未知机构：玻璃布供应持续吃紧业者计划启动第二轮涨价-20260224

Summary of Conference Call Records Industry Overview - The glass fabric supply is experiencing a continuous tightening, leading to plans for a second round of price increases. Suppliers and industry insiders predict that due to rising costs and supply constraints, monthly price adjustments are expected. If this trend continues, prices could potentially double by the end of 2026, impacting the electronics and PCB industry chain significantly [1][1][1]. Key Points and Arguments - Price Increase Dynamics: Since October 2025, there have been four rounds of price increases for ordinary electronic fabric, with the adjustment cycle shifting from quarterly to monthly. This new round of price hikes is not starting from a low base, as the cumulative annual increase in glass fiber has already exceeded significant levels [1][1][1]. - Reasons for Price Increases: - Increased PCB layer counts for AI servers leading to a sharp rise in the amount of electronic fabric used, resulting in supply shortages [2][2][2]. - High demand for low dielectric constant (low-Dk) and low thermal expansion coefficient (low-CTE) electronic fabrics, which are also in short supply [2][2][2]. - Dependence on imported core equipment, complex drawing processes, and lengthy customer certification cycles (2-3 years) contribute to supply constraints [2][2][2]. - Cost Factors: Rising costs of resin and energy, combined with increased transportation and environmental compliance costs, are further driving price increases [3][3][3]. - Market Analysis: Huatai Securities reports that the new round of price increases is substantial and the cycle is shortening, indicating a spread of the tight supply situation from high-end to ordinary products. The supply of ordinary electronic fabric is significantly constrained, with expectations for a new price increase cycle starting in 2026. High-end electronic fabrics, particularly second-generation low dielectric and low thermal expansion products, will still face supply gaps in 2026, likely leading to further price increases [4][4][4]. Additional Important Insights - Electronic-grade glass fiber fabric (electronic fabric) is a crucial raw material for manufacturing core copper foil substrates for electronic products. Since the second half of 2025, high-end electronic fabric has been in short supply, with prices continuously rising [4][4][4]. - Citigroup analysts predict that the price increase for electronic fabric could reach significant levels in 2026, potentially affecting end products such as smartphones and laptops [4][4][4]. - Several companies in mainland China have recently made progress in the high-end electronic fabric sector. For instance, International Composites has developed low dielectric glass fiber for 5G applications, which has been certified by customers and is now in mass production. Zhongcai Technology's products include low dielectric first and second-generation fiber fabrics, all of which have completed domestic and international customer certifications and are in mass supply [4][4][4]. - Glass fabric accounts for approximately 30% of the cost of copper foil substrates, and the price increase has already led to rising costs in copper foil substrates, which are being transmitted through the PCB industry chain [5][5][5]. - Nitto Denko, a major supplier of T-shaped glass fabric, holds over 90% of the global supply of low thermal expansion electronic fabric, but new production capacity is not expected to come online until 2027, which will enhance performance by approximately 20% [5][5][5]. - Some manufacturers are shifting production capacity from traditional E-glass to the more in-demand low dielectric glass fabric, exacerbating the supply gap for ordinary electronic fabric [5][5][5].
