According to the Commodity Market Analysis System of Shengyi Society, the price center of polyester filament has been partially raised. As of August 11th, the POY (150D/48F) quotation of mainstream polyester filament factories in Jiangsu and Zhejiang is between 6600-6800 yuan/ton, the DTY (150D/48F low elasticity) quotation is between 7800-8050 yuan/ton, and the FDY (150D/96F) quotation is between 6900-7200 yuan/ton.
Over the weekend, the production and sales rate of polyester filament factories rebounded, and inventory pressure eased (factory inventory increased by 8.84% to 19.7 days per week), prompting manufacturers to tentatively raise prices. As August approaches the traditional textile peak season, downstream textile city transactions have rebounded month on month (Keqiao Textile Index raw material prices increased by 1.15% month on month), boosting market confidence. The willingness of major enterprises to jointly reduce production and repair profits is strong, supporting price stabilization. On the demand side, the weaving operation rate is 55.75%, and the raw material stocking days are 9.39 days, still at a low level, but the autumn fabric orders have begun to increase slightly.
Business Society believes that the market is in a game of weak reality and strong expectations, and is expected to operate steadily with a moderate to strong trend. The fluctuation of crude oil has narrowed (Brent $66.59/barrel), and the impact on the cost side has weakened; If the downstream “Golden September and Silver October” stocking is launched, polyester prices may slightly increase.

1、 Price trend
According to the monitoring of the commodity market analysis system of Shengyi Society, the PVC spot market fluctuated within a range this week (8.4-8), with prices rising within the week and then falling back. As the weekend approached, prices basically returned to the level at the beginning of the week. As of Friday, the average price of SG-5 PVC carbide method in China was 4780 yuan/ton, with a slight increase of 0.61% during the week.
2、 Market analysis
This week, most PVC manufacturers maintained price stability, with some making slight adjustments within 50 yuan/ton. Due to the lack of favorable fundamentals, crude oil prices have weakened and fallen, and the futures market has experienced repeated range fluctuations, making it difficult to maintain a long-term strong pattern. After the PVC price rose at the beginning of the week, it stopped rising and slightly fell back, with a weak price and a slight downward shift in the overall range. From the perspective of supply and demand fundamentals, the spot PVC market has shown loose supply and demand, and most manufacturers are operating stably. The supply pressure has not changed much, dealers’ offers are generally weak, downstream demand performance is insufficient, downstream procurement is mainly based on spot prices, inquiry and procurement enthusiasm is not high, and the market atmosphere is sluggish. The hanging order price is relatively low. Overall, it is still mainly driven by basic needs, and the trading atmosphere is average. As of now, the quotation range for PVC SG5 electrical aggregate in China is mostly around 4850-5000 yuan/ton.
In terms of upstream calcium carbide, the calcium carbide market rebounded this week, with a slight increase in prices. According to the commodity analysis system of Shengyi Society, the increase this week was 1.4%. But since August, the market has been volatile, with a comprehensive increase or decrease of 0. The price is still relatively low, with limited support for PVC.
3、 Future forecast
The PVC analyst from Shengyi Society believes that the PVC spot market is average, mainly due to insufficient downstream operating rates and average demand. The supply-demand pattern is difficult to change in the short term, and it is expected that PVC prices will continue to maintain a range adjustment pattern next week.

Price trend: (8.1-8.7)
First up, then down: At the beginning of the week, there was a brief rally at the end of July, but downstream acceptance was low. Subsequently, supply pressure increased, and companies lowered prices to promote transactions.
Significant decline: According to the monitoring of the commodity market analysis system of Shengyi Society, as of August 7th, the average price of dichloromethane in Shandong Province was 2075 yuan/ton, a decrease of 5.36% during the week and a year-on-year decrease of 22.28%.
analysis of influencing factors
Supply side: The operating rate has rebounded, and inventory pressure has become apparent
Device dynamics: Enterprise production has rebounded, and the overall industry production has risen to around 80%, with loose supply.
Inventory pressure: Downstream procurement is weak, companies are reducing prices to reduce inventory, and some manufacturers are experiencing slightly slower inventory pressure.
Cost side: methanol drops, liquid chlorine rises, insufficient cost support
The inventory of methanol at the port is high, and the market fluctuated weakly during the week. As of August 7th, the benchmark price of methanol at Shengyi Society was 2383.33 yuan/ton, a decrease of 0.42% during the week.
Liquid chlorine: Supply in Shandong has tightened, downstream shipments have increased, and prices have slightly increased, but the impact on dichloromethane is limited.
On the demand side: seasonal suppression, with rigid procurement as the main focus
The purchasing enthusiasm of downstream refrigerant, pharmaceutical and other industries is average, with replenishment mainly based on demand, and no significant increase in volume has been observed. Due to factors such as high temperatures and power restrictions, the operating rate in some areas has slightly decreased, suppressing the release of demand.
Future prospects
Supply is relatively loose, and prices are expected to fluctuate at a low level. If downstream demand recovers or exports increase, the market may rebound slightly. Attention should be paid to device dynamics, inventory changes, export order status, etc.

