systems.
Special sizes (beyond the range of ANSI/ASME/DIN and other standards) are produced according to customers' drawings or technical parameters.
Square, oval or other special shaped flanges. Oversize/small diameter: such as diameter over 60 inches or micro precision flanges.
Why Industrial Leaders Partner with Zerothermo
Unparalleled standards in vacuum maintenance, thermal conductance verification, and surface finish consistency.
Swift execution of non-standard geometries, specific envelope foils, and performance parameters for key projects.
Mass production facilities that keep unit costs low while ensuring zero compromised quality check points.

Collaborative engineering development, comprehensive validation, and long-term warranty compliance.
Scale, Cost-Efficiency, R&D Integration, and Supply Chain Depth
China is home to the world's most dense raw material network for advanced silicas, fumed silica, and fiberglass core matrices. As a subsidiary of CBVAC Group, Zerothermo leverages high-volume raw material procurement, direct control over membrane lamination, and automated internal vacuuming operations. This vertical structure allows us to cushion global procurement partners from price shocks and guarantees material purity from source to destination.
One of the primary failure modes of VIPs in construction or industrial applications is the mechanical breach of the outer envelope. Chinese research institutes and industrial labs have developed multi-layer composite foils (combining PET, Aluminum, and specialized coatings) that exhibit superior resistance to water vapor transmission and gas permeation. This translates to an operational lifespan exceeding 50 years under standard architectural conditions.
Compared to Western European or American manufacturers, Chinese production facilities deliver similar or superior thermal metrics at a fraction of the capital expenditure. By applying automated manufacturing robotics and utilizing local high-efficiency energy infrastructures in Nanchong, Sichuan, we lower the cost per square meter of R100 (U-value 0.05 W/m²K equivalence) VIP walls, rendering net-zero architecture financially viable.
Our closeness to the CBVAC Group scientific core allows for unique outgassing rate tests, mass-spectrometer leak detections, and customized gas getters development. Gas getters within vacuum chambers are critical to maintaining internal pressures beneath 1 mbar over long time cycles.
