年产5000吨长碳链尼龙项目公示

Group 1 - The article discusses the environmental impact report acceptance for Zhejiang Juwei High Polymer Materials Co., Ltd.'s production base for long-chain polyamide and modified products, with a total investment of 310.6 million yuan and an environmental investment of approximately 4.2 million yuan [2] - The first phase of production will yield 2500 tons per annum (t/a) of long-chain polyamide, with a second phase planned to add another 2500 t/a, resulting in a total capacity of 5000 t/a, of which 2400 t/a will be used for modified products [2] - The final sales scale for long-chain polyamide will be 2600 t/a, while the modified products will have a sales scale of 3000 t/a after the second phase implementation [2] Group 2 - Long-chain polyamides, represented by PA612 and PA1012, are characterized by low moisture absorption and high toughness, making them suitable for applications in key components such as cooling pipes for new energy vehicles, hydrogen storage bottle liners, and air suspension pipes [3] - The production breakdown includes 1250 t/a each for PA612 and PA1012 in the first phase, with a total of 2400 t/a allocated for modified products, leading to a combined output of 8000 t/a in the second phase [4]
