On February 14th, it was reported that Xinhecheng's 10-billion-yuan nylon industrial chain project in the Nangang Industrial Zone has obtained construction permits. The first phase of the project plans to produce 100,000 tons/year of adiponitrile, 100,000 tons/year of hexamethylenediamine, and 140,000 tons/year of nylon 66. The second phase plans to produce 400,000 tons/year of nylon 66, with the first phase expected to commence production in 2027. Chempricehub analysis: - **Adiponitrile**: Bull-bear score: -1 Xinhecheng plans to produce 100,000 tons/year of adiponitrile, with production expected to start in 2027. The additional capacity will increase market supply, potentially easing supply-demand dynamics and exerting downward pressure on spot prices. - **Hexamethylenediamine**: Bull-bear score: -1 The first phase of the project plans to produce 100,000 tons/year of hexamethylenediamine. The expansion of production capacity will boost market supply, and with the 2027 production timeline, it may limit the upward potential of spot prices, resulting in a clear bearish impact. - **Nylon 66**: Bull-bear score: -1 The first phase will add 140,000 tons/year of nylon 66 capacity, and the second phase will add 400,000 tons/year, with a total investment of 10 billion yuan. The substantial increase in supply will intensify market competition, likely suppressing spot prices in the long term and creating a neutral-to-bearish market outlook.
