How is domestic substitution reshaping Advanced Materials capacity and pricing in China?
Localization is advancing at different speeds across Advanced Materials. Modified PPO production is established, yet domestic self-sufficiency stays near 30 percent, leaving room to grow. Ultra-high molecular weight polyethylene capacity jumped sharply as integrated refining projects started up, but output lagged and utilization fell, showing that new plants need time for process tuning and customer qualification. In alpha-olefins, breakthroughs in ethylene oligomerization and POE units are reducing import dependence, and integrated refining bases give Chinese producers a cost edge over overseas rivals once logistics are counted.
