The National Science and Technology Support Project “Isoprene rubber production technology development†jointly undertaken by the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences and the China Petroleum Jilin Petrochemical Branch Research Institute has made important progress recently. The rare earth isoprene rubber pilot product has been successfully applied to all steel trucks. Meridian tires can replace natural rubber by 40%. Tested and evaluated by the China Rubber Industry Association Material Testing and Research Center, the molding, processing and performance of tires are not affected. At present, Jilin Petrochemical Company is building a 1,000-ton isoprene rubber production plant, which will be delivered and accepted in the first half of 2011. Isoprene rubber, also known as "synthetic natural rubber", is the best substitute for natural rubber due to its structure is closest to natural rubber. It can be widely used in tires, tapes, rubber hoses and other rubber applications. It is the seven basic types of synthetic rubber. The only type of rubber that could not be industrialized in China. The realization of industrialization of isoprene rubber as soon as possible can not only solve the problem of insufficient natural rubber resources in China, but also promote the comprehensive utilization of carbon five fractions. Changchun Yinghua Institute of the Chinese Academy of Sciences and PetroChina Jilin Petrochemical Company developed the production technology of isoprene rubber under the support of the “Technology Development of Isoprene Rubber Production†of the National Science and Technology Support Program. He has made important breakthroughs in catalysts, polymerization and agglomeration processes, control of cis-isomer content, molecular weight and distribution of isoprene rubber, and was the first to have independent intellectual property rights, high molecular weight, narrow molecular weight distribution and high cis-1,4 structure content in China. The new rare earth isoprene rubber, and carried out a large number of tests on a 20-liter continuous polymerization molding test device, developed a pilot product, and successfully applied to all-steel radial tires.
