With the development of science and technology and electronic technology, especially under the concept of Industry 4.0, the intelligentization of equipment and the Internet of Everything have used a large number of electronic products on the equipment. The reliability requirements of these products are very high, and the heat dissipation requirements and EMI requirements are also very urgent.

        National defense and military products, but also the demand for high-precision parts. The requirements for thermal conductivity and EMI are even more demanding. Such as phased array radar, missiles, military command vehicles, stealth fighters, stealth drones, etc., a variety of high-specification thermal interface materials, conductive shielding materials and electromagnetic absorbing materials are required.
