China’s polypropylene market is watching developments at Hengli Petrochemical after the company initiated a planned shutdown of its No. 2 polypropylene (PP) unit on Changxing Island. According to industry sources, the facility was taken offline on September 12, 2025 for maintenance, though the company has not confirmed how long the outage will last.
The No. 2 unit, with a production capacity of 200,000 metric tons per year, is a key contributor to regional PP supply. Polypropylene is widely used in packaging, automotive parts, textiles, and consumer goods, and even a temporary pause at a plant of this scale can influence market sentiment and pricing dynamics across Asia.
Market participants are closely monitoring the situation as they await an official update. Until the company provides a definitive restart schedule, traders and downstream manufacturers remain cautious, weighing the potential impact on supply availability and contract negotiations in the weeks ahead.
