In 2025, the total production of caprolactam, the upstream raw material for nylon filament, is projected to reach 6.85 million tons, representing a year-on-year increase of only 5.38%. This growth rate is significantly lower than the expansion of production capacity, primarily due to frequent planned and unplanned maintenance shutdowns throughout the year, which have prevented the effective release of some capacity and limited production growth. PriceSeek’s analysis of caprolactam assigns a bullish-bearish score of 1. The article notes that caprolactam production in 2025 is expected to increase by only 5.38%, a growth rate significantly lower than capacity expansion, mainly due to frequent planned and unplanned maintenance shutdowns leading to insufficient capacity release. Supply constraints will reduce spot market availability, potentially driving up spot prices against a backdrop of stable demand, which is considered a moderate positive factor.

Nylon POY, with a bullish-bearish score of 1, is a downstream product of nylon filament. Its production costs are affected by the constrained supply of upstream caprolactam. Rising raw material costs may be passed on to the production side, pushing up spot prices. In the absence of significant changes in demand, this is considered a moderate positive factor.

Nylon FDY, with a bullish-bearish score of 1, faces raw material supply tightness due to limited growth in upstream caprolactam production. As a derivative product, its production costs will increase. Supply-side pressures may elevate spot prices, which is considered a moderate positive factor in a stable demand environment.

Nylon DTY, with a bullish-bearish score of 1, will experience higher raw material costs due to insufficient caprolactam supply. Capacity bottlenecks caused by maintenance shutdowns may reduce spot availability. Cost-driven factors are favorable for spot prices under steady demand conditions, making this a moderate positive factor.
