This week (April 14-18, 2025), the center of gravity of raw material prices has fallen again, and the market price of nylon filament has followed suit. Sinopec’s high-end caprolactam price was lowered to 10080 yuan/ton last week, and the high-speed spinning market for nylon PA6 chips continued to decline, with weak cost support; During the week, the operating load of some nylon filament manufacturers’ facilities decreased, resulting in a narrow decline in industry supply. Some manufacturers had high inventory levels, and the performance of the supply side was average; There are few orders in the terminal market, and some downstream manufacturers are reducing production and taking holidays. Other manufacturers are holding on to their essential needs, resulting in limited on-site transactions and a sluggish demand side. Overall, the upstream raw material market is weak and declining, with some on-site inventory levels at high levels. Downstream companies have average purchasing power, and negative factors in the market dominate. The price pressure on the nylon filament market continues to decline.
According to the Commodity Market Analysis System of Shengyi Society, the price of nylon filament continued to decline weakly this week (April 14-18, 2025). As of April 18, 2025, the price of nylon filament DTY (premium product; 70D/24F) in Jiangsu region is 15480 yuan/ton, a decrease of 100 yuan/ton from last week, a weekly decrease of 0.64%; Nylon POY (premium product; 86D/24F) is priced at 12900 yuan/ton, a decrease of 200 yuan/ton or 1.53% from last week’s price; The price of nylon FDY (premium product: 40D/12F) is reported at 16075 yuan/ton, a decrease of 150 yuan/ton from last week, with a weekly decline of 0.92%.
The raw material market is weak and declining
In terms of cost: Sinopec’s high-end caprolactam weekly closing price has been lowered. As of April 18, 2025, the benchmark price of caprolactam in Shengyi Society is 9660 yuan/ton, with a weekly decline of 5.45%. During the week, the market price of high-speed spun nylon PA6 chips fell sharply, with a 2.01% drop in nylon PA6 prices, indicating weak cost support.
Supply and demand: This week (April 14-18, 2025), the operating rate of the nylon filament market equipment did not fluctuate much, the industry supply was at a high level, some manufacturers had high inventory levels, downstream market demand was light, and some nylon filament prices were not smooth for shipment. Many were sold at discounted prices, and the overall profit situation of the market was still not optimistic.
Future forecast
Cost aspect: In terms of caprolactam, the trend of raw material pure benzene is average, and the supply of caprolactam market may recover to some extent. The purchasing enthusiasm of the demand side is not good, and it is expected that the market price of caprolactam will slightly decline next week. In terms of nylon PA6 slicing, there is insufficient cost support, and there is no significant improvement in terminal demand. Downstream manufacturers are cautious in purchasing for essential needs, and it is expected that the nylon PA6 slicing market will continue to decline next week. Therefore, it is expected that the price trend of the raw material market will decline next week.
Supply and demand side: Some manufacturers of nylon filament have high inventory, and there are plans to reduce the operating load of the equipment. There is a possibility of a decrease in on-site supply, and it is expected that the supply side of the nylon filament market will perform generally in the short term; Downstream domestic demand is limited, and there has been no significant improvement in foreign trade orders. Some downstream manufacturers have production reduction plans, and demand is expected to decrease. Therefore, it is expected that the driving force from the demand side of the nylon filament market will remain weak next week.
Overall, there are still downward expectations in the spot market for raw material caprolactam and the market for nylon PA6 chips, with weak cost support and no signs of improvement in downstream market demand. Industry players lack confidence in the future market, and Business Society analysis predicts that the price of nylon filament market will fall next week, with an expected decline of 100-300 yuan/ton.

