2.Market Overview
Today, the domestic PP market remained generally stable with slight softness, with some prices dropping by 10-20 yuan/ton. In the morning, futures fluctuated and failed to provide clear guidance for the spot market. Most upstream producers kept their factory prices stable, and traders saw little change in costs, resulting in limited adjustments to quotations. In the afternoon, as futures prices declined, holders became more active in selling, and some quotations softened slightly. Downstream buyers mainly made low-priced, just-in-need purchases. Overall, market inquiries and transactions weakened compared to yesterday.
3.Key factors affecting future market price changes.
Based on the analysis of driving factors, it is expected that PP will fluctuate within a narrow range in the near term. The specific reasons are as follows:
Demand: Translate the above content into English and output the translation directly without any explanation.At present, there is still no significant improvement in new downstream orders. The operating rate has increased only slightly compared to the previous period, procurement of goods remains cautious, and support from the demand side is limited.
Supply:Recently, the second lines of Quanzhou Guoheng and Jingbo Petrochemical have restarted, with maintenance efforts on the units weakening compared to the previous period. Additionally, the stable commissioning of new units has been realized, and supply-side pressure is expected to increase.
Cost:The United States will impose more sanctions on a certain European country, and Ukraine's attacks on the energy infrastructure of this European country may disrupt supply. European and American crude oil futures have risen for four consecutive trading days, and the support from the PP cost side remains.
PVC：In Asia, the September price increase was lower than expected, and the PVC market fluctuated weakly.
1. Today's Summary
The ex-factory prices of domestic PVC producers remained generally stable, with minor adjustments in some cases.
② Maintenance at Zhenyang, Huayi, Formosa Plastics Ningbo, Zhongjia, and Huatai plant areas; Qingdao Haiwan plans to start production of new units this week.

2 Spot Overview
Table 1 Summary of Domestic PVC Spot Prices (Yuan/Ton)
Based on the Changzhou market in East China, today's spot cash price for carbide method Type V in East China is 4,770 yuan/ton, unchanged from the previous trading session.。
The domestic PVC spot market is weak and fluctuating, with fixed spot prices remaining stable for the time being. During the trading session, prices tend to decline with transactions mainly at lower levels. Insufficient policy stimulus in sectors such as real estate has led to a stalemate in the PVC supply and demand fundamentals. In September, major producers in Asia quoted prices lower than expected, putting pressure on export price competition. In East China, the cash delivery price for carbide-based Type V PVC stands at 4,720-4,850 RMB/ton, while ethylene-based PVC is priced at 4,850-5,100 RMB/ton.
3、Price forecast
In September, Asian PVC manufacturers raised their pre-sale quotations. However, the market's regional expectations were limited. There was increased competition in export prices to the Indian market, and due to the impact of anti-dumping policies, clients in the market became more cautious. The domestic spot market fundamentals remained unchanged, with upstream supply stable due to maintenance and domestic demand steady. In North China, some industries saw a slight decrease in short-term operations, contributing to an increase in inventory pressure in the market. However, the rise in cost prices provided stronger support for the bottom level. It is expected that the market will predominantly experience weak range-bound fluctuations in the short term. The cash-on-delivery prices for the carbide-based Type 5 in East China are anticipated to be in the range of 4,700-4,850 yuan/ton.
ABS：The market transaction today is average, and prices continue to show a weak trend.

1Today's Summary
This week's EVA petrochemical ex-factory prices have rebounded, and the auctioned goods sold well.
This week, the EVA petrochemical unit at Tianli Gaoxin is scheduled for shutdown, and the Hongjing PV3 unexpectedly shut down.
Table 1: Summary of Domestic EVA Prices (Unit: Yuan/Ton)
Today, the domestic EVA market is running steadily with adjustments. The supply side is stable with petrochemical firms maintaining prices firmly, and traders' offers are mainly stable. However, downstream foam factories are resistant to high-priced sources. The market is primarily focused on selling profitable inventories, with transactions centered around negotiations. Mainstream prices: Soft materials are priced at 10,900-11,400 RMB/ton, and hard materials at 10,300-11,100 RMB/ton.
3. Price Prediction
Currently, in the market, photovoltaic orders on the supply side are selling well. EVA manufacturers are mainly fulfilling previous orders, and petrochemical inventories are sufficient, supporting strong price holding. Downstream demand from the main photovoltaic sector provides good support, but foam-end users are resistant to high-priced sources. With profit-taking and a mindset of securing gains, sellers are actively shipping out goods, putting pressure on prices. Therefore, it is expected that in the short term, the EVA market may operate with stable to slightly fluctuating trends, and there is a possibility of a slight downward movement in the market.

