This week, the focus of transactions in the domestic epoxy propane market has increased. According to the monitoring system of Shengyi Society, as of November 14th, the benchmark price of Shengyi Society’s epoxy propane was 8133.33 yuan/ton, an increase of 5.63% compared to November 1st.
Price influencing factors:
Raw material side: This week, the price of raw material propylene is running strong. There is still support on the cost side, and the center of gravity of epoxy propane has shifted upward. According to the market analysis system of Shengyi Society, as of November 14th, the benchmark price of propylene in Shengyi Society was 5960.75 yuan/ton, a decrease of 1.61% compared to the beginning of this month (6058.25 yuan/ton).
Supply side: Fluctuations in the supply side have affected the temporary supply tension of epoxy propane. The tight supply situation has led to an increase in the price of epichlorohydrin.
Demand side: The downstream demand side has a decent demand for purchasing epoxy propane, with high purchasing enthusiasm and smooth shipment of epoxy propane. It is expected that the epoxy propane market will mainly operate steadily with a moderate to strong trend in the later stage.
Market forecast:
An epoxy propane analyst from Shengyi Society believes that there is still support for the market price of propylene on the raw material side, and downstream demand side has high purchasing enthusiasm, resulting in smooth shipment of epoxy propane. At present, some epoxy propane enterprises are operating at a reduced load, resulting in tight market supply. It is expected that the epoxy propane market will remain stable and strong in the short term, and more attention should be paid to changes in raw material prices and market supply and demand.

On November 14, 2025, the spot price of polyester bottle flakes rose. According to data from Shengyi Society, the average selling price of PET was 5812 yuan/ton.
Cost side strong push: Crude oil prices rebounded significantly on the day, with Shanghai SC crude oil futures reporting 461.2 yuan/barrel, up 1.50%. US crude oil and Brent crude oil also rose more than 2%, thanks to the end of the US government shutdown boosting market confidence and the positive news of additional production cuts announced by oil producing countries such as Saudi Arabia. As the upstream source of PTA, crude oil drove a significant increase in PTA futures prices on the same day. The TA2508 contract closed at 4704 yuan/ton, up 60 yuan or 1.29% from the previous day. The cost of polyester bottle chips is affected by the transmission of the crude oil PX PTA industry chain, and the collective price increase of upstream raw materials has laid a solid foundation for its price rise.
Small positive news on the supply side: PTA supply has been tight recently, with domestic PTA production decreasing by 29400 tons last week compared to the previous value, which has strengthened PTA’s supply support for downstream polyester products. Although the supply side of polyester bottle chips is generally loose, the restart rhythm of some devices after maintenance in the early stage is stable, and there is no large-scale incremental impact on the market, providing a small boost to price increases.
Weak demand side support: Currently, the industry is still in a seasonal off-season, and downstream factories are mostly rigid restocking of polyester bottle chips, lacking the willingness to stock up on a large scale, and lacking the sentiment of chasing price increases. The overall market atmosphere is strong with a wait-and-see attitude. At the same time, the orders in the terminal weaving industry are only 10-20%, and inventory continues to accumulate. This weak demand situation also limits the price increase of polyester bottle chips, making it difficult to see a significant jump.
Overall, Shengyi Society expects the polyester bottle chip market to experience narrow fluctuations in the short term, and the market trend will largely depend on the performance of the cost side. If the cost side strengthens, the price of bottle slices may slightly increase accordingly; On the contrary, it faces downward pressure.

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.
