Recently (11.1-11.13), the domestic EVA market has been weak and declining. According to the Commodity Market Analysis System of Shengyi Society, as of November 13th, the benchmark price of EVA in China was 10500 yuan/ton, a decrease of 3.37% from 10866 yuan/ton at the beginning of the month. Downstream photovoltaic and foam demand is weakening; Domestic EVA plant production has slightly decreased, but supply pressure remains; In addition, the weak downward trend in the price of raw material vinyl acetate has led to an overall weakening of the EVA market.
Recently (11.1-11.13), EVA production has slightly decreased from 9.30% at the beginning of the month to around 8.40%, indicating that supply pressure in the EVA market still exists. During the cycle, the prices of raw materials ethylene and vinyl acetate slightly decreased, and the cost faced weakened support from EVA. As of November 12th, the domestic price of ethylene in Sinopec East China was 6200 yuan/ton, a decrease of 1.59% from 6300 yuan/ton at the beginning of the month; As of November 12th, the market price of vinyl acetate in East China was 5750 yuan/ton, a decrease of 1.71% from 5850 yuan/ton at the beginning of the month.
Recently (11.1-11.13), there has been a lack of significant positive support for the demand in the EVA market, with slow follow-up of downstream photovoltaic and foam terminal orders, slow digestion of spot goods, and a decrease in ex factory prices for EVA manufacturers, resulting in a weak downward trend in the EVA market.
Future forecast: Overall, the cost support for EVA will weaken, and the demand for downstream photovoltaic and foam industries will weaken. In addition, there are plans for new equipment to be put into production in the later stage of EVA, and the overall fundamentals of EVA are weak. It is expected that the weak consolidation of EVA spot market will be the main trend in the later stage.

According to the Commodity Market Analysis System of Shengyi Society, since November, negative factors have dominated and the domestic adipic acid market has continued to weaken. On November 1st, the average market price of adipic acid was 6966 yuan/ton. On November 12th, the average market price of adipic acid in China was 6866 yuan/ton, a decrease of 1.44%.
Negative news combined with the continuous decline of domestic adipic acid market
Since November, the market for cyclohexanone, a raw material for adipic acid, and pure benzene raw materials has weakened. Due to poor demand for terminal rigidity, the transaction volume of adipic acid market has declined, and the factory price has fallen. The adipic acid market continues to weaken. As of November 12th, the mainstream market price in Shandong is around 6800 yuan/ton, and the mainstream market price in Jiangsu is 6700 yuan/ton. The average price in the domestic market fell to 6800 yuan/ton, a decrease of 200 yuan/ton from the beginning of the month, a drop of over 1%.
An analyst from Shengyi Society believes that at the end of November, the rigid demand in the terminal industry was poor, and the raw material market was weak. The market for adipic acid continued to decline weakly in the future.

According to the Commodity Market Analysis System of Shengyi Society, the domestic butadiene market first fell and then rose during this cycle, with an overall downward trend. From November 3 to November 10, 2025, the price of butadiene decreased from 7133.33 yuan/ton to 6866.67 yuan/ton, a decrease of 3.74%. The overall performance of the domestic butadiene market in this cycle is still weak. With the continuous decline in prices, it has attracted some downstream buyers to replenish inventory at low prices, driving the trading atmosphere in the spot market to improve. The spot market prices have slightly rebounded. However, due to the weak demand from downstream terminals and the bearish supply performance, the overall performance of the butadiene market is still weak under the dual negative impact.
Cost wise: According to the Commodity Market Analysis System of Shengyi Society, as of November 7th, the settlement price of the December WTI crude oil futures contract in the United States was $59.75 per barrel. The settlement price of Brent crude oil futures for January contract is $63.63 per barrel. During this round of price adjustment cycle, the crude oil price market first rose and then fell. At the beginning of the cycle, China and the United States held trade negotiations, and market risk appetite, coupled with the tense situation in South America, once supported the rise of crude oil prices; However, in the later stage of OPEC+’s new round of production increase, the market is still concerned about the long-term risk of oversupply, and the regional situation has eased. In addition, the weakening of US demand and US tariff issues have dragged down global economic and demand expectations, leading to a decline in international oil prices.
Supply side: The listed price of butadiene for various sales companies of Sinopec is 6900 yuan/ton.
On the demand side: According to the commodity market analysis system of Shengyi Society, the market situation of butadiene rubber in the northwest region is consolidating at a low level. The futures price of Shunding rubber fluctuated weakly, and the merchant’s offer was slightly adjusted. As of November 10th, the mainstream prices for butadiene rubber in Sichuan, Dushanzi, and Lande are 10300-10600 yuan/ton.
Market forecast: With the restart of some domestic facilities in October, the overall supply side is relatively loose, and the spot market prices are generally weak, attracting some downstream actively to enter the market and replenish inventory, but the overall demand is still biased towards rigid demand. The overall market expectation is still weak. With the intention of purchasing for essential needs, the spot market is operating weakly. The market lacks favorable factors to boost it, and the weak demand side is expected to lead to a weak and volatile trend in the butadiene market in the short term, with a focus on downstream procurement demand.

According to the latest market information, the polyester bottle chip market has shown an overall trend of first suppressing and then rising this week. According to data from Shengyi Society, on November 7th, the average selling price of PET was 5780 yuan/ton.
At the beginning of the week, the price of polyester bottle chips fell under pressure, mainly due to the game between low PTA processing fees and abundant spot goods, coupled with the recovery of supply side operating rates, while downstream is in the off-season with light demand. Starting from Thursday, stimulated by rumors of PX plant maintenance, the raw material side has strengthened, driving the rebound of bottle chip prices. As of November 7th, the East China market closed in the range of 5700-5800 yuan/ton, with a weekly average price of 5744 yuan/ton, a slight decrease of 0.23% compared to the previous month.
Cost driven factors led to the weakening of crude oil prices at the beginning of the week, dragging down the price of polyester bottle chips. Later, geopolitical risks drove oil prices to rebound, and cost support rebounded, driving up the price of bottle chips. The most direct trigger for Thursday’s rebound was rumors of PX plant maintenance, which increased market expectations of a tightening in raw material supply, thereby driving up bottle chip prices from the cost side.
Despite rising costs, the market supply is relatively loose in maintaining loose supply. This week, the utilization rate of domestic polyester bottle production capacity remained at 72.59%. Although some facilities in southern China are undergoing maintenance, there have also been facility restarts in eastern China, resulting in overall capacity hedging and minimal changes in supply.
The demand is currently in the seasonal off-season, and downstream demand is the main factor suppressing prices. The industry is in a seasonal off-season, and downstream factories mainly rely on rigid demand to replenish inventory, lacking enthusiasm for large-scale stocking, which restricts the upward space of bottle chip prices. The export data in September also provided evidence for the weak demand side, with the export volume of polyester bottle flakes reaching 467700 tons, a decrease of 10.18% compared to the previous month.
Overall, Business Society believes that the polyester bottle chip market will continue to fluctuate in the short term and may operate steadily with a moderate to warm trend. Main operating range: It is expected that the price will fluctuate within the range of 5700-5900 yuan/ton in the short term.
