Synthetic rubber refers to artificial rubber synthesized by chemical methods. It has excellent elasticity and is widely used in many fields such as vehicles, household appliances, and medical products. According to the characteristics of use, synthetic rubber can be divided into general synthetic rubber and special synthetic rubber. Among them, general-purpose synthetic rubber refers to rubber types that can partially or completely replace natural rubber, such as styrene-butadiene rubber, butadiene rubber, isoprene rubber, etc., which are mainly used in tire products and general industrial rubber products.

At present, the main producers of synthetic rubber are the United States, China, Japan, Russia, and Germany. With the recovery of the global economy, the continuous development of the automobile industry in emerging economies has driven the demand for rubber consumption. China, Japan and the United States continue to maintain their positions as the leading countries in global rubber consumption.

According to statistics, the cumulative output of synthetic rubber in China in 2017 was 5.787 million tons, a year-on-year increase of 4%. From January to February 2018, the national synthetic rubber output accumulated to 1.045 million tons, with a cumulative year-on-year growth rate of 2.5%.