The hydrofluoric acid market has been operating steadily this week. According to the analysis system of Shengyi Society, as of April 16th, the benchmark price of hydrofluoric acid in Shengyi Society was 12450 yuan/ton, an increase of 1.63% compared to the beginning of this month (12250 yuan/ton).
On the raw material side, the market for fluorite sulfuric acid, a raw material, is experiencing a weak decline, and the cost pressure on anhydrous hydrogen fluoride production enterprises has eased to some extent. According to the analysis system of Shengyi Society, as of April 16th, the benchmark price of Shengyi Society’s fluorite was 3731.25 yuan/ton, a decrease of -1.16% compared to the beginning of this month (3775.00 yuan/ton).
On the demand side: Downstream refrigerant domestic and foreign trade will usher in a peak demand season, with some enterprises producing at full capacity. Currently, market prices are still running at high levels, and the trading atmosphere is normal. Inventory pressure is gradually being released. The terminal sector has entered the peak production season, with increased demand supporting the continued high and firm price of anhydrous hydrogen fluoride.
Market forecast: In the near future, there will be a slight downward trend in the market price of raw material fluorite sulfuric acid. The cost pressure on anhydrous hydrogen fluoride production enterprises has eased, but it is expected that the decline in raw material prices will not be too large. The downstream refrigerant market is good, and the end demand has entered the production peak season. The demand side has certain support for the anhydrous hydrogen fluoride market. It is expected that the anhydrous hydrogen fluoride market will continue to operate at a high level in the future, and more attention should be paid to the news of leading enterprises and market supply and demand.

According to the Commodity Market Analysis System of Shengyi Society, the rise in the PP market in the first half of April was hindered, and the prices of most brand products fell back. As of April 16th, the mainstream offer price for wire drawing by domestic producers and traders is around 7565 yuan/ton, with an increase or decrease of+0.02% compared to the price level at the beginning of April.
price trend
In terms of raw materials:
In the first half of April, the US tariff policy was implemented, with tariff rates constantly changing and increasing to unprecedented heights. The tariff trade war launched by Trump has had a huge impact on the global economy. Crude oil, as a heavily affected area, has experienced a sharp drop in prices recently. At the same time, it seriously affects the domestic supply of propane, and also drags down the operation and profitability of PDH manufacturing enterprises. The highest strength in the propylene field is insufficient, and it has entered a weak oscillation trend. Overall, the prices of various raw materials in the first half of April did not provide strong support for the cost of PP.
Supply side:
In the first half of April, domestic PP enterprises had a large and stable load with small fluctuations, and the market supply remained generally abundant. Overall, the current industry load level is around 79%, with an average weekly production of approximately 760000 tons in China. Recently, Guangdong Petrochemical, CNOOC Shell, and Ningbo Jinfa have successively implemented maintenance plans, resulting in an overall expansion of production capacity losses and an expected supply contraction in the future. There is an upward trend in the supply side’s support for PP spot prices.
In terms of demand:
In the first half of April, the demand for PP remained stable with some weakness, and on-site trading maintained a weak rigid demand pattern. In terms of plastic weaving, the consumption level of terminal enterprises has generally stabilized. The demand for PP in fields such as architecture and agriculture is gradually increasing with the warming of temperatures. However, under the influence of international news such as equivalent tariffs imposed by the United States, the global economy has been greatly impacted and future uncertainty has increased. Although the domestic PP import and export dependence share is relatively small, its downstream product exports are hindered. Buyers tend to maintain production through scattered small orders in their purchasing operations, although there has not been a significant increase in new orders in the market. Overall, the demand side of PP weakened in the first half of April.
Future forecast
In the first half of April, the domestic PP market prices fluctuated weakly. From a fundamental perspective, the overall performance of upstream raw materials in supporting PP is average, with abundant industry supply and weak demand support in consumption. The future industry market pattern is characterized by a 1:2 bearish guidance formed by weak supply search and consumption, as well as weakened costs. There is a clear avoidance of suspicion within the market. In the short term, the price trend may not see a significant increase, and it is recommended to closely monitor the situation of tariffs and the circulation of goods.

