HighChem Co., Ltd. (Headquarters: Minato-ku, Tokyo; President & CEO: Taka Ushio; hereinafter "HighChem"), a global chemical trading company and manufacturer, has developed and commercialized a "Highly Thermally Conductive Sheet" with thermal conductivity exceeding 15W/m･K.​​​​​ This development was achieved in collaboration with a Japanese materials development company (hereinafter "partner company"). Additionally, ​​the company will offer customized products combining thick copper substrates for high current applications such as IGBT (Insulated Gate Bipolar Transistor) with the highly thermally conductive sheets.​

Power devices used in home appliances such as air conditioners and refrigerators, electric vehicles (EV), high-output LED, trains, and solar power generation systems are generating increasing amounts of heat as they become smaller, lighter, and more energy-efficient, making thermal management materials increasingly important. In particular, thermally conductive sheets play a crucial role in efficiently dissipating heat by filling and adhering the space between heat-generating IC (Integrated Circuit) chips and heat sinks. These materials require high thermal conductivity, adhesion, and flexibility, making the development of higher-performance products urgent.​​​​​​

Conventional thermal management materials are typically ceramic-based, requiring sheet thicknesses of 0.3 millimeters to 1.0 millimeters, which limits design flexibility and poses cost challenges. The "Highly Thermally Conductive Sheet" jointly developed by HighChem and its partner company uses special resins to achieve sheet thicknesses of 0.05 to 0.1 millimeters, significantly thinner than conventional ceramic products, enabling lighter weight, higher design flexibility, and lower costs. Furthermore, through proprietary manufacturing technology from HighChem and its partner company, the sheet incorporates ceramic powder into the resin matrix to ​​​​​​​​achieve thermal conductivity exceeding 15W/m･K while maintaining strong adhesion and insulation properties.​​​​​​

Moreover, the company can provide customized manufacturing of combinations featuring thick copper substrates for high current applications such as IGBT with highly thermally conductive sheets, enabling thermal management solutions tailored to customer needs.​​

HighChem, a company with both chemical trading and manufacturing capabilities, has various products and technologies ranging from life science fields such as pharmaceuticals, food, and agrochemicals, to cutting-edge electronic materials. The Sustainability & Innovation Division, which represents its manufacturing function, has four research centers and one catalyst factory in Japan and China, and developing and commercializing decarbonization technologies which use CO2 as feedstock to produce chemicals. Meanwhile, HighChem C1-based SEG®, has already achieved a big success with a total capacity of more than10 million tons per year. HighChem also committed to develop biochemical technologies and next-generation battery technologies and  globalize its business, offering more innovative products, technologies, and services.4 The company has two research laboratories and a catalyst mass production factory, with an annual production capacity of 1,000 We boast a track record of licensing 10,000 tons C1 system SEG ^® Based on technology, CO2 We are also focusing on the development of biochemical technologies and storage battery systems, as well as the development and commercialization of decarbonization technologies that utilize renewable energy to manufacture Chemicals. We will continue to expand our business globally, centering on more innovative products, technologies and services.
