Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The prices of polyolefins are expected to remain under pressure. There are no new production plans in November, but some maintenance devices will restart, increasing the capacity expansion pressure and intensifying the imbalance between supply and demand. The downstream demand is weak, with the seasonal peak of agricultural film production passing, the demand for pipes increasing first and then decreasing, and the downstream's willingness to stock up being low due to fear of price drops [6] 3. Summary by Directory 3.1 Market Review and Outlook - **Futures Market Performance**: The L2601 contract of linear low - density polyethylene (LLDPE) opened higher, fluctuated during the session, and closed down at 6,788 yuan/ton, a decrease of 6 yuan/ton (-0.09%), with a trading volume of 186,000 lots and an increase in positions by 2,586 lots to 586,919 lots.

The downstream demand is weak. The agricultural film production has reached a seasonal peak and is declining, the demand for pipes increases first and then decreases, the plastic weaving of PP is boosted by packaging demand, and BOPP enterprises mainly digest inventory. The downstream's low willingness to stock up due to fear of price drops further drags down the transaction price [6] 3.2 Industry News - **Inventory**: On November 12, 2025, the inventory level of major producers was 690,000 tons, a decrease of 20,000 tons (-2.82%) from the previous working day, compared with 680,000 tons in the same period last year [7] - **PE Market Price**: The prices of LLDPE in some areas decreased.

Report Information - Report Title: Polyolefin Daily Report [1] - Date: September 24, 2025 [2] - Research Team: Energy and Chemical Research Team [4] Investment Rating - Not provided Core View - Futures continued to be weak, dampening market sentiment. Traders reduced prices to promote sales, leading to a decline in spot prices. Downstream buyers mainly purchased on - demand. The market was in a state of low - level weak oscillation due to limited demand drive and insufficient market confidence [6]. Summary by Directory 1. Market Review and Outlook - **Futures Market**: L2601 opened lower, fluctuated during the session, and closed down at 7105 yuan/ton, down 48 yuan/ton (-0.67%), with a trading volume of 180,000 lots and an increase in positions by 8837 lots to 589,676 lots. PP2601 closed at 6842 yuan/ton, down 53 yuan (-0.77%), with an increase in positions by 7134 lots to 654,200 lots [5][6]. - **Supply - side**: For polypropylene, the upstream maintenance level exceeded expectations, with more shutdown devices, resulting in a decline in capacity utilization and output. Due to the recent strengthening of propane prices, the profit of PDH plants continued to be compressed, and the operating load rate declined, alleviating supply - side pressure. Some maintenance plants will restart this week, and output may increase month - on - month. For PE, the maintenance volume declined from the high level, and the supply pressure increased month - on - month [6]. - **Demand - side**: Except for the increase in the operating rate of agricultural film, most other fields remained flat. The peak - season performance was lower than expected, and the downstream operating rate and orders were at a relatively low level year - on - year. Factories were cautious in raw material procurement, showing a situation of "peak season without prosperity", which had limited support for the raw material market. The destocking rhythm of social inventory in the middle stream was slow, and it was difficult to push up prices [6]. - **Macro - aspect**: The expectation of interest rate cuts was implemented, but the chemical sector showed a flat performance. There was still some support from the increasing demand for packaging products near the double festivals, but due to insufficient market confidence, there was no large - scale replenishment behavior, and the demand drive was limited [6]. 2. Industry News - **Inventory**: On September 23, 2025, the inventory level of major producers was 680,000 tons, a cumulative increase of 50,000 tons from the previous working day, an increase of 7.94%. The inventory in the same period last year was 810,000 tons [7]. - **PE Market**: The PE market price weakened and declined. The LLDPE price in North China was 7060 - 7400 yuan/ton, in East China was 7150 - 7650 yuan/ton, and in South China was 7250 - 7700 yuan/ton [7]. - **Propylene Market**: The mainstream price of propylene in the Shandong market was temporarily referred to as 6450 - 6520 yuan/ton, a decrease of 50 yuan/ton from the previous working day. The market supply trend increased, and producers still had the intention to sell at a discounted price. The propylene quotations mostly declined slightly, and downstream factories purchased at low prices. The low - end transactions in the market were acceptable [7]. - **PP Market**: The PP market continued to decline, with a decline range of 10 - 70 yuan/ton. The new orders of downstream factories were limited, and the pre - festival procurement enthusiasm was insufficient. The mainstream price of North China drawstring was 6690 - 6780 yuan/ton, in East China was 6700 - 6840 yuan/ton, and in South China was 6650 - 6830 yuan/ton [8]. 3. Data Overview - The report provides various data charts, including L - PP spread, crude oil futures settlement price, two - oil inventory, two - oil inventory year - on - year increase or decrease rate, L basis, and PP basis, with data sources from Wind and Zhuochuang Information [11][13][14]

1. Report Industry Investment Rating - No information provided 2. Core View of the Report - The overall supply of domestic cis - butadiene rubber is sufficient. Under the influence of downstream bargain - hunting purchases, the negotiation focus on the spot side is continuously under pressure. Some industry players expect a certain reduction in the mainstream supply price. This week, both enterprise inventories and sample trading enterprise inventories have decreased slightly. Before the holiday, downstream enterprises have pre - holiday stocking needs, and it is expected that buyers will gradually follow up, and the inventory level is expected to continue to decline. In terms of demand, the capacity utilization rate of domestic tire enterprises has increased slightly this week. Most enterprises maintain their current production schedules to reserve inventory around the long holiday and make up for the previous order gap. The overall capacity utilization rate will mainly fluctuate slightly. The short - term price of the BR2511 contract is expected to fluctuate in the range of 11,250 - 11,700 [2] 3.

Report Summary 1. Report Industry Investment Rating - No information provided in the report. 2. Core View of the Report - The production of domestic cis - butadiene rubber has increased due to the restart of previously - shut - down devices, and the supply is expected to rise significantly. The inventory level of finished products is likely to increase. In terms of demand, the capacity utilization rate of domestic tires fluctuated slightly last week. Some semi - steel tire enterprises' maintenance plans dragged down the overall capacity utilization rate, while the resumption of work of all - steel tire maintenance sample enterprises drove up the capacity utilization rate. Although there is still room for a slight increase in capacity utilization rate, the general order performance and enterprise production control will limit the increase. The br2510 contract is expected to fluctuate in the range of 11,600 - 12,000 yuan/ton in the short term [2]. 3.
