World SIS production capacity in 1998 was about 160,000 tons / year, yield of about 11. 60,000 tons of the Americas account for about 60 to 70 percent, Japan and Europe each accounted for 15 to 20 percent. 2002 SIS production capacity of about 350 000 t / a production of about 250 000 t, accounting for 15-20% of the total production of styrenic thermoplastic elastomers, which is 156kt Europe 49kt, 45kt, the brand has more than 10 varieties of about 30-40 species. After years of research and development, Baling Petrochemical SIS product quality and new product development, continue to make new progress, according to market demand has developed out of the SIS-1105, 1106,1188,1200,1204,1209,1225,4104, etc. SIS new brand, product quality has steadily increased, and completely replace imported products. Baling Petrochemical Company active in the SIS applied research, to guide the consumer market, the rapid development of the SIS application.
