Shortage of Demand for Large-scale Installation of Production of Large-scale Equipment——Status and Market Analysis of Styrene Production in China
According to statistics, in 2003 China's total styrene production capacity was 1.05 million tons; with the expansion of Maoming Petrochemical and Qilu Petrochemical plant in 2004 and the 500,000 tons/year styrene plant of Shanghai Secco officially put into production in June this year, China’s styrene currently The total production capacity has reached 1.69 million tons/year. Among them, there are 8 sets of imported devices, and the total production capacity is 1.169 million tons/year. In addition, in 1995, China's styrene production was only 255,800 tons, in 2000 it increased to 736,800 tons, and in 2004 it reached 985,700 tons. From 1999 to 2004, the average annual growth rate of production was about 5.7%.
As China's styrene production capacity and output can not meet domestic demand, it needs a lot of imports every year. In 1995, the import volume of styrene in China was only 305,800 tons, and in 2000 it reached 1,157,500 tons, and in 2004 it surged to 2,889,900 tons, accounting for about 74.7% of the total domestic consumption. While importing, China also has a small amount of exports. In 2003, the export volume was 0.61 million tons and in 2004 it was 0.86 million tons. In recent years, the apparent consumption of styrene in China has continuously increased. The apparent consumption in 1995 was only 548,300 tons, and it reached 1,914,200 tons in 2000. The average annual growth rate of consumption from 1995 to 2000 was 28.4%; in 2004, it was 3,865,100 tons, 1999- The average annual growth rate of apparent consumption in 2004 was about 16.9%.
Styrene is mainly used in the production of polystyrene, ABS resin, SAN resin, unsaturated polyester resin, styrene-butadiene rubber, styrene-butadiene latex, and styrenic thermoplastic elastomers. Consumption structure in 2004 was 55.6% for polystyrene production, 11.6% for ABS/SAN resin, 3.5% for styrene-butadiene rubber/styrene-butadiene latex, and 7.3% for The production of unsaturated polyester resin, 2.6% for the production of styrenic thermoplastic elastomers, 19.4% for the production of pesticides, pharmaceuticals and ion exchange resins and other products.
Polystyrene is the most important derivative of styrene. Its products include general-purpose polystyrene, high-impact polystyrene and expanded polystyrene. In 2004, China's polystyrene production was approximately 2.15 million tons, and consumption of styrene was approximately 2.15 million tons. With the vigorous development of China's electronic and electrical industries and daily necessities and packaging industries, it will greatly promote the consumption of polystyrene resin in China. It is expected that the polystyrene demand for styrene in China will reach about 2.4 million tons in 2005 and about 3.1 million tons in 2010.
ABS and SAN resins are the second largest styrene derivatives after polystyrene. In 2004, the total output of ABS resin in China was about 600,000 tons, and the consumption of styrene was about 410,000 tons. With the consumption of styrene by SAN, the total consumption of styrene was about 450,000 tons. It is estimated that the total output of ABS resin in China will reach approximately 800,000 tons in 2005, and the demand for styrene will reach approximately 550,000 tons. Together with the demand for styrene from SAN, the total demand for styrene will reach approximately 600,000. Tons will reach about 800,000 tons in 2010.
Styrene is one of the main raw materials for the production of styrene-butadiene rubber/styrene-butadiene latex. At present, the total production capacity of styrene-butadiene rubber in China is 420,000 tons/year, and the total production capacity of styrene-butadiene rubber latex is approximately 140,000 tons/year. In 2004, the total output of styrene-butadiene rubber and styrene-butadiene latex in China was approximately 582,000 tons, and a total of approximately 132 thousand tons of styrene was consumed. It is estimated that by 2005 China's styrene-butadiene rubber and styrene-butadiene latex production will reach approximately 650,000 tons, and the demand for styrene will reach approximately 150,000 tons by that time and reach approximately 210 thousand tons by 2010.
Unsaturated polyester resins are also a major consumer of styrene and are used primarily for the production of glass and steel products, coatings, and construction materials. In 2004, the output of unsaturated polyester resin in China was about 900,000 tons, and consumption of styrene was about 280,000 tons. It is estimated that by 2005 China's total output of unsaturated polyester resin will reach approximately 1 million tons, and the demand for styrene will reach approximately 315,000 tons by that time and reach approximately 400,000 tons by 2010.
Styrene-based thermoplastic elastomers mainly include styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS) and its corresponding hydrogenation product SEBS and SEPS, etc., China's products are mainly SBS products. In 2004, China's SBS production was about 244,000 tons, and consumption of styrene was about 102,000 tons. It is estimated that by 2005 China's SBS production will reach approximately 280,000 tons, and the demand for styrene will reach approximately 115,000 tons by that time and reach approximately 140,000 tons by 2010.
In summary, it is expected that the total demand for styrene in China will reach approximately 4.38 million tons in 2005, and will reach approximately 5.6 million tons in 2010, with a market deficit of millions of tons to be filled.
