Capacity utilisation
not published
Chinese UPR plants are many and small; output rose in 2023-2024 on downstream demand and higher run rates (Chyxx).

Concentration
China about half of world output; Asia-Pacific 43.45% of 2025 revenue
The industry is fragmented: many Chinese producers and a few Western groups (INEOS Composites, Polynt, AOC, Scott Bader). Top-5 company share not published.

New capacity
not published
No large named UPR projects found. Growth comes from incremental batch reactors, mostly in China and India (indicative).
