On May 10th, the reporter learned that 20 products were selected in the list of "Innovative Products of New Chemical Materials in 2023" issued by China Petroleum and Chemical Industry Federation. Among them, the functionalized solution polymerized styrene-butadiene rubber SSBR72612F developed by Dushanzi Petrochemical Company is on the list.

Functionalized solution polymerized styrene-butadiene rubber SSBR72612F products are groundbreaking in the industry. During the research and development of this product, the company solved a series of problems such as the amplification preparation of functionalized initiator, and conquered the industrial production technology of functionalized solution polymerized styrene-butadiene rubber, forming a 30,000-ton/year industrial production demonstration of functionalized solution polymerized styrene-butadiene rubber. This product is the first functionalized solution polymerized styrene-butadiene rubber product independently researched and developed in China and realized stable industrial production. It was selected into the Product Manual of Scientific and Technological Innovation Achievements of Central Enterprises (2022 Edition) issued by the State-owned Assets Supervision and Administration Commission of the State Council.

Functionalized solution polymerized styrene-butadiene rubber SSBR72612F is an ideal material for high-performance green tires, which has the advantages of wet skid resistance, low rolling resistance and wear resistance. Its successful research indicates that China has conquered the core technology of high-performance tire tread rubber and helped domestic tire rubber to realize technical lane-changing overtaking.

The tire made of this product has been tested by professional institutions in the European Union, and the rolling resistance coefficient reaches Grade A and the wet skid resistance index reaches Grade B, which indicates that the industrialization of China Petroleum's functionalized solution polymerized styrene-butadiene rubber in the field of high-performance tires has reached the international advanced level.
