The raw material market continues to rise in price
In terms of cost: Last week (June 16-22, 2025), the spot market price of caprolactam was relatively strong, and the weekly settlement price of Sinopec’s high-end caprolactam was raised to 9650 yuan/ton, an increase of 425 yuan/ton from the previous period. The market trend of nylon PA6 chips is gradually stabilizing, with strong cost support. As of June 22, 2025, the benchmark price of caprolactam in Shengyi Society was 9550 yuan/ton, and the price continued to rise, with a weekly increase of 2.41%. During the week, the market price of high-speed spun nylon PA6 slices slightly increased, with a 2.19% weekly increase in nylon PA6 prices, 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 nylon filament market will fluctuate and consolidate in the short term, with stable prices as the main factor.
