price trend
In terms of raw materials:
In the middle of the month, the geopolitical situation in Eastern Europe eased, and market concerns about unstable crude oil supply weakened. At the same time, OPEC+production expectations were clear, and negative factors in international oil prices have continued to this day. At the end of the month, the trend of propane followed the decline of crude oil, and the cost support for PDH manufacturing enterprises continued to weaken. The price of propylene has fluctuated narrowly, and the recent increase in enterprise load, coupled with the average follow-up of downstream demand, may drag down the future market trend. Overall, the prices of PP raw materials are showing a loosening trend in cost support.
Supply side:
At the end of August, the operating rate of domestic PP enterprises remained stable with small increases. Overall, the industry’s load level remained stable at 78%, with an average weekly total output of nearly 790000 tons. In the latter half of the year, the first and second lines of Zhejiang Petrochemical and Jingbo Polyolefin will resume work successively, coupled with the approaching production of the 900000 ton new production line in Daxie, Ningbo. The trend of loose market supply is clear, which seriously limits the support from the supply side. The current on-site supply remains abundant, with inventory levels approaching over 800000 tons and slow digestion. Overall, there has been no improvement in the support for spot prices from the PP supply side, and there are still many pressures.
In terms of demand:
At the end of August, polypropylene was in the transition period between peak and off peak seasons, and market players were looking forward to and preparing for a surge in PP demand. However, the trading atmosphere in the field remained light. Merchants have not seen large-scale advance stocking, and new orders on site still tend to be scattered and delivered according to contracts, with operations tending to be on-demand. The improvement of source liquidity is limited. The median load of downstream enterprises has slightly increased, and there is a potential willingness to build warehouses in areas such as plastic weaving, construction, and agriculture. At the same time, there are macro guidance on supply side reforms and other news, and the market has solid bottoming forces. It is recommended to closely monitor the downstream construction dynamics.
Future forecast
At the end of August, the domestic PP market prices fluctuated and consolidated. Fundamentally speaking, the upstream raw material market is weak, and the overall support for PP is weakened. The industry load is high, stable and slightly rising, with expectations of loose supply in the future, and consumption is at the junction of peak and off peak seasons. The current market is experiencing a rising atmosphere, and it is expected that there may be an upward trend during the PP peak season.

2、 Market analysis
Supply and demand situation
The price of ammonium sulfate in the domestic market has slightly decreased this week. The operating rate of coke enterprises remains stable, while the operating rate of domestic enterprises has decreased. At present, the ammonium sulfate market has sufficient supply and weak demand. Downstream demand for replenishment is increasing, with more low-priced purchases and reduced purchasing enthusiasm. The trading atmosphere in the ammonium sulfate market is light and there are currently no favorable factors.
market situation
As of August 22nd, the mainstream ex factory quotation for coking grade ammonium sulfate in Shandong region is around 1000 yuan/ton. Domestic grade ammonium sulfate, the mainstream ex factory quotation in Shandong region is around 1030-1090 yuan/ton.
3、 Future forecast
An ammonium sulfate analyst from Shengyi Society believes that the market trend of ammonium sulfate has been weak and downward recently. At present, the trading atmosphere in the ammonium sulfate market is not good, and downstream purchasing sentiment is not high. There is currently no positive news for exports. It is expected that in the short term, the domestic ammonium sulfate market price will be weak and mainly operated through consolidation.

According to the Commodity Market Analysis System of Shengyi Society, the price of domestic polyester staple fiber fluctuated upward this week (August 18-22). As of August 22, the average market price of domestic polyester staple fiber (1.4D * 38mm) was 6562 yuan/ton, up 1.4% from the beginning of the week.
Costs are gradually rising, and the domestic PTA market has slightly rebounded this week. The average price of PTA in the East China region is 4771 yuan/ton, up 1.08% from the beginning of the week. The overall fundamentals of PTA have improved, and the overseas market supply of PX on the cost side is slightly tight. The expected production of new PTA facilities at home and abroad has strengthened demand support, and PX is gradually strengthening. PTA East and South China facilities have postponed restart and shutdown due to unforeseen circumstances, optimizing their own supply structure. Downstream polyester demand is stable and there is a high volume of production and sales. Combined with the recent macro driven improvement in commodity sentiment, the PTA market price has risen slightly.
Downstream yarn factories are showing increasing resistance and maintaining a focus on replenishing essential goods. Since August, with the easing of tariffs, the orders for autumn and winter fabrics and foreign trade home textiles have gradually increased, and the operating rate of the mainstream weaving industry in Jiangsu and Zhejiang is around 52%. However, the inventory of regular greige fabrics from intermediaries and factories is still at a high level, coupled with limited overall follow-up of new orders, the space for further load increase is limited. Moreover, the actual issuance of large orders remains weak, and in this context, yarn factories prioritize the recovery of funds, making it difficult to see a significant increase in actual demand.
Business analysts believe that PTA is in a phase of improvement in supply and demand, with increased cost support, and the traditional peak demand season for September is approaching. They also have expectations for September demand. Among them, the essential orders for home clothing and bedding fabrics in early winter have been gradually released, while the autumn clothing orders have entered a concentrated delivery period, which will jointly promote the sustained recovery of the overall market atmosphere. It is expected that the short-term prices of polyester staple fibers will continue to be strong.

On the 19th, the average market price of acetic acid was 2400 yuan/ton, an increase of 30 yuan/ton or 1.27% from the price of 2370 yuan/ton on August 11th. Since mid August, the domestic acetic acid market has mainly operated weakly, mainly due to the high utilization rate of on-site production capacity and the maintenance of high market supply. However, the downstream market is weak, and the enthusiasm for entering the market for purchasing is not high. The demand side support is limited, and the market supply-demand contradiction is deadlocked, with prices in most areas maintaining low levels; On the 19th, the supplier announced that the equipment of manufacturers in Central China has been shut down, and the factory prices have increased significantly. Market prices in other regions have also kept up with the increase.

As of the 19th, the average price in the domestic market was 2301.67 yuan/ton, a decrease of 3.39% compared to the price of 2382.50 yuan/ton on August 11th. During the cycle, the social inventory of ports continues to accumulate, and the mentality of operators is bearish. The demand for spot methanol market is weak, downstream acceptance of high prices is not smooth, the market trading atmosphere is poor, and the focus of the methanol market continues to decline.
The downstream acetic anhydride market has slightly decreased, with the average ex factory price of acetic anhydride dropping from 4092.50 yuan/ton to 4082.50 yuan/ton from August 11th to 19th, a decrease of 0.24%. The trading atmosphere in the upstream acetic acid market is weak, with insufficient support for acetic anhydride. Downstream buyers follow up on demand, and the market trading atmosphere is weak. The supply and demand in the acetic anhydride market are deadlocked, and the price of acetic anhydride fluctuates slightly during the cycle.
Market forecast: Business Society’s acetic acid analyst believes that the utilization rate of domestic acetic acid production capacity remains high, and the market inventory is sufficient. Although the supply news has boosted the mentality of industry players, downstream demand is poor, and enterprise shipments are limited. The situation of oversupply in the market still exists in the short term. It is expected that the acetic acid market will weaken and consolidate in the later stage, and downstream follow-up will be closely monitored in the future.
