Electromagnetic shielding film is a functional material that mitigates electromagnetic interference and provides radiation protection by suppressing electromagnetic wave propagation. Its core functions include attenuating electromagnetic wave transmission, preventing information leakage, and ensuring stable performance in complex operating environments. Based on material composition, these films are categorized into metal-based, carbon-based, ceramic-based, and polymer-based types.
Currently, applications of electromagnetic shielding films are rapidly expanding from traditional consumer electronics into automotive electronics, communication data centers, and the semiconductor industry. Future growth will be driven by the expansion of computing infrastructure, advances in semiconductor packaging, and accelerated automotive electrification, all of which necessitate ongoing innovation in high-efficiency shielding technologies. Overall, the rapid development of data centers and artificial intelligence (AI) is a key catalyst for the growth of China's electromagnetic shielding film market.
The overall market size of composite materials for communication cables in China steadily increased from 7.2 billion yuan in 2020 to 11.97 billion yuan in 2024, and is projected to reach 29.19 billion yuan by 2029. Driven by the demand for computing centers, the market for composite materials for communication cables rapidly expanded from 210 million yuan in 2020 to 610 million yuan in 2024, and is expected to surpass 4.43 billion yuan by 2029, becoming the core growth driver of the industry.
