Toray Industries, Inc. (President: Akihiro Nikkaku) has announced that it has developed a polyimide material suitable for electronic components used in 5G1 communications and for millimeter-wave radar. 5G is an increasingly popular high-speed, stable communications technology capable of handling large data volumes, and millimeter-wave radar is employed in automated driving and other technologies.
The new Toray material has the heat resistance, mechanical characteristics and adhesive properties typical of polyimides, coupled with the low-dielectric-loss performance that is essential for high-speed communications. It is expected to make a significant contribution to the performance of high-frequency parts in electronic components in these fields.
The new material leverages Toray’s many years of experience in functional polyimide design technologies and precision molecular design driven by an R&D approach of pursuing the ultimate limits. The low-dielectric-loss polyimide material features high heat resistance and superior mechanical and adhesive properties, and it reduces electrical energy loss ratio (loss tangent) to 0.001 (20GHz).
Toray will continue to pursue the potential of the new material with further development efforts, including adding photosensitivity properties and manufacturing the material in B-stage sheet form.
The application of the new material will reduce electrical energy loss and also enable the stable high-speed transmission of large data volumes, boost the performance of millimeter-wave radar for distance measurement, and contribute to the miniaturization of components.
Toray continues to work to commercialize various resins optimized for the 5G era. The addition of this newly developed material to its product lineup is a strong step forward in Toray’s efforts to provide advanced materials for semiconductor devices and electronic components that will support the next generation of communications technologies.
The Toray Group continues to leverage its core technologies in organic synthetic chemistry, polymer chemistry, biotechnology, and nanotechnology to research and develop innovative materials and technologies that have the potential to transform society at a fundamental level. This is how the Toray Group delivers on its corporate philosophy of “contributing to society through the creation of new value with innovative ideas, technologies and products.”
