According to the Commodity Market Analysis System of Shengyi Society, the price center of polyester filament has been partially raised. As of August 15th, the POY (150D/48F) quotation of mainstream polyester filament factories in Jiangsu and Zhejiang is between 6600-6900 yuan/ton, the DTY (150D/48F low elasticity) quotation of polyester is between 7800-8050 yuan/ton, and the FDY (150D/96F) quotation of polyester is between 7000-7200 yuan/ton.
In terms of cost, on August 15th, international crude oil futures rose by 1.77% (WTI $63.96/barrel, Brent $66.84/barrel), and PX (p-xylene) prices rose synchronously to $833.67/ton. Costs were transmitted to PTA (polyester raw materials), and PTA futures settlement prices rose by 0.6% to 4708 yuan/ton, boosting confidence with the rebound of crude oil. PTA processing fees have been expanded to over 200 yuan/ton, while FDY’s cash flow losses still reach -487 yuan/ton. Manufacturers have raised prices to restore profit margins.
In terms of supply and demand, polyester factories maintain a high operating rate of over 90%, but leading enterprises regulate the market through centralized production cuts (such as FDY capacity utilization being lower than the industry average), coupled with limited new capacity added in August, temporarily easing supply pressure. Terminal textile orders have not yet substantially rebounded, with weaving enterprises holding 36.8 days of raw fabric inventory, and procurement mainly focused on essential needs. In mid to late August, the traditional off-season comes to an end, and the strength of demand recovery needs to be observed in the launch of “Golden September and Silver October” orders. The psychology of buying up rather than buying down dominates, and manufacturers create expectations of price increases by continuously raising prices, forcing downstream customers to passively purchase goods.
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 volatility of crude oil is expected to narrow (Brent $66.59/barrel), and the impact on the cost side is expected to weaken; If the downstream “Golden September and Silver October” stocking is launched, polyester prices may slightly rise, but in the short term, the upward space is limited.

This week, the domestic epoxy propane market price has remained stable temporarily. According to the monitoring system of Shengyi Society, as of August 14th, the benchmark price of Shengyi Society’s epoxy propane was 7633.33 yuan/ton, a decrease of 6.5% compared to the beginning of the month.
Price influencing factors:
Raw material side: This week, the price of raw material propylene has decreased, resulting in a decrease in the production cost of epoxy propane, reducing price support and intensifying downward pressure on prices. It is expected that the epoxy propane market price will fluctuate weakly in the later stage. According to the market analysis system of Shengyi Society, as of August 14th, the benchmark price of propylene in Shengyi Society was 6633.25 yuan/ton, an increase of 3.11% compared to the beginning of this month (6433.25 yuan/ton).
Supply side: The market supply has significantly increased, expected to reach around 19000 tons. Overall, the supply of epichlorohydrin is showing a loose trend, which has increased the competitiveness of the industry. It is expected that the price of epichlorohydrin will consolidate in the near future.
Demand side: The downstream trading atmosphere of epoxy propane is average, and the purchasing enthusiasm is relatively flat, mainly consuming previous orders. Overall, the demand is facing weak support from the epoxy propane market, and the market may mainly consolidate in the later stage.
Market forecast:
An epoxy propane analyst from Shengyi Society believes that the concentrated release of production capacity in the epoxy propane market has led to a relatively loose supply side and a decline in raw material prices. In addition, downstream markets have a strong demand for purchasing, resulting in an average trading atmosphere. It is expected that the epoxy propane market will mainly consolidate in the short term, and more attention should be paid to changes in raw material prices and upstream and downstream supply and demand.

According to the Commodity Market Analysis System of Shengyi Society, the domestic natural rubber spot market has seen a slight upward trend recently (8.1-8.11). As of August 11th, the spot rubber market price in China’s natural rubber market was around 14816 yuan/ton, an increase of 2.48% from 14458 yuan/ton on the first day. On the one hand, the downstream tire production is basically stable, which provides essential support for Tianjian; On the other hand, the price of natural rubber raw materials remains strong, and the cost support of natural rubber continues; In addition, the slight decrease in domestic port inventory and the improvement of market atmosphere have driven natural rubber prices to fluctuate and rise. As of August 11th, the mainstream price for 24 years of Guangken, Baodao, and Haibao latex in Qingdao area is 14700-14950 yuan/ton.
As of August 11th, the price of Thai glue was 54.00 baht/kg, unchanged from the beginning of the month. On the one hand, local heavy rainfall and gust warnings in early and mid August in Thailand have posed resistance to natural rubber (TSR) cutting activities. On the other hand, the domestic cutting period, coupled with the unstable production of old natural rubber plantations in Vietnam, has provided short-term support for the price of TSR raw materials.
Recently (8.1-8.11), natural rubber inventory has been slightly reduced, and the market atmosphere has improved. As of August 10, 2025, the total inventory of Tianjiao bonded and general trade in Qingdao area was 619900 tons, a decrease of 11900 tons or 1.89% compared to the previous period.
Recently (8.1-8.11), the overall stability of downstream tire production has provided essential support for the natural rubber market. As of August 8th, the construction of semi steel tires by domestic tire companies has slightly increased to around 7.20%; The construction of all steel tires by tire companies in Shandong Province has slightly increased to around 6.3%.
Market forecast: The current high prices of raw materials both domestically and internationally, as well as stable downstream tire production, provide support for the Tianjin rubber market. The slight decrease in Tianjin rubber port inventory is expected to lead to a certain recovery in the Tianjin rubber market. Overall, with the arrival of the peak season, it is expected that the natural rubber market will fluctuate and rise in the later period.
