As of Friday, April 17, 2026, the polyester bottle chip market has shown a fluctuating upward trend of “low at the beginning of the week, rebound in the middle of the week, and firm over the weekend” this week (April 13 April 17). The core is dominated by strong cost support and tight spot prices, but downstream demand is weak and transactions are limited.
1、 This week’s price data (according to data from Shengyi Society, the mainstream transaction price for East China water bottle grade)
At the beginning of the week (4.13-4.14): 8450-8550 yuan/ton Due to a slight drop in oil prices and downstream wait-and-see effects, the market was weakly consolidating.
Mid week (4.15-4.16): PTA maintenance at a price of 8550-8700 yuan/ton is beneficial for fermentation, leading to increased costs and rising prices from manufacturers.
On the weekend (4.17), the spot supply was tight at 8600-8750 yuan/ton, but the quotation remained firm, with a weekly average price of about 8580 yuan/ton.
2、 Analysis of Core Driving Factors
1. Cost side: Leading the rise (strong support)
Crude oil: The situation in the Middle East is volatile, with Brent fluctuating sharply at high levels of $110-120 per barrel, and the overall center of gravity is relatively high.
PTA: Large factories are conducting centralized maintenance, with strong expectations of tight supply and rising prices, directly increasing the production cost of bottle chips.
2. Supply side: Shortage of spot goods (secondary support)
The industry’s operating rate is about 72.95%, with some devices still undergoing maintenance and limited market supply.
The manufacturer’s inventory is low (about 10.28 days), and there is a strong willingness to sell and raise prices.
3. Demand side: Weakness and fatigue (mainly suppressed)
Downstream beverages, sheets, and other products have low acceptance of high prices, and their purchases are mostly small orders for essential needs and on-demand purchases.
Although it is the peak season, the cost increase is too large, downstream resistance, and overall transaction volume is light.
3、 Outlook for next week (from April 20th)
Price range: expected to fluctuate at a high level between 8500-9300 yuan/ton.
• Main logic:
Good news: PTA maintenance continues, cost support remains strong, and the tight spot market pattern is difficult to change.
Negative: Downstream continues to resist high prices, making it difficult to increase demand for essential goods.
Conclusion: Easy to rise but difficult to fall, with strong fluctuations, the weekly average price may slightly rise to 8680 yuan/ton.

According to data from Shengyishe Spot News, in early April, the hydrogen peroxide market showed an oscillating upward trend, with demand improving and the hydrogen peroxide market steadily heating up. At the beginning of the month, the average price of hydrogen peroxide market was 796 yuan/ton. On April 16th, the average price of hydrogen peroxide market was 810 yuan/ton, an increase of 1.67%.
Reasons affecting the rise of hydrogen peroxide market
Positive factors
Demand side: Concentrated release of downstream demand. Main downstream epoxy propane enterprises maintain continuous procurement; At the same time, the workload of the caprolactam industry has increased, and downstream industries related to new energy such as papermaking and iron phosphate have also conducted centralized procurement, jointly driving up market trading heat.
Inventory and supply situation: The market supply side is showing a tight pattern. The latest data shows that under the digestion of strong demand, the inventory of enterprises in the main production areas is at a low level. Although some devices have maintenance plans, there are also new devices facing production, resulting in narrow fluctuations in overall supply.
Negative factors
Supply side: Pressure from weak local market demand or oversupply, medium – to long-term capacity expansion expectations: Liuhua Group announced an investment of approximately 290 million yuan to construct new projects, expected to significantly increase its 27.5% hydrogen peroxide production capacity from 160000 tons/year to over 360000 tons/year. Although new production capacity has not yet been implemented, the market has begun to digest the expectation of a significant increase in future supply, creating medium to long-term downward pressure on spot prices.
News: Some hydrogen peroxide producers are at risk, which may undermine market confidence in the industry as a whole and reflect the dilemma of sluggish industry demand in 2025.
Technical Prediction of Business Society’s Hydrogen Peroxide Spot Analysis: From the price trend chart of Business Society’s hydrogen peroxide, it can be seen that the key indicator is that in early March, the 10 day moving average of hydrogen peroxide crossed the 20 day moving average, and hydrogen peroxide showed an upward trend. On April 12th, the 10 day moving average of hydrogen peroxide crossed the 20 day moving average, and the spot market for hydrogen peroxide continued to fluctuate and rise in early April. The probability of a price increase for hydrogen peroxide in the latter half of the year is relatively high.
Auxiliary indicators: In early April, the price of hydrogen peroxide was at a 30 day high, a 20 day high, and a 30 day rise, indicating that in the long run, the upward space of the hydrogen peroxide market is limited.
In summary, in late April, the fundamentals of domestic hydrogen peroxide remained mixed with long and short positions, and the pressure of loose supply remained, with some improvement in terminal demand.
From a technical perspective, it can be seen that the hydrogen peroxide market was at a high level in early April, with limited upward potential. In late April, the overall market for hydrogen peroxide fluctuated widely, with a high probability of decline. The expected price is between 750 yuan/ton and 800 yuan/ton.

