重塑产业链格局 吉林石化让国产乙丙橡胶迈进高端市场

Core Viewpoint - Jilin Petrochemical has successfully developed a domestic catalyst for ethylene-propylene rubber, breaking the reliance on imported catalysts and entering high-end markets, marking a significant step towards becoming a leader in the industry [1][2][6]. Group 1: Market Opportunities and Strategic Layout - In recent years, Jilin Petrochemical has seen steady growth in production and market share as the only domestic company capable of producing both binary and ternary ethylene-propylene rubber [2]. - The company identified its over-reliance on imported catalysts as a major limitation to its high-quality development and initiated a project to develop domestic catalysts in collaboration with research institutions [2][3]. Group 2: From Laboratory to Production Line - The project to develop a domestic catalyst involved extensive collaboration with Qingdao University of Science and Technology, leading to the successful identification of a catalyst suitable for industrial trials [3]. - Over three years, the team addressed 56 key issues related to the catalyst's performance and developed 102 risk mitigation measures, culminating in a viable industrial production trial plan [3]. Group 3: Breakthroughs in Production - On April 19, 2024, the new domestic vanadium catalyst was successfully tested in industrial production, yielding over 50 tons of qualified product, making Jilin Petrochemical the first company in China to produce ternary ethylene-propylene rubber using a domestic catalyst [4]. - A second industrial trial in February 2025 further improved product quality, demonstrating the effectiveness of the new catalyst [4]. Group 4: Market Penetration - Following the successful trials, Jilin Petrochemical engaged with eight leading manufacturers in the automotive sealing and sponge strip sectors to promote its new products [5]. - After thorough demonstrations and trials, a leading automotive sealing manufacturer agreed to purchase Jilin Petrochemical's J-6095 product, highlighting the shift in market dynamics previously dominated by foreign products [5]. Group 5: Industry Impact - The successful conversion of the domestic catalyst research results not only reshapes the ethylene-propylene rubber industry chain but also reflects the strong confidence and capability of state-owned enterprises in achieving technological self-reliance [6].
