A tape-making giant with annual revenue exceeding 5 billion yuan is pivoting into the high-barrier field of electronic-grade fiberglass fabric. Yongguan New Material recently signed an agreement with the Dongxiang District government in Jiangxi to invest 300 million yuan in a project with an annual capacity of 2,000 tons of electronic-grade fiberglass fabric. This move is not merely capacity expansion but a strategic leap from traditional tape substrates to high-performance electronic materials.
Background
Electronic-grade fiberglass fabric is a core reinforcement material for printed circuit boards (PCBs), directly determining signal transmission speed and insulation performance. Demand for high-frequency, high-speed PCBs—driven by 5G base stations, data center switches, and automotive electronics—is surging, boosting the upstream electronic-grade fiberglass fabric market in both volume and price. Yongguan's timing aims to capture this structural growth window.
The Dongxiang district government has pledged comprehensive support in land, labor, and energy. For local authorities, a 300-million-yuan new materials project not only creates jobs but can also attract upstream and downstream supporting industries, forming a cluster anchored by Yongguan. Dongxiang already hosts Yongguan's tape production base; this expansion into electronic-grade fiberglass fabric is essentially a vertical extension within the same industrial park.
Industry Impact
Yongguan's cross-sector advantage lies in process synergy. Over 20 years of producing fiberglass tape and cloth-based tape, the company has accumulated core technologies in precision weaving, sizing, tension control, and surface treatment. These processes overlap heavily with electronic-grade fiberglass fabric production—from warping and sizing of fiberglass yarn to weaving and post-treatment, where the key challenges are tension uniformity and surface cleanliness. In other words, Yongguan is not starting from scratch but migrating existing know-how to a higher-value product line.
An annual capacity of 2,000 tons is moderate for mid-sized projects, but for the niche electronic-grade fiberglass fabric segment, it offers significant scale benefits. Industry data shows China's electronic-grade fiberglass fabric market was worth approximately 8 billion yuan in 2025, growing at 8%-12% annually. At full capacity, Yongguan could capture about 2.5% market share, intensifying competition with established players like Honghe Technology and Guangyuan New Material.
For downstream PCB makers, this means a new supplier with cost advantages and stable supply capability enters the field. Yongguan's supply chain management experience from the tape business gives it natural advantages in raw material procurement and logistics. Additionally, the Dongxiang base, located in central China, benefits from lower labor and energy costs than coastal regions, potentially offering more competitive pricing post-production.