In the first half of April, the TDI market in East China first rose and then fell, with gains giving up. As of April 14th, the average market price in East China was 20100 yuan/ton, and as of April 1st, the average price was 20200 yuan/ton, a decrease of 0.5% during the period and an increase of 81.63% year-on-year. Due to high prices, downstream resistance is evident, demand is sluggish, and market transaction prices have loosened.
Supply and demand side: Domestic facilities such as Wanhua maintain medium to high load operation, market inventory is low, domestic demand is average, and foreign demand is good.
On the cost side: The toluene market fluctuates with crude oil prices, with downstream demand for replenishment and average gas purchases, causing toluene prices to fluctuate and decline.
Overall, the TDI market currently has ample supply, weak domestic demand, export support, and low inventory levels, which interact with each other to minimize price fluctuations. Based on the spot market analysis of Shengyi Society, the 10 day moving average and the 20 day moving average have overlapped, indicating that the market has reached a turning point and the price position is high, with limited upward space. TDI prices may be weakly stabilized and consolidated.

According to data from Shengyi Society, the domestic butadiene rubber market has been rising for five consecutive months since November 2025, with the highest price reaching 18140 yuan/ton on April 7th, an increase of 62.69%. As of April 14th, the market price of butadiene rubber was 16640 yuan/ton, a decrease of 8.27% from its peak.
From November to December 2025, the supply of butadiene rubber in the market will shrink slightly, and the demand for essential goods will be weak, resulting in a slight increase in butadiene rubber prices at the bottom. On the supply side, the average operating load of domestic Gaoshun Shunding rubber plants reached 71.44%, and some enterprises stopped for maintenance; On the demand side, downstream tires with all steel tires have started production at around 6.30%, and semi steel tires have started production at around 7.10%, providing overall demand support, but high priced transactions are weak. ​
Starting from January 2026, the market growth rate of butadiene rubber will gradually expand. The core driving factors are concentrated in three aspects: firstly, the downstream actively stocked up before the Lunar New Year, and the tire production rebounded significantly after the holiday, which supported the demand for butadiene rubber; At the end of February, the Middle East conflict led to high international crude oil prices, widening the supply gap of butadiene and driving up the production cost of butadiene rubber; The combination of routine maintenance and rising costs in three enterprises has led to passive production cuts due to losses, further exacerbating supply shortages. ​
From the perspective of the Shunding Rubber Index on Shengyi Society’s spot trading platform, starting from mid November 2025, the price curve of Shunding rubber will successively cross the 10 day, 20 day, 30 day, and 60 day moving averages, ushering in a 5-month upward cycle for Shunding rubber.
In early April, with the news of the US Iran negotiations, the bullish sentiment in the butadiene rubber market gradually weakened, and the price of butadiene rubber fell from a high level. However, due to some equipment still undergoing maintenance or negative load reduction, the extent of butadiene rubber’s decline was limited under tight supply conditions.
Future forecast
Looking ahead to the future, from an industrial perspective, although the current Middle East conflict has cooled down in the short term, the shipping problem has not been substantially resolved. In addition, the shortage of raw material butadiene has not eased, the supply contraction pattern continues, and downstream tire demand remains stable. Therefore, there is still support for butadiene rubber in the short term. In the medium to long term, with the release of new domestic butadiene production capacity, the tight supply situation is expected to ease. In addition, with the resumption of production of butadiene rubber plants and the commissioning of new production capacity, prices may face downward pressure.

According to the Commodity Market Analysis System of Shengyi Society, from April 6th to 13th (as of 15:00), the price of methanol in the East China port market in China first increased from 3490 yuan/ton and then fell to around 3360 yuan/ton, with a price drop of 3.72% during the cycle, a month on month increase of 18.62%, and a year-on-year increase of 35.39%. The domestic methanol market trading is still mainly influenced by geopolitics, and the rising sentiment on the futures side is gradually transmitted to the spot market; Supported by the continuous destocking of enterprises, the increasing demand for locally sourced olefins, and the gradual recovery of downstream demand, methanol prices have shown a significant surge.
As of the close on April 13th, the closing price of methanol futures on Zhengzhou Commodity Exchange has risen. The main contract for methanol futures, 2605, opened at 3089 yuan/ton, with a highest price of 3300 yuan/ton and a lowest price of 3043 yuan/ton. It closed at 3175 yuan/ton in the closing session, up 27 yuan/ton or 0.86% from the previous trading day’s settlement. The trading volume is 1584666, the position is 361418, and the daily increase is -56991.
On the cost side, the overall supply of coal is stable, and downstream procurement enthusiasm is not high. Coal prices are mainly stable, and the cost side is stable. The cost impact is mixed.
On the demand side, from the downstream perspective, methanol prices continue to rise significantly. Although there has been a decline, the weekly average price remains high. Some downstream industries are struggling to keep up with the trend, and negative feedback from end products is becoming increasingly severe, resulting in a passive narrowing of production profits for most downstream industries. Most downstream products are affected by methanol prices, and the demand for methanol is biased towards favorable factors.
Supply side, some enterprise equipment maintenance; Some enterprises have restored their equipment; The overall recovery exceeds the loss, resulting in an increase in production and a rise in capacity utilization. Negative factors affecting the methanol supply side.
In terms of external trading, as of the close on April 10th, the CFR Southeast Asian methanol market closed at $679-681/ton, down $10/ton. The FOB US Gulf methanol market closed at 141-143 cents per gallon; The European FOB Rotterdam methanol market closed at 510-512 euros/ton, down 9 euros/ton.
In the future forecast, with the support of fundamental factors such as tight supply and demand patterns and continuous inventory depletion, although the price increase has slowed down, the overall trend will remain strong. Overall, the methanol analyst from Shengyi Society predicts that the domestic methanol spot market will be mainly dominated by strong consolidation.
