On January 2, 2025, the new materials project, for which Zhongzhe Group invested a total of 3 billion yuan, officially commenced construction in the Lingang New Materials Industrial Park in Xiapu Sub-district, Beilun District, Ningbo. The high-end new materials project of Zhongzhe Group has a total investment of 3 billion yuan and an annual production capacity of 200,000 tons; it is the first project of Zhongzhe Group that integrates production with trade. The solpolybutadiene rubber (SSBR) and low-cis butadiene rubber (LCBR) produced by this project will meet the demands of new energy vehicles for green, high-performance tires. They will not only enable domestic substitution but also fill the gap in green, high-performance tire materials in Zhejiang Province. It is reported that solution-polymerized styrene-butadiene rubber is an important raw material for the production of green, high-performance tires. It is synthesized using butadiene and styrene as polymerization monomers, and the polymerization processes mainly include batch polymerization and continuous polymerization. In the past, China relied mainly on imports from countries such as Japan and South Korea; the annual volume of imports was around 400,000 tons, with a transaction value of nearly 7 billion yuan. As of the end of December 2023, there were 7 enterprises in China producing SSBR, with a total production capacity of 437,000 tons per year. However, the amount of high-end products such as functionalized SSBR remains low, and this is not sufficient to meet the demands of industries such as high-end tires. LCBR stands for low cis-1,4-polybutadiene rubber, and its main use is as a toughening agent for continuous bulk ABS and HIPS. At the construction site, Zhongzhe Group also signed a cooperation agreement with the \"Academician Team Innovation Center for High-Performance Synthetic Materials\" at Beijing University of Chemical Technology.
