my country’s styrene-butadiene rubber industry structure continues to optimize, and the industry’s high-end development trend appears

Styrene-butadiene rubber (SBR), polystyrene-styrene-butadiene rubber copolymer, is a copolymer elastomer with styrene and styrene-butadiene rubber as the main monomers. Styrene-butadiene rubber is a type of synthetic rubber, and it is also the variety with the highest output and largest consumption among synthetic rubbers. Styrene-butadiene rubber has good comprehensive properties and is mainly used in the production of tires, auto parts, footwear, hoses and other rubber products. Its application fields are very wide.

According to different polymerization processes, styrene-butadiene rubber can be divided into two categories: emulsion-polymerized styrene-butadiene rubber (ESBR) and solution-polymerized styrene-butadiene rubber (SSBR). Solution-polymerized styrene-butadiene rubber has better performance and is used in high-performance tires. Widely, in 2020, my country’s solution polymerized styrene-butadiene rubber production capacity was about 330,000 tons, and the main production enterprises were Shandong Huamao, Dushanzi Petrochemical, and Liaoning Northern Dynasol; the production capacity of latex polystyrene-butadiene rubber was overcapacity. In 2020, my country’s latex polystyrene-butadiene rubber production capacity was overcapacity. The production capacity of polystyrene-butadiene rubber reaches 1.42 million tons, but the actual output is less than 950,000 tons. Overall, the structure of my country’s styrene-butadiene rubber industry is constantly being optimized, and the proportion of high-end styrene-butadiene rubber production capacity is gradually increasing.

According to the “2022-2026 China Styrene Butadiene Rubber Industry Brand Market Structure and Competitors Field Investigation Report released by the Industrial Research Center , at this stage, the global styrene-butadiene rubber market as a whole is in an oversupply situation. Global styrene-butadiene rubber production capacity is mainly concentrated in Northeast Asia and North America, with the combined production capacity of these two regions accounting for 60%. Under the trend of global industry shifting eastward, the focus of styrene-butadiene rubber production capacity has gradually shifted to Northeast Asia. From 2010 to 2020, the proportion of styrene-butadiene rubber production capacity in Northeast Asia increased from 40% to about 43%, while the proportion of production capacity in North America increased from 40% to about 43%. 22% dropped to about 17%.

The production capacity of styrene-butadiene rubber is highly concentrated. Specifically, PetroChina and Sinopec are the main suppliers of emulsion-polymerized styrene-butadiene rubber in the world. In terms of solution-polymerized styrene-butadiene rubber, Asahi Kasei, Shengxi Oju, and Prism are the world’s major suppliers. supplier. my country is a major producer of styrene-butadiene rubber. In 2020, there will be 20 major styrene-butadiene rubber manufacturers in my country. Domestic styrene-butadiene rubber is mainly emulsion polystyrene-butadiene rubber. my country’s styrene-butadiene rubber production capacity is relatively concentrated, with the combined production capacity of East China, North China and Northeast China accounting for 78%. At present, the supply of styrene-butadiene rubber in my country is sufficient, and the new production capacity of the industry will be limited in the future. With the upgrade of market consumption and the advancement of process technology, the styrene-butadiene rubber industry will continue to upgrade to high-end, environmentally friendly, and high-performance aspects.

Industry analysts said that as the synthetic rubber type with the highest output and largest consumption in the world, styrene-butadiene rubber has excellent comprehensive properties and its application It covers a wide range of fields. Currently, the global styrene-butadiene rubber market is oversupplied, and new production capacity in the industry will be limited in the future. my country is a major producer of styrene-butadiene rubber, but its products are mainly concentrated in the middle and low-end fields. The market share of solution-polymerized styrene-butadiene rubber is relatively low. However, with the continuous optimization of the industrial structure, the solution-polymerized styrene-butadiene rubber market has a large space for development.
