As an upgraded alternative to PTFE, the "king of plastics", ETFE (Ethylene-Tetrafluoroethylene Copolymer) has become an "invisible champion" in high-end manufacturing with its outstanding performance. Developed jointly by DuPont and NASA, this material breaks through the processing difficulties of traditional fluoroplastics through molecular structure modification, while retaining advantages such as corrosion resistance and high temperature resistance (-200℃ to 220℃).
    Today, ETFE has formed a global multi-polar competitive pattern. Japan's AGC holds over 50% of the market share, while Chinese enterprises like Dongyue Group and Juhua Co., Ltd. are catching up rapidly, with the domestic market scale reaching 672 million yuan in 2025. Its applications span construction, electronics, new energy and other fields, including the 95% light transmittance membrane structure of Beijing's "Water Cube", semiconductor anti-corrosion materials, and solar module packaging, accounting for over 62.5% of applications in the electronic and electrical field.
    With green low-carbon and functionalization as the trends, degradable ETFE and recycling technologies are gradually being implemented. Driven by the growing demand in the new energy sector, the global market scale is expected to reach 3.466 billion yuan by 2032. The technological breakthroughs of Chinese enterprises are reshaping the global market pattern, bringing this high-end material into more civilian scenarios.
