China's tire industry is developing very rapidly. In 2015, domestic tire production accounted for 38% of the world's total. It is the world's largest tire producer and exporter. From 2009 to 2014, China's rubber tire tires and radial tires have an average annual compound growth of 11.2% and 16.2%, and the tire meridian rate has been increasing. In 2016, the domestic tire tire production rebounded slightly, but benefited from the increase in the tire meridian rate, the radial tire output increased by 13% compared with 2015.
Statistics show that in 2014, China's rubber tire production exceeded 1.1 billion, but after falling back to 900 million in 2015, the annual output of rubber tires has remained almost between 900 million and 1 billion. In 2016, the output of rubber tires in China was 949,740,500, a year-on-year increase of 2.31%, and a slight decrease in 2017, reaching 92,761,500.
In 2016, the output of China's radial tires was 63,511,900, a year-on-year increase of 13%, and in 2017, it increased by 5.65% to 671,070,400. With the overall development of China's tire industry and the continuous improvement of the meridian rate, the market for high-performance insoluble sulfur has broad prospects.
In 1927, Dums sprayed the sulfur melt into water to obtain polymeric sulfur. Industrialization in the 1940s, in the late 1970s, Crystex of the American Stauffer company achieved great success, the IS quality score reached 90%, and gradually produced oil-filled insoluble sulfur products. China began research in 1974. The former Beijing Institute of Rubber Industry Research and Design Institute of the Ministry of Chemical Industry was responsible for the successful trial in Shanghai Nanhui Wagner Chemical Plant in 1977 and the industrial production of high-content IS in 1988. After decades of development, China's insoluble sulfur industry has experienced very rapid growth. However, due to the dispersion of production enterprises in China and the disorder of the parameter standards in the industry, the production of insoluble sulfur industry is very irregular and the quality problems are serious. Insoluble sulfur will cause great pollution in the production process. Therefore, in the environment of environmental reform in the past few years, after 2-3 years of bottom process, in the context of supply-side reform, the rubber additives industry Since the fourth quarter of 2016, the economy has rebounded. In the past 17 years, the central environmental protection supervision, local self-examination and the Ministry of Environmental Protection have intensified the inspection of the air pollution in the “2+26” city for one year, making the main producing area of the rubber auxiliaries industry. The supply in Shandong, Henan, Jiangsu, Hebei, Tianjin, Inner Mongolia and other regions has been significantly affected. Some enterprises with environmental protection and technological upgrading are not up to standard, and those with weak financial strength have stopped production, shut down, and bankruptcy. Some enterprises have insufficient operating rates. The goods are tight. By 2018, China's insoluble sulfur industry began to recover.
