Recently, the ‘electronic fabric’ concept has gained strong momentum in China’s A-share market, driving significant gains in related stocks. Notably, International Fiberglass & Composites Co., Ltd. (Chongqing-based) saw its share price surge by over 10% in a single day, drawing widespread market attention. Electronic fabric—also known as electronic-grade glass fiber cloth—is a critical raw material used in the production of copper-clad laminates (CCL) and printed circuit boards (PCB). It is widely applied in 5G communications, consumer electronics, automotive electronics, and semiconductor packaging. With the acceleration of global digitalization, especially surging demand for high-end PCBs from emerging technologies like AI, high-performance computing, and electric vehicles, electronic fabric’s strategic importance as an upstream component has become increasingly evident.As a leading Chinese manufacturer of fiberglass and composite materials, International Fiberglass possesses strong technical expertise and production capacity in the electronic fabric segment. The company has consistently increased R&D investment in high-end electronic yarns and fabrics in recent years, with its products already integrated into the supply chains of several top-tier CCL manufacturers. Recently, improved downstream demand, stabilized raw material costs, and a more favorable industry supply-demand balance have led to a recovery in electronic fabric prices, boosting market expectations for profitability among related firms. Analysts suggest that if the current upcycle in electronic fabric continues, industry leaders like International Fiberglass could achieve dual growth in both earnings and valuation.
