HONG KONG, May 4, 2026 – (ACN Newswire) –At 6:18 a.m. on May 4, 2026, with the effective conclusion of the last production procedure, China Risun Group’s 50,000-ton/ year caprolactam-to-hexamethylenediamine (HMDA) plant at the Yuncheng Production Base was completely incorporated, accomplishing a one-time effective start-up and producing certified items. By straight producing HMDA from caprolactam, China Risun has actually broken the enduring foreign monopoly on adiponitrile innovation (adiponitrile is the essential basic material for HMDA, the intermediate for nylon 66, and is considered as the “throat” of the nylon market chain). This advancement in “chokepoint” innovation lays the structure for China Risun’s tactical implementation in high-end brand-new products, slowly constructing a million-ton-scale “nylon 6 + nylon 66 + specialized nylon” commercial cluster, and developing a national-level nylon brand-new products base.
Market Background and Current Development
HMDA is a vital basic material supporting the updating of the nylon brand-new products market. Development and advancements in its production innovation are of terrific significance to the advancement of China’s chemical market. Presently, the market depends on the butadiene-based procedure to produce adiponitrile and after that HMDA. Fully grown, this path has significant imperfections: on one hand, production expenses stay high due to changes in butadiene feedstock costs; on the other hand, the procedure is complicated, with very high technical barriers, and crucial patents have actually long been monopolized by abroad business.
Versus this background, China Risun Group originated an independent R&D course, establishing a brand-new innovation and procedure to straight produce HMDA from caprolactam. This development breaks market monopolies, gets rid of crucial technical barriers, and opens a brand-new path for HMDA production.
China Risun’s R&D Journey and Innovation Achievements
As the world’s biggest independent coke manufacturer and provider, and a worldwide leader in distinguished coal chemical operations, China Risun Group has actually carefully lined up with nationwide tactical requirements and properly comprehended commercial improvement patterns. As early as 2011, the business visualized the capacity of the caprolactam market, broadening its scale while developing R&D groups to perform independent research study on brand-new procedures and innovations for caprolactam and downstream markets.
Over more than a years, China Risun’s R&D group performed over a thousand laboratory-scale experiments, gradually advancing to pilot-scale building and construction and steady operation, and eventually attaining complete commercial application. Throughout the journey from lab-scale to pilot-scale, procedure advancement, and industrialization, the group took on over a hundred research study subjects, protected lots of core patents with totally independent copyright rights, and effectively established the ingenious procedure path of straight producing HMDA from caprolactam.
Provided the disruptive, pioneering, and tactical worth of this accomplishment, Shandong Province has actually designated China Risun Group’s task as a provincial crucial engineering effort.
China Risun’s Core Industrial Advantages and Competitiveness
The commissioning of the HMDA task highlights China Risun’s strengths in commercial synergy and R&D development, considerably boosting its core competitiveness in nylon brand-new products and combining its management position in the chemical market.
1. Steady and Efficient Industrial Synergy
The steady operation and full-blown production of the HMDA plant will synergize with the Group’s existing 810,000-ton/ year caprolactam market chain and upstream assembly line at Yuncheng Industrial Park, consisting of adipic acid, cyclohexanone, and nitric acid. This combination allows resource complementarity, technological updating, capability growth, and made the most of effectiveness.
China Risun Group has a strong structure in the aromatics market chain, extending from benzene to caprolactam to HMDA, and even more downstream into high-end markets such as polymer chips, fiber spinning, weaving, injection molding, adjustment, and polyurethane. This speeds up the building of a complete nylon 6 + nylon 66 + specialized nylon market chain covering “upstream basic materials– midstream monomers– downstream items.”
2. Constant R&D and Innovation Capacity
Compared to conventional procedures, the caprolactam-to-HMDA innovation provides clear benefits: streamlined procedure circulation, lower financial investment expenses, greater security, and enhanced basic material conversion rates.
Both the procedure and driver are safeguarded by China Risun’s independent copyright rights, breaking through domestic and global technical barriers in polyamide basic materials and filling a vital space in China.
3. Continuous Process Optimization and Cost Reduction
China Risun’s caprolactam-to-HMDA innovation attains substantially lower system production expenses compared to the butadiene path. Future combination of R&D and production will even more minimize running expenses.
As the world’s second-largest caprolactam manufacturer, China Risun’s scale benefits, market chain combination, and thorough supporting facilities make its HMDA items extremely cost-competitive.
Future Planning and Development Strategy
Around the caprolactam market chain, China Risun Group has actually currently established and booked numerous innovations and items, consisting of HMDA and flexible nylon. With the constant stabilization and updating of its core innovations, China Risun will broaden its scale and inject brand-new momentum into China’s nylon 66 and associated markets.
Looking ahead, China Risun Group will stay dedicated to innovation-driven advancement and service-oriented development, deepening its vertically incorporated design, tactically cultivating high-end chemicals and brand-new products, and methodically enhancing its brand-new products portfolio. The business is committed to assisting China even more get rid of chemical and brand-new products innovation barriers, developing an up-to-date, self-governing, and manageable commercial system, and attaining domestic replacement of essential products such as nylon 66– contributing China Risun’s strength to the country.
