Zhong Guo Fa Zhan Wang·2025-10-22 08:15Core Viewpoint - The successful application of domestically produced fluoropolymer-based composite additives in the production of long-chain branched metallocene polyethylene resin by Daqing Petrochemical has significantly reduced production costs and enhanced the self-sufficiency of the polyethylene industry supply chain [5]. Group 1: Domestic Production and Cost Reduction - Daqing Petrochemical has achieved full domestic production of 15 commonly used composite additives for polyethylene resin, which has notably lowered production costs [5]. - The company’s polyethylene production capacity is approximately 1.2 million tons annually, requiring nearly 10,000 tons of chemical "three agents" each year [5]. Group 2: Technological Advancements - The successful application of the domestic fluoropolymer-based composite additives is a result of extensive efforts by Daqing Petrochemical's technical team, which involved multiple rounds of research and development [5]. - The production process was optimized by establishing detailed production plans based on the characteristics of the domestic additives, including key parameters such as temperature and pressure [5]. Group 3: Training and Monitoring - Specialized training was provided to operational staff to ensure effective use of the new additives, with technical experts monitoring the production process to dynamically optimize parameters [5]. - The final product quality achieved stability and performance comparable to that of imported additives, demonstrating the effectiveness of the domestic alternatives [5].
