A tape giant with annual revenue exceeding 5 billion yuan is now venturing into electronic grade fiberglass fabric. Yongguan New Materials 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. While this volume is modest compared to the global market—which already exceeds one million tons annually—the real significance lies in the company's strategic shift from adhesive tapes to high-performance electronic substrates.
Technology Migration: Shared Weaving Expertise
Yongguan has accumulated over two decades of precision weaving experience in fiberglass tape and cloth-based tape, including sizing, tension control, and surface treatment. The core challenge of electronic grade fiberglass fabric lies precisely in yarn tension consistency, uniformity of surface treatment, and precise sizing formula control. In other words, this is not a leap into an entirely new field but an upward extension within the same material system.
Electronic grade fiberglass fabric typically ranges from 18 to 100 microns in thickness, demanding much higher standards for yarn elongation, fabric flatness, and hairiness control than ordinary industrial fabrics. Yongguan's existing tension control systems and surface treatment processes can be partially transferred to electronic fabric production lines, significantly lowering technical barriers and trial costs.
Industrial Cluster Advantage: Dongxiang's Location and Policy Support
Yongguan's choice of Dongxiang is no coincidence. The company has operated there for 14 years, with multiple production bases and deep familiarity with the local industrial ecosystem and policy environment. Dongxiang is located in eastern Jiangxi, adjacent to the Yangtze River Delta electronics information cluster, within two hours' drive of Nanchang High-Tech Zone and Shangrao Optoelectronics Park, facilitating supply chain coordination with downstream copper-clad laminate (CCL) and printed circuit board (PCB) manufacturers.
From the local government's perspective, Dongxiang is promoting a strategy of "leading enterprise guidance, chain integration, and cluster synergy," with electronic grade fiberglass fabric fitting squarely into the new materials core track. The district government has pledged comprehensive support in land, labor, and energy, providing a significant risk mitigation factor for a project with a long investment cycle and slow return.
Downstream Demand: Dual Drivers of Automotive Electronics and 5G
Electronic grade fiberglass fabric is primarily used in CCL, which is the core substrate for PCBs. The global electronics industry is undergoing structural upgrades: the electrification rate of automobiles continues to rise, with a new energy vehicle requiring 3-5 times more PCB than a traditional fuel vehicle; 5G/6G base station construction and data center switch upgrades are also driving demand for high-frequency, high-speed CCL.
Yongguan's entry targets this structural increment. An annual capacity of 2,000 tons may be small, but it focuses on high-end differentiated products—such as low dielectric constant, low-loss electronic fabrics—which typically have gross margins above 30%, far exceeding the 15% level of ordinary industrial fabrics.
Competitive Landscape and Risks
The domestic electronic grade fiberglass fabric market is dominated by leaders such as Taishan Fiberglass and Chongqing Polycomp International, with the top five players holding over 60% market share. New entrants face not only a long technology validation cycle (typically 12-18 months for downstream certification) but also yield control challenges during capacity ramp-up. Yongguan's advantage lies in the stable cash flow from its tape business—over 5 billion yuan in revenue in 2024—providing a sufficient safety net for early-stage losses in the electronic fabric project.
A potential risk is overcapacity. Since 2023, new capacity in the domestic electronic fabric industry has been released intensively, with some categories seeing price declines of 10%-15%. If Yongguan fails to achieve rapid breakthroughs in differentiated products, it may fall into a price war trap.
