New Type Rubber to be Industrialized Soon

After years of extensive and continuous research, the Changchun Institute of Applied Chemistry, CAS has made great progress on rare earth-based catalyst system for isoprene polymerization, which possesses characteristics of highly active, highly cis-1,4 oriented, low cost and controllable molecular weight and molecular weight distribution. Thereafter, with catalyst technology as the core, the advanced engineering and technologies on polymerization, coagulation and drying processes have been developed and assembled in Mar, 2011, symbolizing complete sets of industrial technology with Chinese intellectual property rights on NdIR production has been successfully developed. With complete sets of industrial technology from CIAC, the Shandong Shenchi Petrochem, Co. Ltd. has built 30kt/a rare-earth catalyzed isoprene production facility, and the production line ran successfully on Sep. 13, 2012, with only one trial, establishing a new record among the industrial synthetic rubber facilities of the same size. So far, the facility has been operating smoothly with stable quality and optimal processing conditions. It is learned that Shenchi is planning to build new facilities based on the same technology from CIAC, but to increase the capacity of NdIR to 100kt/a in three years.
