Electronic-grade fiberglass cloth, a key input for copper-clad laminates and printed circuit boards used in data-center servers, smartphones and 5G base stations, has seen five rounds of price increases so far this year; the market-average price is 7.4 yuan/m, about 100% above last year’s Q3 low. A surge in compute demand is driving the rise. High technical requirements for equipment and process control are constraining capacity expansion; producers and industry sources warn electronic-yarn expansion cycles are long and high-end capacity will take time to come online, so supply tightness may persist and the timing of a supply-demand rebalancing is uncertain.
