Core Viewpoint - The successful commissioning of the 120,000 tons/year hexamethylenediamine unit at Shanghai Jieda Nylon Materials Co., Ltd. marks a significant milestone in establishing a comprehensive nylon integration industrial base in Shanghai Chemical Industry Park, centered around Invista's 400,000 tons/year adiponitrile capacity [2][3]. Group 1: Project Overview - The Shanghai Jieda Nylon integration project includes a production capacity of 120,000 tons/year of hexamethylenediamine, 120,000 tons/year of Nylon 66, and additional capacities for Nylon 610/612 resin slices and modified resin slices [4]. - The total investment for the project is 1.5 billion yuan, with an expected annual sales revenue of 4.5 billion yuan [4]. Group 2: Technology and Partnerships - The hexamethylenediamine unit utilizes an optimized and upgraded low-pressure hydrogenation process for adiponitrile, recognized as the most advanced in China [5]. - The Nylon 66 polymerization unit employs Invista's proprietary Nylon 66 polymerization technology, which is considered the most advanced internationally [6]. - In mid-2023, Shanghai Jieda signed a tripartite cooperation agreement for the technology licensing of the 120,000 tons/year hexamethylenediamine project with Henan Pingmei Shenma Nylon Engineering Technology Co., Ltd. and Hualu Engineering Technology Co., Ltd. [5]. Group 3: Future Developments - A groundbreaking ceremony for the second phase of the nylon integration project was held on January 9, 2023, with plans for a third phase to develop high-temperature nylon and civilian spinning nylon polymerization capacity, along with corresponding engineering plastic capacity [7].
