【Frontiers in HaiChuan Chemical Technology】New breakthrough achieved with domestically produced vanadium catalysts for EPDM

Thread Content

New breakthrough achieved with domestic new vanadium catalyst for EPDM production. On February 26, Jilin Petrochemical Company reported that its organic synthesis plant successfully completed the second industrial-scale test of this new domestic vanadium catalyst at Line C1 of the EPDM production facility. After 87 hours of stable operation of the test, the ENB content in the product reached the target set for this research, achieving a new breakthrough in the quality of the new vanadium grade J-6095. This new breakthrough also marks Jilin Petrochemical’s Organic Synthesis Plant as the only enterprise in China to produce EPDM products suitable for high-value applications using domestically manufactured catalysts. The J-6095 EPDM produced here can be used in areas such as automotive foam strips, automotive hoses, and molded foam products, and business partnerships have already been established with leading companies in these fields. The third monomer in EPDM is ENB, whose full name is ethylenic norbornene. EPDM with a high content of ENB exhibits fast vulcanization rates, excellent tensile strength and tear resistance, as well as low compressive set in rubber products. Until then, domestic manufacturers of EPDM had been unable to produce products with a high ENB content on par with imported ones. During the second industrialization test, Jilin Petrochemical Company made full use of the experience gained from the first industrialization test in April 2024. By setting benchmarks against advanced standards, assembling a capable team, and overcoming the various uncertainties associated with the research and development of the new vanadium catalyst, it scientifically adjusted the polymerization formulas and finely optimized the process parameters, ensuring safe and stable operation throughout the entire industrialization test process.
