my country’s integrated rubber (SIBR) industry is still in its infancy, and high-performance tires are its largest demand end.

Integrated rubber (SIBR) refers to a random copolymer made of three monomers: styrene, isoprene and butadiene through anionic polymerization. Integrated rubber has the advantages of high/low temperature resistance, low rolling resistance, good wear resistance, and good wet slip resistance. It has broad application prospects in fields such as high-impact polystyrene resin and high-performance tires.

The country attaches great importance to the development of the integrated rubber industry and has introduced many policies to support it. On July 14, 2023, the National Development and Reform Commission issued the “Guidance Catalog for Industrial Structural Adjustment (2023 Edition, Draft for Comments)”. The document proposed the development of high-performance rubber such as integrated rubber (SIBR), hydrogenated nitrile rubber, and pentadiene rubber. and production are included in the catalog of encouraged petrochemical and chemical industries. Against this background, the development speed of my country’s integrated rubber industry will further accelerate.

According to the “2023-2028 China Integrated Rubber (SIBR) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that integrated rubber has excellent performance and combines the advantages of single general-purpose rubbers such as butadiene rubber (BR), styrene-butadiene rubber (SBR), and natural rubber (NR). It has broad application prospects in the fields of synthetic resin and automobile tires. In the field of synthetic resins, integrated rubber can be used as a viscosity index improver and modifier for high-impact polystyrene resin; in the field of automobile tires, integrated rubber can be used to make high-performance tire tread rubber, and the finished product has good durability, Good elasticity and other characteristics.

In recent years, with the continuous deepening of research, the application scope of integrated rubber has been further expanded, and the market share of end products such as integrated rubber buffers and integrated rubber shock-absorbing caps has increased. Attracted by market prospects, my country’s enthusiasm for integrated rubber research and development continues to rise. Local companies and related scientific research institutions have applied for a number of related invention patents. However, at present, compared with overseas developed countries, my country’s integrated rubber technology level is relatively weak, and product output and quality still need to be improved.

The global integrated rubber market is mainly concentrated in Europe and the United States. Representative companies include Germany’s Haas and the United States’ Goodyear Tire and Rubber Company (Goodyear). my country’s integrated rubber industry is still in its infancy. Most local companies focus on research and development, and there are only a small number of companies with production capabilities. Sinopec, PetroChina, Jieshijie New Materials, Yulong Petrochemical, etc. are the main players in my country’s integrated rubber market. At present, the Petrochemical Research Institute of PetroChina has successfully developed a star-shaped arm structure integrated rubber.

Industry analysts said that integrated rubber, as a high-performance rubber, has broad application prospects in the tire field and will accompany the development of my country’s green tire industry in the future. As the pace accelerates, the market demand for integrated rubber will further grow. At present, due to factors such as high technical barriers, my country’s integrated rubber market accounts for a low proportion and the number of manufacturing companies is small. In the future, with technological progress, the prosperity of my country’s integrated rubber industry will increase.
