On June 4, Guangxi Petrochemical Company successfully completed the industrial trial production of SSBR2055DF2—a high-end grade of chain-end functionalized solution-polymerized styrene-butadiene rubber (SSBR)—achieving stable, full-load operation for the first time. This milestone marks a historic breakthrough for the company in the field of high-performance synthetic rubber.
Chain-end functionalized SSBR is a core material for high-performance green tire treads; it reduces rolling resistance while enhancing wet-grip and wear-resistance properties. The market for such products has long been dominated by foreign enterprises. This successful achievement of mass production fills a gap in Guangxi Petrochemical’s high-end rubber production portfolio.
After six months of intensive technical development, the company’s technical team successfully transitioned from initial trial production to full-load mass production. By leveraging customer feedback, they precisely optimized the product's molecular structure to meet the specific processing requirements of downstream manufacturers. They also overcame technical challenges and completed systematic upgrades to key equipment, laying a solid foundation for subsequent large-scale industrial production. Currently, Guangxi Petrochemical’s SSBR unit is fully capable of producing chain-end functionalized rubber at maximum capacity, and the SSBR2055DF2 grade is steadily entering the supply chain evaluation systems of leading domestic tire manufacturers.
