Project Name: Preparation and Application of High-performance Green Tire Synthetic Rubber－50000 tons/year’s full set of rare earth butadiene rubber industrialization technology

Project Owner: Changchun Institute of Applied Chemistry (CIAC) Chinese Academy of Sciences

Project Profile: High-performance green tire has the advantages of better  environmental protection, lower energy consumption and super-safety degree, etc, which meet the requirements in Eu−labeling law, such as fuel-efficient, wet resistance and wear resistance. Compared with the traditional tire, high-performance green tire’s rolling resistance can be reduced by 22%~35%, and automobile fuel consumption by 3%~8%. Rare earth butadiene rubber green tires will be the mainstream products on the tire market. Changchun Institute of Applied Chemistry Chinese Academy of Sciences has pioneered the development of rare earth butadiene rubber in the world and has a breakthrough on the core technology of rare-earth metal catalyzed coordination polymerization, preparing high performance green butadiene rubber with high cis content, perfect linear chain structure and ultra-low glass transition temperature.The combination of solution-polymerized styrene-butadiene rubber and and high performance green butadiene rubber will endow our tires with good flexing resistance, low rolling resistance and high abrasion resistance, which could effectively regulate the "magic triangle" performance. At present high efficiency, stable and low cost homogeneous rare earth catalyst preparation technology with independent intellectual property rights has been developed, as well as 10000-ton butadiene rubber preparation technology. The technologies of whole set of apparatus have characteristics of safety and environmental protection, preparing the tires with the Eu-double B level in fuel consumption and wet resistance. Project investment is expected to RMB 200 million Yuan.
