Graphite sheet has about 4 times the thermal conductivity of copper and about 7 times that of aluminum!
For graphite processing, please consult with Showa, which has a proven track record!
"Graphite sheets" are lightweight materials with very high thermal conductivity in the plane direction. Our company provides products tailored to customer needs based on our extensive processing experience. We can also offer suggestions for powder/layer delamination measures. 【Applications】 ■ Thermal Conductive Materials Used as thermal conductive materials for efficiently conducting heat, such as cooling materials for electronic devices and semiconductor devices. ■ Vibration Damping Materials Used as vibration damping materials for machines and engines due to their ability to absorb vibrations. ■ Electrode Materials Excellent electrical conductivity makes them suitable for use as electrode materials in electrochemical devices such as batteries and fuel cells. ■ Heat Resistant Materials Graphite sheets have properties that withstand high temperatures, making them suitable for applications in high-temperature environments, such as insulation materials for high-temperature kilns and furnaces.

Company information
Showa Corporation is a company that develops various businesses, including resin washers, heat dissipation component processing, and special molding processing. In particular, regarding resin washers, which have been processed since the company's founding, we have approximately 800 molds in-house. If we have the desired size or a similar size in our molds, there is no mold cost. We can handle processing from prototypes of a single product to mass production of hundreds of thousands of units. We also have machines such as plotters and super cutters that can process without initial costs, and we can propose processing methods and materials according to customer requests. As part of our BCP response and technology development, we have newly established Showa R&D Center Co., Ltd. in Okayama Prefecture. We will continue to leverage the experience and know-how we have cultivated to challenge new processing and fields.
