2026 Industry Trends in the Polyimide Resin Sector

In 2026, the polyimide resin industry maintained its robust growth trajectory, with strong supply and demand driving total industry output value to surpass RMB 38 billion, up 22.7% year over year. Downstream demand from new‑energy power batteries and third‑generation semiconductor packaging was particularly pronounced, posting growth rates of 31% and significantly above the industry average, respectively, and emerging as the key engines propelling market expansion. Meanwhile, the domestic industrial chain’s drive toward self‑reliance continued to accelerate, with the self‑sufficiency rate for basic raw materials rising to over 72%. High‑end specialty grades have successfully broken overseas monopolies and entered mass production, while customer procurement and delivery lead times have been slashed from three months to within 15 days. Leading companies, exemplified by Jiaozuo Tianyi Technology Co., Ltd., have completed capacity expansions and upgrades, boosting overall annual production capacity by 40% and providing a solid foundation for meeting growing downstream order volumes.