The focus of domestic material prices mostly fell by 50 yuan/ton compared to yesterday, with some experiencing larger declines. This week, the latest factory ex-works prices for domestic PC were lowered by 50-200 yuan/ton to varying degrees. Zhejiang Petrochemical's auction opened low and concluded after three rounds, down 400 yuan/ton compared to last week. From the spot market perspective, both East and South China continued to test lower levels. Although the raw material side has temporarily stopped falling and stabilized, the cost pass-through is lagging and has not provided significant support to PC prices. The overall industry supply and demand pressure remains, market sentiment is still predominantly bearish, and trading activity is slow.
3.Price Forecasting
The raw material bisphenol A has stopped falling and started to rise again, but this has limited impact on the polycarbonate (PC) market. The PC industry is still facing strong supply and demand imbalance pressure, leading to further significant declines in market prices. The overall atmosphere remains cautious and difficult to boost, with trading becoming increasingly sluggish. In the short term, the PC market is expected to have some room for further decline. Attention should be paid to the actions of PC factories after the cost pressure transmission and changes in market sentiment.

In Chaohu, the cash ex-warehouse price is 8,550–8,650 yuan/ton.
3、Price Prediction
From the cost perspective, the caprolactam market is undergoing consolidation, and the cost pressure remains due to losses in chip profits. From the supply and demand perspective, the internal supply is decreasing, and there are plans for further production cuts by some companies in the future. However, downstream demand remains limited, with buyers mainly restocking at lower prices as needed. It is expected that the PA6 market will see slight adjustments in the near term.
PA66：Fundamentals remain stable, and the market is consolidating.
1 Today's Summary

Table 1 Summary of Domestic PA66 Prices (Unit: RMB/ton)
Based on the Yuyao market in East China, today's EPR27 market price is referenced at 15,100-15,300 yuan/ton, stable compared to yesterday's price.。 Raw material prices fluctuate, providing stable cost support. Downstream buyers purchase as needed, and market transactions are moderate, leading to a steady market trend.
3. Price Prediction
The downstream demand is weak, market supply continues to increase, and industry players lack confidence in the future market. It is expected that the domestic PA66 market will continue to fluctuate weakly in the short term.
PBT：Raw material prices fluctuate while the PBT market operates steadily with a weak trend.
1 Today's Summary

2 Spot Overview
Table 1 Summary of Domestic PBT Prices (Unit: Yuan/Ton)
The mainstream price of low to medium viscosity PBT resin in the East China region is 7,700-8,000 yuan/ton today, unchanged from the previous working day.Today, the PBT market operated steadily with a slight decline, the PTA market showed a narrow range of strength, and the BDO market weakened and declined. The raw material prices showed mixed fluctuations, providing only moderate support to PBT. The market focus continued to remain stagnant, with strong cautious sentiment among participants. According to statistics, the price of medium to low viscosity pure PBT resin in the East China market ranged from 7,700 to 8,000 yuan per ton.
3. Price Prediction
The PBT market is expected to remain in a wait-and-see mode. On the raw material side, with PTA plants in East China shutting down for maintenance, supply has dropped significantly, while demand has seen little change. The supply-demand balance is shifting further towards destocking, leading to tighter raw material supply and a stronger market focus. Driven by costs, the PTA spot market is expected to continue its relatively strong and volatile trend in the short term. For BDO, short-term supply-side support remains weak, and there is no significant increase in downstream demand. Supply pressure persists, so traders are cautious and slightly bearish, with actual deals tending to be negotiated at mid-to-low levels, and the market focus remains weak and volatile. Overall, cost-side support is mediocre. As the peak demand season approaches, market participants are likely to remain on the sidelines, with the market focus fluctuating within a range. Therefore, it is expected that the price of medium-to-low viscosity PBT resin in the East China market will be around 7,700-8,000 RMB/ton tomorrow.
PET：Costs rose first and then fell, and polyester bottle chip producers are cautious in following the price increase.
1 Today's Summary
① Some factory prices remain stable, while others have increased by 20-50 yuan/ton.

2 Spot Market Overview
Table 1 Summary of Domestic Polyester Bottle Chip Prices (Unit: RMB/ton)
Based on the East China region, the spot price of polyester bottle-grade flakes for water bottles closed at 5950 today, down 30 from the previous working day, in line with the morning expectations.
In the morning, costs fluctuated, and bottle chip transactions declined. Later, driven by the positive impact of unexpected maintenance on polyester raw material units, costs rose, and factory offers increased by 20-50 yuan accordingly. However, the willingness to chase higher prices for bottle chips was weak, resulting in a decline in transactions toward the market close. The offer range for goods from August to October was 5930-6120 yuan, with counter offers ranging from 5890 to 6030 yuan.
3. Price Prediction
The current market is dominated by the core contradiction of "cost support" and "weak demand": the supply side remains stable, with previously tight factory supply gradually easing, leading to weakened supply support; downstream peak season demand continues to be weak, with "weak chasing of price increases" becoming the norm, and purchasing only occurring at low prices for rigid replenishment. Trading activity is subdued, making it difficult to push prices upward. Although the short-term market is still driven by cost logic, the overall range is weak due to weak supply and demand. It is expected that tomorrow's spot prices for polyester bottle chips and water bottle materials in the East China market will be 5,880-5,950 RMB, slightly lower at 5,870-5,890 RMB, and slightly higher at 6,030-6,400 RMB, with a weak and volatile range. Going forward, attention should be focused on changes in raw materials.
