According to the monitoring of the commodity market analysis system of Shengyi Society, the average price of LLDPE (7042) was 7346 yuan/ton on June 9th and 7471 yuan/ton on June 17th, an increase of 1.70%. LDPE (2426H) had an average price of 9216 yuan/ton on June 9th and 9683 yuan/ton on June 17th, an increase of 5.06%. HDPE (2426H) had an average price of 8037 yuan/ton on June 9th and 8075 yuan/ton on June 17th, an increase of 0.47%.
The recent trend of polyethylene market is relatively strong, with a relatively large increase in high-pressure prices. Affected by the tense situation in the Middle East, international oil prices have risen, and the cost side is favorable for the rise in the polyethylene market. Petrochemical companies and traders have adjusted their prices accordingly. Especially for high-pressure products, the dependence on imports is high, and the market is concerned that the supply may be insufficient; At the same time, there are many high-pressure product equipment shutdowns for maintenance, including Yanshan Petrochemical, Wanhua Chemical, and Zhejiang Petrochemical. The demand for agricultural film is in the off-season, with few orders from enterprises, poor demand, and limited transactions; The operating rate of packaging film enterprises is expected to decrease, and demand is weak, which limits the price increase space on the demand side.
Due to the expected decrease in costs and supply side, but the demand side is in the off-season, and it is expected that the trend of polyethylene will be mainly strong, with limited upward space.

Last week (June 9-15, 2025), the upstream cost side support for nylon filament was relatively strong, but downstream enterprises had poor purchasing power and weak demand. Downstream manufacturers held multiple rigid demand purchases, and industry players held a cautious and wait-and-see attitude. The nylon filament market was weakly consolidating and operating, with prices slightly falling.
Nylon filament prices are weak and falling
According to the Commodity Market Analysis System of Shengyi Society, last week (June 9-15, 2025), the price of nylon filament was weak and slightly decreased. As of June 15, 2025, DTY (premium product) of nylon filament in Jiangsu region; 70D/24F) quoted 14600 yuan/ton, a decrease of 160 yuan/ton from last week, a weekly decrease of 1.08%; Nylon POY (premium product; 86D/24F) quoted 12150 yuan/ton, a decrease of 150 yuan/ton compared to last week, with a weekly decrease of 1.22%; The price of nylon FDY (premium product: 40D/12F) is reported at 15225 yuan/ton, a decrease of 175 yuan/ton from last week, with a weekly decline of 1.14%.
The raw material market is operating relatively strongly
In terms of cost: Last week (June 9-15, 2025), the spot market price of caprolactam was relatively strong during the week, and the weekly settlement price of Sinopec’s high-end caprolactam was raised to 9650 yuan/ton. The market for nylon PA6 chips also saw a slight increase, with strong cost support. As of June 15, 2025, the benchmark price of caprolactam in Shengyi Society was 9325 yuan/ton, with a slight increase in price and a weekly increase of 1.47%. During the week, the market price of high-speed spun nylon PA6 slices slightly increased, with a weekly increase of 0.95%, mainly due to strong cost support.
Supply and demand: During the week, some nylon filament manufacturers have lowered their operating rates, resulting in a decline in overall market supply. However, industry inventory levels continue to increase, leading to poor performance on the supply side; The demand in the end market is weak, and some downstream manufacturers have reduced production or switched production, resulting in a decrease in demand for nylon filament. It is difficult to find favorable support from the demand side, and many parties are following suit with rigid demand. Many industry players are adopting a cautious and wait-and-see attitude.
Future forecast
Cost aspect: Caprolactam is operating strongly, and prices will rise. In terms of nylon PA6 chips, due to strong cost support, the supply level of PA6 chips in the market may continue to improve. Downstream market demand is weak, and it is expected that the market price of nylon PA6 chips will rise slightly.
Supply and demand: June is a transitional period from the market to the traditional off-season, coupled with the lack of signs of improvement in terminal market demand and low purchasing enthusiasm in downstream markets. Therefore, it is expected that the demand for nylon filament market may decrease next month. If there is no significant improvement in demand, under the pressure of large inventory, some nylon filament manufacturers may have the possibility of reducing production capacity, while the industry continues to release new production capacity. Therefore, it is expected that the supply of nylon filament market will decrease next month.
Overall, the upstream raw material caprolactam spot market and nylon PA6 chip market will operate strongly, with strong cost support. The downstream market demand is difficult to improve, and the demand side will drag down the market trend. Business analysts predict that the short-term nylon filament market price will follow the raw material to rise slightly, but the increase is limited, with an expected increase of 100-300 yuan/ton.

Aluminum prices have risen this week. According to the Commodity Market Analysis System of Shengyi Society, as of June 13, 2025, the average price of aluminum ingots in the East China market in China was 20740 yuan/ton, an increase of 2.15% from the market average price of 20303.33 yuan/ton on June 1.
Fundamental Overview
Currently in the off-season of demand, downstream operating rates are low, and the supply and demand of aluminum ingots are relatively weak.
On the supply side, the operational capacity of electrolytic aluminum has slightly increased, resulting in a slight increase in output. As of June 12th, the weekly production of mainstream domestic manufacturers remained around 843000 tons.
On the demand side, during the off-season of traditional consumption, the demand for building profiles, home appliances, and other products is relatively weak. Although new energy vehicles can drive some of the demand, the photovoltaic market has experienced a decline in production and overall demand growth is weak.
On the cost side, the price of alumina has fallen, and the cost center of electrolytic aluminum has shifted downwards, weakening the support for aluminum prices.
Social inventory: Currently, the social inventory of aluminum ingots is relatively low and in a state of destocking. As of June 12th, the inventory of electrolytic aluminum ingots in mainstream consumption areas in China was 463000 tons, a decrease of 18000 tons from the beginning of this week; A decrease of 45000 tons compared to June 5th.
Recent upward momentum
During the export window period after tariff adjustment in June, the rush to export will provide some support for aluminum prices.
Future expectations
At present, the market trading logic tends to be macro oriented, and may later shift to fundamentals. With the expectation of a subsequent consumption off-season, the upward space for aluminum prices will narrow.

The cyclohexanone data analyst from Shengyi Society predicts that the short-term cyclohexanone market will mainly operate steadily with small to medium growth, and specific changes in supply and demand information need to be closely monitored.

Recently (6.1~6.11), the butadiene rubber market has fluctuated and weakened. According to the commodity market analysis system of Shengyi Society, as of June 11, the butadiene rubber market price in East China was 11650 yuan/ton, a decrease of 2.18% from 11910 yuan/ton on the 1st. The price of raw material butadiene continues to decline, and the cost center of butadiene rubber shifts downwards; Shunding rubber production slightly decreased, easing supply pressure; Downstream tire production slightly decreased, providing support for the demand for butadiene rubber. As of June 11th, the mainstream prices in Qilu, Daqing, Sichuan, and Yangtze Shunding in East China were reported at 11550-11800 yuan/ton.
Recently (6.1~6.11), the price of butadiene has continued to decline, and the cost center of butadiene rubber has shifted downwards.
