1. Today's Summary

In October, OPEC+ plans to increase production at a relatively moderate pace, and the risk of U.S. sanctions on some oil-producing countries still exists, leading to a rise in international oil prices. NYMEX crude oil futures for the October contract rose by $0.39 to $62.26 per barrel, a month-on-month increase of 0.63%; ICE Brent crude futures for the November contract rose by $0.52 to $66.02 per barrel, a month-on-month increase of 0.79%.

②. The price fluctuation range for the HDPE market is -4 to 3 yuan/ton, the LDPE market price is -2 yuan/ton, and the LLDPE market price is -1 yuan/ton.

2. Overview of Spot Market

Table 1   Domestic Polyethylene Closing Price Summary (Unit: RMB/ton)

Raw material support still exists, production plant maintenance has increased, resulting in reduced output. However, peak season orders from downstream have not materialized, leading to weakened market confidence. Today, transactions are maintained on a just-needed basis. The HDPE market price fluctuated by -4 to 3 yuan/ton, LDPE market price by -2 yuan/ton, and LLDPE market price by -1 yuan/ton.

3. Price Prediction

In the short term, On the supply side, inventory pressure has eased. On the demand side, downstream is gradually entering the traditional peak season, but downstream enterprises still have a certain level of inventory, and the increase in orders is not significant, maintaining mainly just-in-time demand. Therefore, the polyethylene market is expected to fluctuate within a narrow range tomorrow. 。

PP: Demand Slowly Recovers, Polypropylene Market Consolidates Within a Range

1. Today's Summary

① China National Petroleum Southwest Dushanzi Petrochemical TF1007D increased by 250 to 7,950 yuan/ton.

The daily production proportion of raffia has increased by 1.17% compared to yesterday, reaching 27.88%, while the daily production proportion of low melt copolymer has increased by 0.62% compared to yesterday, reaching 7.53%.

During the period from August 29 to September 4, 2025, the supply-demand balance remains in a state of supply exceeding demand, with the supply-demand gap staying positive and expanding compared to the previous period, exerting a bearish influence on market sentiment. In the next period, the supply-demand surplus will continue, but the gap will narrow; it is expected to still exert some downward pressure on prices.

2. Spot Overview

Table 1 Domestic Polypropylene Price Summary (Unit: RMB/ton)

Based on the East China region, today's polypropylene raffia closed at 6,848 yuan/ton, remaining stable compared to yesterday. The national average price of raffia dropped by 2 yuan/ton from yesterday, a decrease of 0.03%, in line with earlier expectations.

Futures opened lower and fluctuated in the morning. Today, the polypropylene market mainly experienced range-bound consolidation. Demand is recovering slowly, terminal procurement enthusiasm is average, and traders have slightly adjusted their offers downward. Actual transactions have seen small concessions. Coupled with the supply pressure from new upstream installations coming online, price increases lack momentum. As of midday, mainstream raffia prices in East China were at 6,750-6,950 yuan/ton.

3. Price Prediction

Supply-side pressure is increasing, and the industry chain destocking is progressing. The process is slow, and the growth rate in downstream consumer sectors is weaker than expected, leading to intensified supply-demand contradictions in the market. Factory order increments are limited, and there is insufficient willingness to stockpile. Industry players hold a cautious attitude towards the future market, resulting in a lack of upward momentum in prices. It is expected that the polypropylene market will fluctuate in the range of 6750-6950 yuan/ton in the short term.

2 Spot Overview

Based on the Changzhou market in East China, today’s cash spot pickup price for carbide-based Type V PVC in East China is 4,650 yuan/ton, unchanged from the previous trading day. 。

3、Price prediction

In the short term, there are limited changes in the domestic PVC spot market supply and demand. However, the trial of new production facilities has increased concerns about supply within the industry, and unclear foreign trade export policies are suppressing export demand. In the short term, the industry's costs remain firm, coupled with maintenance in some upstream sectors, providing strong support for the bottom price of the PVC market. It is expected that the market will maintain a stalemate in the near term, with the East China region's carbide-based Type 5 cash-in-warehouse price expected to remain in the range of 4,650-4,800 RMB/ton.

EVA producers’ inventories are at low levels, and prices remain firm at high levels. The spot market for photovoltaics continues to experience tight supply. Although the foam market is resistant to price increases, the strong support from the supply side is expected to make the market more likely to rise than fall. In the later period, the market is expected to remain mainly at a high level with limited fluctuations.

Zhejiang Petrochemical’s auction opened flat for two rounds of transactions, rising 100 RMB/ton compared to last week. In the spot market, both East China and South China saw low-level narrow fluctuations. Although upstream raw materials have risen continuously in recent days, strengthening industry cost support, there is still no favorable news regarding industry supply and demand. Market participants remain cautiously pessimistic, with mainstream players continuing to follow the trend for shipments, and downstream buyers maintaining just-in-time purchasing. Trading volumes were moderate.

3 Price prediction

Driven by cost pressures, domestic PC factories mostly maintained price support operations this week, with localized market segments seeing slight upward adjustments, while the overall market sentiment remained cautious. Recently, the overall supply in the domestic PC industry remains sufficient. The maintenance of Wanhua Chemical's PC units is nearing completion, and the second production line of Zhangzhou Chimei's PC units has commenced operation. Some manufacturers have scheduled PC unit maintenance in October, which is unlikely to boost the spot market significantly for the time being. After moderate follow-up by downstream buyers, the market may once again turn cautious. The market remains under pressure with little room for obvious improvement. It is expected that the short-term domestic PC market will mainly experience firm prices followed by a narrow range consolidation.

PET: Cost fluctuations, bottle-grade PET tends to weaken.

3. Price Prediction

Overall, demand-side procurement remains relatively rigid, and after a slight recovery in profit margins, it has limited the market’s upward potential. It is expected that polyester bottle-grade chips may follow costs and show a slightly warmer trend tomorrow. In East China, the spot price of polyester bottle-grade chips is expected to range between 5,810 and 5,900 yuan/ton.

According to Longzhong Information, the price of medium- and low-viscosity pure PBT resin in the East China market is 7,650-7,900 yuan/ton.

3 Price Prediction

The PBT market is expected to remain in a stalemate. In terms of raw materials, the performance of the terminal under the traditional PTA peak season is lukewarm, with downstream mainly engaging in just-in-time procurement. However, the short-term supply and demand remain tight, and the balance sheet continues to deplete. With low processing fees, oil prices are fluctuating strongly, providing firm support for the cost side. In the short term, there is an expectation of continued rebound in the PTA spot market. Some BDO factories have announced shutdowns for maintenance, which will increase support on the supply side, and suppliers continue to stabilize the market. Downstream purchases are on-demand, and holders are maintaining a stable and observant stance, keeping the market calm and stable. The cost support remains relatively stable, while downstream and terminal sectors follow up as needed. Many industry players are maintaining a stable and observant stance, and the market focus is expected to remain temporarily stable. The PBT market may continue its stalemate and consolidation pattern in the short term. Therefore, Longzhong expects the price of low-viscosity PBT resin in the East China market to be around 7,650-7,900 yuan/ton tomorrow.
