China activated the world's largest electronic-grade fiberglass production line on March 18, 2026, at its zero-carbon manufacturing base in Huai'an, Jiangsu Province. This breakthrough strengthens China's position in advanced materials manufacturing while aligning with global decarbonization goals.
Electronic-grade fiberglass serves as the foundational material for printed circuit boards (PCBs) – essential components in everything from smartphones to AI servers. The new facility boasts an annual output of 390 million meters, capturing 9% of global supply capacity. Project leader Gu Jianding emphasized the plant's environmental credentials: "The facility currently operates on 100% green electricity," powered by an on-site 233-megawatt wind farm generating over 600 million kWh annually.
The production line integrates domestically developed technologies including high-performance glass formulations and ultra-large energy-efficient furnaces. Output will primarily support China's booming new energy vehicle sector, photovoltaic installations, and emerging low-altitude economy applications.
Industry analysts note this development reduces import reliance for high-end electronic base materials critical to next-generation technologies like AI servers and high-frequency communication systems. The project's combination of scale and sustainability sets new benchmarks for advanced manufacturing infrastructure worldwide.
