TT core is a high-performance microporous insulation panel specifically engineered for use in Vacuum Insulation Panels (VIPs). Its exceptional thermal efficiency and space-saving capability are driven by an ultra-low thermal conductivity. The optimized microporous structure, enhanced with opacifiers, suppresses all three modes of heat transfer — conduction, convection, and radiation — pushing thermal performance close to their physical limits under atmospheric pressure.
In precision-controlled environments, cold chain logistics, and commercial refrigeration, space is revenue and energy is cost. Traditional insulation often requires impractical thickness to meet modern performance standards, compromising valuable capacity and operational efficiency.
This is the core challenge that TT core solves. By harnessing the exceptional properties of microporous silica, our technology enables VIPs to deliver radically superior thermal resistance in a fraction of the space. This means you can design thinner cabinet walls for greater storage volume, achieve longer, more stable storage cycles with less energy, and build systems engineered for reliable performance measured in decades, not years.
Our advanced materials are not just components; they are the foundation for building smarter, more sustainable, and more profitable cold environments.
Our TT core series microporous insulation panels are the engineered heart of high-performance Vacuum Insulation Panels (VIPs). Designed for demanding cold insulation applications, they deliver unmatched thermal efficiency and reliability.
Formulated with advanced microporous technology, these panels enable VIPs to achieve an initial thermal conductivity as low as 0.004 W/(m•K). With over ten specialized material formulations, we tailor solutions to meet specific thermal, mechanical, and environmental requirements in cold storage, refrigeration, and cryogenic systems.
To ensure seamless integration into your production, we provide precision cutting and wrapping services. For large-volume projects, we offer custom mold design to optimize material yield and minimize waste—helping you enhance manufacturing efficiency while achieving exceptional insulation performance.
While the high-barrier envelope preserves the vacuum, the core material fundamentally determines VIP performance and longevity. As internal pressure gradually increases over time, the degradation rate depends entirely on the core.
Our microporous silica cores are specifically engineered for optimal long-term stability under these conditions (see performance chart). This intrinsic stability, paired with a high-barrier foil (typically limiting pressure rise to <0.5 mbar/year*), ensures the most reliable and durable insulation solution available.
Rate varies with ambient temperature.
| Core material | Initial pressure | Pressure for 8 mW/m.K |
| Glass fiber | 0.01 mbar | 1.0 mbar |
| Fumed silica | 0.5 mbar | 100 mbar |
As a core material specialist, we also supply complete VIPs featuring our microporous silica core. Each panel is encapsulated in an ultra-high-barrier film and vacuum-sealed, delivering exceptional and consistent thermal performance.
These panels offer key advantages: optimized space and thickness, extended storage cycles, and proven long-term durability. They are self-supporting, pressure-resistant, and easy to install. Through specialized processing and innovative formulations, our VIPs achieve an outstanding and stable thermal resistance (R-value).

TT core is a microporous insulation panel optimized for use in Vacuum Insulation Panels (VIPs). The Unicorn VIP core material features a very low density, which results in the lowest possible thermal conductivity, typically around 4 mW/m K. Despite its extremely low density, the panels are easy to handle.
Unicorn offers customized cutting services. For large volume orders, we can utilize customized pressing molds to minimize cutting waste. As an option, the core can be wrapped in non-woven fabric to reduce dust during the evacuation process.
Typical applications:

TT core eco is a microporous insulation panel with a cambered edge designed for use in Vacuum Insulation Panels (VIPs). TT core eco can be produced at very low densities, which enables it to achieve even lower thermal conductivities than a standard VIP (<4 mW/m K).
The external non-woven fabric provides a dust-proof yet air-permeable cover around the microporous core. As a result, the product can be directly incorporated into your manufacturing process before drying and vacuuming.

TT coolvac is a high-performance Vacuum Insulation Panel based on a fumed silica microporous core material – TT core series products. The core is sealed in a high-barrier multilayer foil, which contributes to extremely low conductivity (0.004 W/m K) and a long service life of up to 50 years. TT coolvac offers straight edges and best-in-class stability, ensuring quick and easy installation while minimizing damage-related loss.
In comparison to other core materials VIPs, TT coolvac demonstrates a very low volume increase due to its minimal expansion characteristics. It also maintains a very low initial lambda under normal pressure, enabling cool box manufacturers to achieve very stable and long-lasting service performance during transportation.
