China Jushi Launches World's Largest Electronic-Grade Glass Fiber Plant

Select Language:

China’s largest electronic-grade glass fiber manufacturing facility has begun operations in Jiangsu Province’s Huai’an city. The new plant is now producing, with an annual capacity of 100,000 tons of electronic-grade glass fibers and 390 million meters of electronic cloth, according to the company’s announcement.

Electronic-grade glass fibers serve as vital raw materials for printed circuit boards. Their quality directly influences the dielectric properties, thermal expansion, and durability of these boards. As such, they are considered fundamental components in supporting the digital economy.

The facility specializes in manufacturing advanced electronic base materials, including ultra-fine yarns and ultra-thin fabrics. Once operating at full capacity, it is expected to efficiently supply the growing demand from emerging sectors like high-end servers and automotive electronics that require high-performance PCBs.

This project is projected to play a significant role in ensuring a stable supply chain within the electronics industry, said the company’s general manager. The plant will supply premium raw materials to sectors such as consumer electronics, 5G communications, and industrial control systems, thereby supporting China’s efforts to build its new information infrastructure.

Thanks to the adoption of cutting-edge digital technologies, such as industrial internet, AI-powered quality inspections, and digital twin systems, the Huai’an plant has achieved end-to-end automated production. It is also recognized as the world’s first green, zero-carbon smart manufacturing base for glass fibers, powered by a self-operated wind farm.

The company currently controls 23 percent of the global electronic glass fiber market share and projects this will increase to 28 percent with full operation of the Huai’an plant.