After some factories raised their listing prices yesterday, Sinopec North China’s listing price increased by 100 to 6000 yuan/ton today, Yangzhou Shiyou’s listing price increased by 100 to 6000 yuan/ton, and Fuyu Petrochemical’s acetone price increased by 5900 yuan/ton. Based on the East China acetone market, the acetone market has slightly increased by 100 yuan/ton in the new week, with a price range of 5950-6000 yuan/ton.
The acetone offers in major mainstream markets across the country on April 15th are as follows:
Region/ Quotation/ Daily increase and decrease
East China region/ 5950-6000./ 50
Shandong region/ 6000./ 50
Yanshan region/ 6000./ 50
South China region/ 6100./ 50

The raw material pure benzene is operating strongly, with some cost support, reduced port inventory, and supply mentality support. However, the current terminal follow-up is average, and the sustained upward momentum is insufficient. In the short term, acetone is operating stably in multiple dimensions.

Last week (April 7-13, 2025), the adhesive short fiber market continued to be weak. According to the Commodity Market Analysis System of Shengyi Society, as of April 13, 2025, the average price of the adhesive short fiber market was 13480 yuan/ton, a decrease of 120 yuan/ton from the same period last week, with a weekly decline of 0.88%.
Last week (April 7-13, 2025), both the raw material main material dissolution slurry market and the auxiliary material liquid alkali market fell, while the sulfuric acid market remained stable, and the cost side market prices continued to decline; The overall supply of adhesive short fibers in the market decreased slightly during the week, and some manufacturers had high inventory levels, making it difficult to find favorable support from the supply side; The demand in the terminal market remains weak, and downstream yarn companies are experiencing sluggish shipments. Currently, the main consumption of raw material inventory is low, and the enthusiasm for replenishment is not good. The fatigue of the demand side remains unchanged. The price center of the upstream raw material market has fallen, and downstream yarn manufacturers are mostly adopting a wait-and-see attitude. The support on both the cost and demand sides is weak, coupled with the continuous accumulation of inventory in the adhesive short fiber market. Some manufacturers are selling at lower prices, and the supply of low-priced goods in the market has increased, resulting in a weak decline in the price of adhesive short fiber market.
In terms of cost: Last week (April 7-13, 2025), the market price of raw material dissolution slurry continued to decline, the market price of auxiliary material liquid alkali narrowly declined, the market price of sulfuric acid remained stable, and the market price of raw materials significantly decreased. The average production cost of adhesive short fibers also decreased.
Supply and demand: Last week, the operating rate of the adhesive short fiber industry remained at around 81.47%, with a decrease in production compared to last week. During the week, some units of the adhesive short fiber factory underwent load reduction maintenance, resulting in a decline in overall supply in the industry. The speed of on-site shipments is gradually slowing down, and the inventory levels of various manufacturers are showing an increasing trend. The inventory level of the adhesive short fiber industry is improving. The inventory of finished products in the downstream cotton yarn market has increased, and prices have entered a downward channel. Downstream yarn market transactions are not ideal, and some yarn factories have reduced their operating loads, resulting in a decrease in demand for adhesive short fibers. During the week, they maintained a high level of replenishment for essential needs, but the demand side did not improve.
Market forecast:
On the raw material side, the main material dissolution slurry market and the auxiliary material sulfuric acid market are mainly consolidated, and there is still a possibility of a decline in the liquid alkali market. Therefore, it is expected that the market price of adhesive short fiber raw materials will continue to be weak this week, and the cost side support will be insufficient.
Supply and demand side: Due to the impact of high inventory, some adhesive short fiber manufacturers may continue to reduce their equipment load, so it is expected that the supply of adhesive short fiber market will decrease in the short term; The downstream market is experiencing sluggish shipments, leading to a slowing down trend in the delivery speed of adhesive short fibers. As a result, there is less demand for replenishment, so it is expected that there will be little positive support for the demand side of the adhesive short fiber market this week.
Overall, the main raw material dissolution pulp market may be weakly consolidated, with some adhesive short fiber manufacturers having high inventory and downstream yarn factories mainly consuming raw material inventory. With mixed news on the market, Business Society analysis predicts that the domestic adhesive short fiber market will mainly consolidate slightly in the short term, with prices expected to be between 13300-13500 yuan/ton.
