China's PP sector is moving through its heaviest maintenance window of 2026, as overlapping shutdowns at major facilities point to tighter domestic availability heading into year-end, according to CommoPlast's Nov. 4 briefing.
Production losses are set to peak in November before easing into December, placing the heaviest strain on supply in the near term. The concentrated outages could lend some supply-side support at a time when feedstock costs are climbing.
Soft downstream demand and buyers' resistance to higher resin prices continue to cap producers' pricing leverage. Tighter prompt availability may spur pre-Lunar New Year restocking.
The return of idled capacity toward year-end could loosen supply conditions again, leaving the price outlook dependent on whether buying interest picks up. Naphtha and ethylene costs were indicated as firm or rising in the region.
