Capacity utilization was 80.47%, a decrease of 1.02 percentage points from the previous period, and production was 2.7079 million tons, a decrease of 4.22 percentage points from the previous period.

Market Outlook - For PE in October 2025, domestic supply will face pressure from the return of maintenance and the commissioning of new devices. Import volume will increase under the condition of loose overseas supply. Demand growth is slower than in previous years, resulting in a situation of oversupply in the fourth quarter. There is an expectation of inventory accumulation after the National Day holiday, so PE prices may decline after the holiday [8] - For PP in October 2025, the planned maintenance loss is expected to increase by 0.2%. The 400,000 - ton/year PP plant of PetroChina Guangxi Petrochemical is expected to be put into operation, and production is expected to increase by 3.54% month - on - month to 3.463 million tons.
