High heat dissipation characteristics are achieved by combining “the thermal conductivity of copper” and “the breathability of paper”
TOMOEGAWA's Copper Fiber Sheet is a 100% copper sheet. Sheets produced using papermaking technology combine “the electrical conductivity and thermal conductivity of copper” and “the porous and cushioning properties of paper”. [Features] 1. High heat dissipation properties The specific surface area is approximately 10 times geater than that of copper foil, resulting in high heat dissipation due to its porous structure. 2. Flexibility like paper It is highly flexible and can absorb thermal dimensional changes caused by differences in the coefficient of linear expansion. 3. Lightwight and thin Approximately 1/3 the weight of bulk copper foil of the same volume due to its porous structure. Also, it can be used in thickness of 100 μm or less, contributing to product weight reduction and space savings. 4. Customizable of various characteristics. Customization according to the required properties is possible by controlling fiber diameter and thickness. [Application] - Heat dissipation modules - Electrode related materials

Company information
In June 1914, TOMOEGAWA started its path as a pioneer of industrial specialty paper in Japan, and succeeded in domestic production of “electrical insulating paper and telecommunications paper” to meet the needs of telecommunications industry. In the 1960s, we earned a reputation as a 'Tomoegawa of Specialty' by developing papers for multiple industries, with our strength in integrated production from wood pulp. Since then, TOMOEGAWA has developed "papermaking, coating, adhesive, powder" technologies and expanded its business domains to "highly functional materials." In recent years, with the spread of 5G, advanced driver assistance systems, etc., and the promotion of DX, many electronic parts require control for high voltage, high current, high frequency. TOMOEGAWA has expanded our "iCas" brand products that control "heat, electricity, and electromagnetic waves" to produce various solutions for heat, noise, etc. TOMOEGAWA has also formed “GREEN CHIP” brand, focusing on new products that contribute to the conservation of the natural environment and control of manufacturing and operating environments. In addition, we have changed our company name from TOMOEGAWA Co., Ltd., to TOMOEGAWA CORPORATION on January 1, 2024, in order to clarify the actual situation of our company and aim for sustainable corporate growth.
