Oil – Extended Solvent – Styrene Butadiene Rubber, abbreviated as OE – SSBR, is a high-performance modified rubber.
It is produced by filling petroleum distillates (such as naphthenic oil or environmentally friendly aromatic oil) during the production process or subsequent processing stages of solution polymerized styrene-butadiene rubber (SSBR).
This kind of rubber has excellent processing properties, good low temperature properties and cold resistance, and excellent resilience.
From a raw material perspective, butadiene is the main raw material for the production of oil-extended solution polymerized styrene-butadiene rubber.
Changes in its supply situation and market price will largely affect the development trend of the oil-extended solution polymerized styrene-butadiene rubber industry.
From 2020 to 2024, global butadiene production capacity will maintain a year-by-year increase trend, reaching 18.32 million tons by 2024.
Among them, Northeast Asia, Western Europe, and North America are the world’s major butadiene supply markets, with production capacity accounting for 56%, 15%, and 11% respectively.
From an application perspective, oil-extended solution-polymerized styrene-butadiene rubber has a wide range of applications, involving tires, shoemaking, conveyor belts, seals and other fields.
The tire manufacturing industry is its main application area.
According to relevant data, in 2023, global tire sales will reach 1.785 billion units, a year-on-year increase of 2.3%; in the same year, global tire production will reach 1.82 billion units, a year-on-year increase of 4.0%.
Affected by this, the application demand for materials such as oil-extended polystyrene-butadiene rubber has been released, and its market has also shown a good development trend.
In 2025, the global oil-extended solution-polymerized styrene-butadiene rubber market size will reach US$1.94 billion, and it is expected that this value will maintain a compound annual growth rate of 5.1% between 2025 and 2030, and is expected to exceed US$2.5 billion by 2030.
Cambodia is one of the oil-extended styrene-butadiene rubber markets with great investment potential in the world.
On the demand side, the tire manufacturing industry is a popular application market for oil-filled solution-polymerized styrene-butadiene rubber in Cambodia.
Thanks to the relatively sufficient rubber raw materials, the booming automobile industry and the active strategy implemented by the local government to attract foreign investment, the Cambodian tire industry has developed rapidly in recent years, and the export potential of its products is relatively large.
According to relevant data, in the first half of 2025, the country’s automobile tire exports were approximately US$659 million, a year-on-year increase of 79.67%.
As an important raw material for the production of automobile tires, oil-extended polystyrene-butadiene rubber has a relatively large demand in the Cambodian market.
However, in terms of supply, the current Cambodian oil-extended solution-polymerized styrene-butadiene rubber market still relies on overseas imports, and China is an important source of imports.
Data show that in 2023, China’s export volume of oil-extended solution-polymerized styrene-butadiene rubber will reach 14,351.986 tons, a year-on-year increase of 168.23%. The export value will reach 6,281.1617 million yuan, a year-on-year increase of 7.73%. The average export price is about 11.45 yuan/KG. It is mainly exported to Vietnam, Cambodia, Thailand, Russia, Hong Kong, China and other places.
Among them, the quantity of oil-filled solution-polymerized styrene-butadiene rubber exported to Cambodia reached 5232.179 tons, with a value of 56.179 million yuan.
To sum up, in recent years, with the rapid development of the automobile industry and the continuous increase in tire production, Cambodia’s application demand for materials such as oil-extended polystyrene-butadiene rubber has become increasingly strong. However, in terms of supply, its market is still dependent on imports, and China is its main source of imports.
Against this background, Chinese oil-extended solution-polymerized styrene-butadiene rubber manufacturers have relatively greater opportunities to invest in the Cambodian market.
