The fiberglass price uptrend has officially emerged in 2026. This is not a short-term fluctuation, but a long-term upward cycle driven by reshaped industry supply and demand fundamentals, with continued price growth expected. The overall industry environment is tightening, and rising raw material costs will become a sustained trend for downstream manufacturers.
The price increase is backed by solid long-term structural factors. Booming demand for AI, PCBs and advanced chip packaging has led to a severe shortage of high-end micro-fiberglass materials. With the industry maintaining a steady annual growth rate of 5%–6%, the supply-demand gap will persist in the long term.
The global fiberglass supply chain continues to tighten. Leading manufacturers, including Japan’s Nittobo, have raised prices of high-performance specialty yarns such as T-glass for AI hardware by more than 20%–30%. Meanwhile, major domestic producers, including Jushi and Taishan Fiberglass, will conduct furnace cold repairs in 2026, resulting in overall capacity reduction. Rising energy costs further reinforce the long-term upward trend of fiberglass prices.
Slight price declines in raw materials such as soda ash have only moderately eased the price increase of standard E-glass and prevented extreme price surges, but cannot reverse the overall industry trend of rising prices and tight supply.
In summary, tight supply and rising prices have become a confirmed long-term norm for the 2026 fiberglass industry. It is recommended that downstream customers optimize procurement budgets and lock material costs in advance to cope with continuous cost inflation.
