Custom Panel VIP Factory & Factories

In the modern era of thermal management, the search for highly efficient materials is driven by global carbon neutrality goals. Traditional materials such as Polyurethane (PU) and rockwool are hitting their physical limits. The future belongs to Vacuum Insulation Panels (VIPs). As a leading customized panel VIP factory group, we focus on engineering panels with a thermal conductivity ranging between 0.0015 W/m·K and 0.004 W/m·K. This is up to ten times more efficient than conventional materials.

The Physics of Low Thermal Conductivity

Thermal conduction in porous materials occurs via three main routes: solid conduction through the core matrix, gas molecular movement within the pores, and radiative heat transfer. VIPs operate by removing gas molecules from the core structure. By lowering the pressure inside the core, the mean free path of the remaining gas molecules exceeds the average size of the pores (known as the Knudsen Effect). This significantly reduces convective heat transfer.

Core Material Comparison: Fumed Silica vs. Fiberglass

Different applications call for different core structures:

• Fumed Silica Core: Features a pore size of about 10–100 nanometers. This core is highly durable, retains vacuum conditions well, and has a lifespan of 20 to 50 years. It is widely used in construction, refrigeration, and cold chain applications.
• Fiberglass Core: Offers a lower initial thermal conductivity, but features larger pores (1–10 micrometers). As a result, it is more sensitive to moisture and vacuum degradation, making it suitable for shorter-lifecycle applications.

Integrated Raw Material & Manufacturing Ecosystem

Our production base in Nanchong Province places us in a major hub for raw material sourcing. By utilizing a vertically integrated supply chain, we maintain full control over the sourcing of raw fumed silica, high-barrier envelope films, and drying agents. This allows us to offer competitive pricing without compromising on technical quality.

Advanced Quality Control & Testing

Every single VIP produced in our factories undergoes strict quality control tests, including:

• Vacuum Decay Verification: Ensuring the long-term sealing performance of the protective film barrier.
• Thermal Conductivity Testing: Testing the performance of every batch using heat flow meter technology.
• Dimensional Accuracy Inspections: Utilizing automated custom-shaping processes to meet client requirements down to the millimeter.

Reliable Global Supply and Execution

Our factories leverage automated production systems and large-scale manufacturing capacity. This allows us to handle large-volume orders while keeping lead times short. Whether you need standard-sized refrigeration panels or specialized shapes for vehicle batteries, we deliver reliable, high-performance thermal insulation globally.
