Fields of application for Stainless Steel Vacuum Insulation Panel

Stainless steel sealed vacuum insulation panels are expected to be used in a variety of industrial fields due to their outstanding thermal insulation performance. We will contribute to the technological innovation of the next generation, especially in the fields of transport and building materials, where energy efficiency and temperature control are required.

Mechanism of Stainless Steel Vacuum Insulation Panel

This material is made by creating a vacuum inside a double-layered stainless steel foil to enhance thermal insulation performance. In addition, a core material is placed inside to seal it in order to maintain its shape.

Realized with High thermal insulation, Long service life, and Nonflammability

Because the interior is a vacuum, the heat conductivity is less than 0.0025 W/m/K*1, which is approximately 10 to 25 times higher than that of conventional heat insulators.

Furthermore, by using stainless materials and applying the vacuum insulation technology for vacuum bottles to create a panel, we made it possible to maintain nonflammability and high thermal insulation properties over a long period of time, something that was not possible with conventional vacuum insulation materials.

This has enabled us to maintain vacuum insulation for a long period of time (more than 30 years)*2, thereby achieving safety through its long service life and nonflammability.

Realized with Surprising Thinness

Equivalent heat insulation effect can be obtained with about 1/10th the thinness of urethane foam

*Thermal resistance R=0.01/0.0025=4.00 ㎡K/W for a prototype of TIVIP with a thickness of 10 mm and size of over 440 mm square,
Thermal resistance R=0.1/0.024=4.16 ㎡K/W for rigid polyurethane foam of a thickness of 100 mm and size of over 440 mm square

*This is an illustration of thickness calculated based on thermal conductivity quoted from the Ministry of Land, Infrastructure, Transport and Tourism’s “Study Policy in the Standard for Labeling and Evaluation Methods (Energy Conservation). Actual thickness may vary depending on product and usage conditions.

For use in the Osaka/Kansai Expo, we sandwich our newly developed Stainless Steel Vacuum Insulation Panel “TIVIP” with Gifu Plastic Industry‘s lightweight and high-strength material, TECCELL, a resin honeycomb panel, to protect TIVIP and create a lightweight and strong insulation unit panel.

By using these heat insulation unit panels in Nippon Express’ transportation packaging tools, such as the “Protect BOX”, high-performance cold storage transportation has become possible. Conventional frozen, refrigerated, and temperature-controlled transportation requires the use of cold and heat storage materials to maintain temperature, but these materials are no longer necessary, resulting in a significant reduction in electricity consumption.

Tiger Corporation collects and recycles stainless steel bottles that are no longer needed at home, regardless of manufacturer. The TECCELL used in this project is made of recycled PP resin from collected bottles.

As the core company of the NX Group, Nippon Express provides high-quality, sustainable logistics services globally, utilizing air, ocean, rail, truck, warehousing, and IT. It is also the “recommended logistics provider” and “designated on-site cargo handling provider” for the Osaka/Kansai Expo.

Manufactures and sells plastic industrial materials, industrial parts, and medical parts, as well as daily commodities and water pipe fittings. TECCELL, a next-generation honeycomb core material with extremely high specific strength and specific rigidity, is being commercialized.
