Xuyang Group hexamethylene diamine project put into production: a key breakthrough in the autonomy of China's nylon industry chain

Technological breakthrough to break the international monopoly pattern

on December 3, China Xuyang Group announced that its Yuncheng Park high-end polyamide new materials project is about to be put into production. The project uses Xuyang's self-developed caprolactam to directly prepare hexamethylene diamine innovative process, marking China's achievement in the field of high-performance nylon raw materials. Major technological breakthroughs.

Hexanediamine is the core monomer raw material for the production of nylon 66(PA66), and its production technology has been monopolized by international chemical giants for a long time. Xuyang Group has set up a research and development team of nearly 100 people, and has successfully developed the "technology of direct production of hexanediamine from caprolactam" for eight years, skipping the intermediate link of adiponitrile in the traditional process and forming a full set of independent intellectual property rights. This innovative process not only simplifies the production process, but also achieves significant optimization in terms of investment cost, operation complexity and raw material conversion rate, laying the foundation for the independent control of China's nylon industry chain.

The first phase of the project has a production capacity of 50000 tons/year of hexamethylene diamine. After production, it will open up the complete industrial chain of "caprolactam-hexamethylene diamine-PA66" and form a vertical integrated layout. This means that Xuyang will transform from a single raw material supplier to a high-end new material solution provider, and the added value of the industrial chain will be qualitatively improved.

Capacity Advantage and Market Impact

xuyang Group currently has a caprolactam production capacity of 750000 tons/year, with a domestic market share of about 7.1. Its production capacity is distributed in Cangzhou Park (450000 tons/year) and Dongmingyuan District (300000 tons/year). The caprolactam project in Cangzhou Park started in 2015, the first phase of 100000 tons was put into production in October 2015, and the capacity was expanded to 150000 tons/year in June 2019, supporting the construction of 150000 tons/year caprolactam, 135000 tons/year cyclohexanone and power generation equipment; the second phase of the 300000-ton project achieved a cost reduction of 1950 yuan/ton through technical optimization, building a strong cost competitive advantage.

The commissioning of hexamethylene diamine project will form a high degree of synergy with the existing caprolactam industry chain: first, the internal supply of raw materials will greatly reduce procurement costs and supply chain risks; Secondly, sharing public works and logistics facilities will further dilute unit costs. Third, the complete industrial chain layout will significantly enhance Xuyang's pricing power and bargaining power in the nylon market.

Based on the project, Xuyang clearly put forward the strategic goal of building a million-ton nylon 66 + special nylon industrial cluster, and accelerate the research and development and market expansion of high-end products such as elastomer nylon and high-temperature nylon, and strive to cultivate caprolactam into a "national first, global leading" chemical product line.

Impact on global supply chains

for practitioners in the international chemical industry chain, this project has multiple strategic implications:

supply pattern reconstruction: The increase in China's hexamethylene diamine production capacity will change the global supply pattern, especially the raw material supply in the Asia-Pacific region will be more diversified, creating competitive pressure on traditional suppliers.

price system adjustment: The acceleration of the localization process may promote the reconstruction of the price system of hexamethylene diamine and downstream PA66, and it is recommended that overseas traders pay attention to the conduction effect of the price trend of the Chinese market on the international market.

supply chain security as the world's largest nylon consumer market, China's independent production of hexamethylene diamine will reduce its dependence on imports and the global supply chain will be more balanced.

It is recommended that international industrial chain enterprises pay close attention to the rhythm of Xuyang's subsequent production capacity release, export strategy and pricing policy, timely assess the impact on their own supply chain layout and procurement strategy, and look for new cooperation opportunities under the trend of rapid development of China's nylon industry chain.