According to the commodity analysis system of Shengyi Society, the market for locally refined petroleum coke continued to rise in July. The mainstream average price of petroleum coke products from major domestic refineries was 2390 yuan/ton on July 31 and 2257.50 yuan/ton on July 1, with a monthly increase of 5.87%.
Cost wise: The crude oil market fluctuated and rose in July. In mid to early July, OPEC+released its annual world oil outlook and lowered its energy demand expectations, putting pressure on oil prices. In addition, the geopolitical situation in the Middle East has led to increased sanctions against Russia by the United States. Starting from August 1st, the United States will impose a 30% tariff on most imported goods from the European Union and Mexico, causing fluctuations in the international crude oil market; In late July, the United States and the European Union reached a new trade agreement, and the United States may impose new sanctions on Russia. Additionally, concerns about US tariffs continue to weaken, and crude oil prices continue to rise.
Supply side: In mid to early July, the shipment of petroleum coke from local refineries was still acceptable, and downstream demand for carbon for aluminum remained stable. The stocking operation of negative electrode materials was active, and coupled with low inventory of petroleum coke in some refineries, it was favorable for the petroleum coke market, resulting in an overall increase in petroleum coke prices; In late July, the market for refined petroleum coke remained stable, with decent shipments from refineries. However, prices of petroleum coke from some refineries fluctuated significantly with indicators, with fluctuations in prices; The demand from downstream enterprises is relatively stable, and the benchmark price for purchasing pre baked anodes in August has dropped by 10 yuan/ton compared to July, indicating average enthusiasm for purchasing petroleum coke. In July, the transaction of petroleum coke at the port was average, with stable shipments and sufficient inventory at the port. Downstream enterprises maintained their essential procurement needs.
On the demand side, the domestic silicon metal (# 441) market experienced a broad upward trend in July. During the month, the market prices of metallic silicon (# 441) in many regions of China have continuously adjusted upwards, and the overall focus of market negotiations has continued to rebound. This is also the first consecutive downturn in the market since the beginning of the year. Silicon companies in the northern region have reduced production of equipment, while the southern region has entered a period of abundant water. The overall pace of resuming production is normal, and market supply is decreasing in the north and increasing in the south, resulting in an overall increase in supply and output. The demand for petroleum coke market in the silicon industry still exists.
The overall price of medium sulfur calcined coke rose in July, with the calcination market remaining stable in mid to early July. In late July, the cost of petroleum coke prices rose overall, with some manufacturers adjusting their prices.
Market forecast: There is still purchasing demand downstream of petroleum coke to support the petroleum coke market in August, but refinery operations have increased compared to July. In addition, with the recent arrival of imported petroleum coke at the port, the market supply is relatively sufficient, and it is expected that petroleum coke will mainly fluctuate and consolidate in August.

According to the commodity analysis system of Shengyi Society, in early August, the hydrogen peroxide market weakened and fluctuated downwards. On August 1st, the average market price of hydrogen peroxide was 696 yuan/ton, and on August 4th, the average market price of hydrogen peroxide was 690 yuan/ton, a decrease of 0.96% in price.
Negative sentiment still persists, with a slight decline in the hydrogen peroxide market
At the beginning of August, the terminal demand in the printing and papermaking industry fell, and some manufacturers of hydrogen peroxide stopped for maintenance, easing the supply pressure. The long short game weakened the hydrogen peroxide market, and the average price in the domestic market fell to around 690 yuan/ton, with a price drop of about 10 yuan/ton. The market transactions are average, and the market is weak and declining.
The hydrogen peroxide analyst from Shengyi Society believes that in mid August, the demand for terminal printing and papermaking industry will weaken, and the pressure on hydrogen peroxide supply will still exist. The future market will continue to weaken.
