PriceSeek Analysis on Caprolactam
Bull-Bear Score: -2
The article indicates that caprolactam capacity reached 8.18 million tons in 2025, a year-on-year increase of 13.30%, with growth rates exceeding 10% in most years from 2021 to 2025. The continuous expansion of capacity significantly increases the risk of oversupply, potentially leading to downward pressure on spot prices, which constitutes a major bearish factor for the market.

Nylon DTY
Bull-Bear Score: 1
As an upstream raw material for nylon filament, the growth in caprolactam capacity may reduce raw material costs. The production cost of nylon DTY is expected to decrease, thereby providing positive support for spot prices and benefiting producers' profit margins. The score indicates a generally positive impact.

Nylon POY
Bull-Bear Score: 1
The rapid expansion of upstream caprolactam capacity and increased supply may lower raw material prices. The reduction in nylon POY production costs helps stabilize or enhance the competitiveness of spot prices, forming a generally positive influence on the market.

Nylon FDY
Bull-Bear Score: 1
The 13.30% growth in caprolactam capacity will reduce the raw material costs for nylon FDY, potentially alleviating production pressure and supporting the stability of spot prices. This factor constitutes a generally positive impact on the nylon FDY market.
