With the development of the economy and the continuous expansion of the application field of silicone products, the global silicone industry has been developing at a rate higher than the global economic growth rate, and the global consumption of silicone products in 1999 (equivalent to siloxane, siloxane and silicone monomer according to 1: 2 converted) about 670,000 t, increasing to 750,000 t in 2000, nearly 1 million t in 2004, and more than 1.2 million t in 2005. In 2006, the consumption reached 1.3 million tons, the level of silicone consumption is closely related to the level of economic development, the United States is the world's largest consumer of silicone products, accounting for about 35% of the global silicone product market, followed by Europe, about 33%, Japan accounted for about 15%. Due to the different industrial structure, there are certain differences in the consumption structure of silicone in countries around the world. In the United States, silicone oil is mainly used in make-up, paper, industrial defoaming agent, etc., and the market of silicone rubber is mainly in the fields of construction, automobiles and electrics appliances. Japan's silicone oil is mainly used in make-up, coatings and textiles, and silicone rubber is mainly used in construction, electric appliances and automobiles. In Europe, silicone oil is mainly used in processing AIDS, cosmetic crystals, textiles and paper and other fields, and silicone rubber is mostly used in the construction industry. Since the beginning of the 21st century, the economic growth rate of developed countries and regions led by the United States has slowed down significantly after nearly 10 years of rapid growth, and the consumption growth rate of silicone products has also decreased, but it is still higher than the average economic growth rate. The economies of developing countries and regions represented by China have maintained a high rate of development, so the demand for silicone products in these countries and regions continues to expand rapidly. The average annual growth rate of global silicone consumption until 2010 was maintained at 5%-7%. According to this calculation, the global demand for silicone monomers (measured by dimethyldichlorosilane) in 2015 is expected to reach 4.5 million tons.
