SK Advanced and Poly Mirae have begun commercial operation of a new polypropylene (PP) plant in Ulsan, South Korea. The 400 kta facility, based on LyondellBasell’s fifth generation Spheripol technology, is one of the largest PP plants of its kind in Asia. Propylene feedstock is being supplied by SK Advanced. As earlier agreed, Poly Mirae will offtake all PP produced at the plant for sale to customers in South Korea. The product will be exported throughout Asia through LyondellBasell and Daelim. SK Advanced has been operating a PDH unit in South Korea since 2016 with a capacity to produce 600 kta of propylene. Poly Mirae currently operates four Spheripol PP production lines in South Korea with a total capacity of 700 kta.
