Official launch of the SPACECOOL® magnetic sheet, a new material that utilizes radiative cooling technology.
SPACECOOL INC. (CEO: Takayuki Hoshuyama) has officially launched the SPACECOOL® magnetic sheet, which utilizes the radiative cooling material SPACECOOL® (hereinafter the “Material”).
The Material is a radiative cooling*¹ material designed to lower temperatures below the outside temperature*² when placed under direct sunlight without using energy by releasing heat back into space. In a demonstration experiment conducted by Osaka Gas, the company that developed the Material, it was shown that the surface temperature of the Material was, at maximum, approximately 6°C*³ lower than the outside temperature when placed under direct sunlight. This makes its radiative cooling performance*⁴ the best in the world, creating potential for it to be adopted as part of efforts to counter global warming, promote energy-saving, and as a comfortable cooling material.
Three types of products that utilize the Material have already been launched: film, tarpaulin, and canvas. The launch of this new magnetic sheet allows the product to be more easily installed on and removed from steel outdoor equipment, outer walls, and roofs.
Our Company will continue to develop new products based on the Material that are even easier for our clients to use.
*1: A phenomenon where heat from an object that has been heated up is carried off as electromagnetic waves (light).
*2: Achieved through the use of a proprietary optical control technology to create a material design that suppresses heat input from sunlight and amplifies heat dissipation through thermal radiation.
*3 Measured at the Osaka Gas Co., Ltd. Energy Technology Laboratories in Konohana-ku, Osaka, at an ambient temperature of around 35°C.
*4 Based on research conducted by Osaka Gas and SPACECOOL using publications that are publicly available.
About the product
The product officially launched is a magnetic sheet with the following appearance and features (Figure 1, Table 1).


Applications
The magnetic sheet can be installed on steel outdoor equipment more easily than its film counterpart, and it can also be easily removed and reinstalled depending on the time of year and location.
