Petrochemical Research Institute of CNPC and Shandong Yulong Petrochemical Co. Ltd. formally signed the "Technical License Contract for TBIR and Integrated Rubber."

TBIR is a copolymer rubber of butadiene and isoprene. It is a synthetic rubber that has not yet been industrialized in China. It will be widely used in high-performance tires, low-temperature components and sealing materials required by the military industry, and broad industrial application prospects.

Integrated rubber is the third-generation SSBR. It combines the advantages of NR, BR, and SBR.

The two technologies approved have reached the advanced international level. Both products are urgently needed in the domestic market and have great significance for enhancing China's synthetic industry. Among them, TBIR is the world's first completed set of technology for industrialization.
