Nylon Chain Expansion: Hengyi Petrochemical's $670M Bet on Melt Direct Spinning

Amid industry-wide pressure, Hengyi Petrochemical is bucking the trend by investing 4.87 billion yuan in a 400,000-ton PA6 melt direct spinning project. This move reflects a renewed focus on cost and low-carbon advantages, as traditional chip spinning profit margins shrink and integrated layouts become key for leading players.

Background

Through subsidiaries Guangxi Hengyi New Materials and Hangzhou Yizhijin New Materials, Hengyi will build the project in Guangxi New Materials Industrial Park and Yizhijin New Materials Industrial Park, with an 18-month construction period funded by internal and external capital. Notably, Guangxi Hengyi's existing 600,000-ton PA6 chip facility will run at full capacity through 2026, and the new 400,000-ton capacity extends the company's business downstream to spinning, completing its nylon chain.

Technically, melt direct spinning isn't new, but Hengyi's self-developed process stands out: water use drops 80%, electricity 30%, and intermediate steps like packaging, warehousing, and transport are eliminated. This cuts costs and emissions, aligning with the industry's green transition. For buyers, it means more consistent quality and faster delivery, as fewer steps improve product uniformity and supply chain responsiveness.

Industry Impact

Hengyi's move essentially converts cost advantages into supply chain influence. With scale in PA6 chips, the company now adds value through spinning, directly serving weaving and apparel customers. This integrated model, proven in polyester, may trigger follow-the-leader moves in nylon. The dual-base strategy in Guangxi and Hangzhou offers distinct benefits: Guangxi proximity to raw materials and Southeast Asia cuts logistics costs; Hangzhou closeness to fabric and garment clusters enables quick response. For traders, increased PA6 filament supply could widen price negotiation room.

However, 400,000 tons of new capacity raises oversupply concerns if others expand. Yet Hengyi's cost edge—lower water, power, and logistics per ton—allows profitability even in price wars. This pressures smaller chip spinners, accelerating industry consolidation.

Practical Advice

For Buyers - Track progress of Hengyi's Guangxi and Hangzhou bases to secure long-term contracts and cost benefits. - Compare quality consistency of melt direct spun products against traditional spun, optimizing your fabric development. - Leverage supplier integration for joint R&D to reduce trial costs.

For Trading Firms - Monitor export strategies of Hengyi's new capacity, especially Southeast Asia, to adjust sourcing. - Use suppliers' green processes as a premium point in negotiations with overseas clients. - Diversify suppliers to avoid over-reliance and watch chip spinners' transitions to mitigate risks.
